MG Rover K-Series Engine Rebuild Do's & Don'ts. Extra Hints & Tips

Автокөліктер мен көлік құралдары

During a recent K-series 1.8 rebuild of a poorly built engine, a list of Do's and Don'ts on engine rebuilds came to mind that I am sharing here. Let me say this is my personal perspective from analysis of this engine and experience from rebuilding others over the years. I am sure there are other more qualified experts on this engine out there, so by all means contribute and discuss in the comments but keep differences of opinion civil! Engine balancing is a larger subject that I didn't really discuss much as there are better videos out there, so please look up those and my balancing was a bit crude but still some improvement over standard.
For full rebuild details of course use a Rover / Haynes workshop manual. This video is just some extra points to check. For instance a lot of people have there own preference for head gasket, my preference is the MG6 and KV6 type of MLS gasket without aggressive fire rings.
Here's my older video with more build details on the k-series: • K series - How to Make...
HERE IS A GREAT NEW THERMOSTAT IMPROVEMENT VID: • K-series Thermostat. S...
As shown in this video: Do’s and Don’ts of an MG Rover K-series engine rebuild:
Don’ts:
1. Don’t Over-skim the Cylinder head. Min height 118.75mm according to OEM. Time 0:45 in video
2. Don’t use silicon, definitely not lots of it, on the Camshaft retaining ladder. Time 2:08 in video
3. Don’t over-tune it like adding a turbo without changing anything else! This engine had a melted piston! Time 4:28
4. Don’t ignore bad indents on the head, skim or replace. Time 6:58
5. Don’t ignore scatches or corrosion on the surface of the block. Time 8:02
Do’s;
1. Do use the N-series head gasket. My personal favourite. Time 8:26
(Also I should add use the 10.9 high tensile strength head bolts)
2. Use the PRT thermostat. Time 9:06
3. Use the stronger Oil Rail 9:26
4. Check piston/conrod balance between rods/pistons 9:35
5. Set the piston ring gaps (especially if doing a turbo conversion) 10:41
6. Locate the piston ring ends correctly on assembling. Time 11:37
7. Check Liners are even and protrude over the block 3 to 4 thou. Time 12:12. Also see fitting shim later at time 19:16
8. Align pistons correctly, arrow to front. Time 12:28
9. Clean out the hydraulic Tappets / Lifters. Time 12:55
10. Use liner clamps to stop liners moving on engine rotation. Time 13:23
11. Use steel head dowels and check depth/ height. Time 14:18
12. If using a ‘manual tensioner’ type cylinder head to replace an automatic tensioner style one take care to block unused holes. Time 15:19
13. If looking to buy a new head, check head height. Time 17:19
14. Grind out any water way flashing. Time 18:08
15. Fit liner shims if liners sunk or flat with block. Time Time 19:14
16. Seal the liners (and shims). I used Hylomar in the end Time 20:36
17. Check the oil rings don’t flip out and get bent while fitting. Time 21:43
18. Check for rusted pipes and leaks - e.g. water pump inlet pipe. Time 22:47
19. Check / replace if necessary the expansion tank. Time 23:18
20. Plug the rear (gearbox side) water hole in inlet manifold (a minor leak improvement). Time 25:12
21. Check for cracks in belts. Time 25:59

    Only sixty two comments, this excellent effort deserves far more. I have worked on numerous engines over the years and during the past twenty, concentrated on Rover T and K-Series. Have to say the latter, K-Series have always been a pleasure to work on. The latest being a problem MG ZT-T 1,8T which the previous owner had given up on. Collected the car with suspect engine issues but, drove OK. Part exchange taken in by local dealership who told me it had Head Gasket damage. No sign of coolant loss or over heating during the next couple of hundred miles.. Not for the first time, my closer investigations showed some evidence of abuse from those entrusted to care for the car. Will not go into details but, numerous pieces of evidence support this. Long story short, all four cylinder liners FLUSH with the surrounding cylinder block. Further inspection when Pistons and Con-Rods removed showed Ring and Piston Head Lands damaged by over heating. All four damaged to a greater or lesser extent. Evidence of over heating and being driven on when obviously something was wrong. Surprised it ran so well all things considered. Also poor of no antifreeze used resulting in the original cylinder liners corrosion welded to their block locations. Two middle ones came out easily whilst the outer two needed mush persuasion. They should all come out with ease by hand. Long story short, bought a set of new Cylinder Liners, Pistons ( 160 ) Pins, Rings and a set of liner shims 4 "thou", Shims cost £25 and the four piston assemblies cost £199 delivered to my door. All via eBay. Enjoyed fitting all that lot following a thorough clean up of all parts involved with the stripping and reassembly. Turned the key before starting the engine and waited a few seconds for the fuel pump to fully pressurise the fuel system. Then operated the starter. Immediate start. Never tire of enjoying that experience after all the work. Can confirm that engine feels and drives as good as new. Great engines if looked after properly. Well mine are.

He still treasures that car although he has several "better" cars at his disposal including his Lotus Elise with its 1.8K. Takes the little MG Metro to shows etc. That gift possibly sewed a lifetime's interest in Rover and MG cars. He now maybe knows more about K-Series than I do. He and his friends have changed K-Series Head Gaskets on the hard standing in front of my garage in about three hours. They know their stuff. I prefer to take my time and be thorough.

    My head was damaged by the fire ring indenting the head. That saver shim doesn't save anything. Eventually I popped an N-series on and shimmed fhe cylinders to 5 thou proud of the block. Tell you what, that Loctite 574 is pretty expensive. Less expensive than a new head, though, so well worth it! Thanks for the tips. Did my head a long time ago. Did all the upgrades. Going strong for +41k miles since, and I drive her hard. No issues or hiccups. **touch wood** P.S. You're right about the dowels. I had a cheaper Chinese MLS gasket with head saver shim (two of them went) and both had dowels that held the head off the block just enough that it dripped coolant out the side of the gasket. Not good!

    Well now,that is a great idea,i have 2 Rovers,a 25 and a 45,doing the head gasket on the 25 now,never thought of that!!! by the way,i had a new MLS steel gasket that ONLY last one and a half years!!! But now i will use the original old style composite gasket; the POS Victor Reinz or something steel gasket (wudahell would thing of a steel gasket...that is no gasket,it is a piece of steel, gaskets NEED to be compliant,steel is not!!) in which almost ALL the black sealing coating disappeared; Anyway, OEM, Payen BW750 or equivalent is gonna go on it this time,no more hype with steel ; a steel gasket requires a perfectly straight and polished block and head, AND it requires that ALL 4 liners' protusions abobe the block deck are exactly .003 inch,AND 4 ALL THE SAME, again because its steel, not really a gasket; not easy to achieve and you need a depth micrometer or checking with feeler gauges on those .003" .

    I'm an ex factory machanic. I've done many K series head gaskets. I find the multi layer gaskets to be not very good. I've fitted them and coolant and dribbled out the front of the gaskets behind the exhaust manifold when i've run them up. I've then fitted the original style gasket and no problems so i don't fit the multi layer anymore. I've not tried the N series gasket yet. That gasket was in secret testing before MG Rover when under btw!!! As for skimming the head, if the compression ring has only lightly marked the head, all is ok with a bit of wet n dry, but if there is a proper indent then it wants skimming. K heads can on be skimmed 2-3 times depending on how much they take off. They run like a bag of bolts if to much has been taken off. As our man says at 1:19 if that little groove (which was there to improve gas swirl as it was a lean burn engine) is almost level with the head its scrap.

    @paulrobinson3528 Yes I agree, I only use the elastomer head gasket if I have to do a head gasket change. The MLS are fraught with problems, originally developed by Land Rover for fitting to their K series engines, but only when the engine was new, not used. The N series gasket works well on the N series engine, with recorded mileages in excess of 200,000 miles! Again on a used K engine, as long as the head is in good condition, use the elastomer gasket because it does compensate for any minor vagaries between the block and the head. Lastly make sure the surfaces are immaculately clean before replacing the gasket as well.

    I hear that the MLS head gaskets are pretty unforgiving of uneven head and block surfaces. How true is that in your experience? Obviously getting the head a mild skim isn't much of an issue but it's more of a pain to do the block if it's mounted in a car.

Better to buy off someone private selling on a forum that maintains there own cars and knows what they are doing. There are a few user groups online and facebook groups around. If it has had a replaced gasket, try and look for one that has the N-series gasket, tell tale signs are little tags sticking out that hold the gasket rivet on the head gasket and those that have the PRT thermostat (although normal external ones or reconfigured PRT ones to work like external output side ones would be even better. More on that latter at some point).

    Personally I always use the N-series gaskets. They never fail catastrophically like the elastomer ones. If they do weaken it only results in a slight leak, but if you are careful with assembly they will be fine. Look for any surface imperfections and around the water ways and edge I put a very thin layer, spread with finger, of loctite 574. Not around the combustion chamber.

    I wouldn’t call myself an expert. Just passing on some if my experiences. The semi circle bit of the combustion space is, I believe, a squish zone where gases are squashed to encourage circulation, mixing and complete combustion.

    If you mean the U shaped recess on the side of the circumference of each combustion chamber, near and between the Inlet Valves, then I cannot explain the purpose of that. It is useful though for the DIYer working on K-Series Cylinder Heads. It's one of the first things I look for as soon as I remove a K-Series Cylinder Head. If it is absent, that is BAD news. It means the cylinder head has been over-skimmed and this can mean the poor thing is scrap! I have seen several problem cars I've investigated for myself and others where that -U- shaped recess is absent! Machined away completely in the pro-environment by those workshops who "We always Skim the head mate" often when it is not required. In over half a century of working on cars, I have only had four cylinder heads refaced by engineering firms. The first two, a T-Series Head which had been poorly machined so that the surface was worse than before the skimming, and a B-Series ( MGB ) which suffered from poor quality or more likely no anti-freeze and that caused corrosion in key areas. The other two were a 1.8 K-Series and the A-Series Head on my son's now forty year old MG Metro which had been stored unused for many years with poor quality/no anti-freeze, These last two were not skimmed, they were machined on a GRINDER. The helpful guys allowed me to video the grinder process. That was done by a small two man engineering firm here in the Cotswold in an old Cotswold Stone disused Quarry now with several Industrial Units. The finish quality of the ground surface of the cylinder head was far superior than any I've seen refaced with a skimming cutter! If ever I need to reface a Cylinder Head again I will have in refinished on a grinder as the finish is superior. Those firms who ALWAYS skim heads are best avoided in my experience. Often it is not necessary. It is simply a lazy professional way to clean up the cylinder head face which takes time to do it carefully by hand. For the DIYer that extra time cleaning the head properly is time well spent and saves the additional cost of an unnecessary head "Skim". Finally, the best gaskets "in the world" will not last long in a repair unless the all important cleaning, checking and preparation is given. On any car. Because of so much fake news about the K-Series, many folks ALWAYS blame the poor Cylinder Head Gasket when their engine overheats and so accuse the gasket of "Failure". Often the real blame lies elsewhere. They rarely ever fail, most times they are first DAMAGED usually by excess heat from the poor engine when coolant loss reaches reaches a critical level and it over heats!. Many reasons for coolant loss. Moral.. check the coolant level as recommended by ALL manufacturers. Trouble is, many modern car users do not even know where the bonnet release is on their cars. My friendly neighbour who drives one of those big yellow Roadside Rescue Service vans confirms this is widespread. When asking the car owner to pull the bonnet release of the stranded car at the roadside, he is often met with a blank stare. I fitted MLS gaskets* to three K-Series cars fifteen, twelve and ten years ago. Two still in the family's daily driver use and one a neighbour friends Rover 25. All well over 100,000 reliable miles now. Rocket Science it is not. It's the checking, thorough cleaning and caring reassembly which will go a long way to ensuring no repeat so called HGF. Cue .. "They all do that mate. Well known fact "In the trade". * Those MLS CHGs off ebay around £20 delivered to your door. Worth repeating, it is not the quality of the gasket which is the key factor here. It is the quality of the preparation, checking, cleaning and caring reassembly. I shall never tire each time I turn the key for the first time and the repaired engine bursts immediately into smooth running good health. Recommended.

    Yes, been there done precisely that six years ago. The SIX uses a conventional clutch and Flywheel. The ZT uses a Dual Mass Flywheel which is a straight fit on the MG6 Engine. One of the best and most successful mods I've ever done on any car. Mind you, I had driven the donor MG6 a few months before it met a premature end. So knew the Chinese Engine was a good 'n. There are numerous improvements with the Chinese Version of the K-Series when both are placed alongside for comparison. The best being unseen. Part of the improved casting process for the major engine components. Learned that from one of the guys up at MG Motor. Pity the good folks up at Longbridge were denied the opportunity to implement them!

    tell me, after assembling the motor, a month. a ringing sound appeared (like hitting metal with a metal ruler). with crankshaft frequency. the sound is similar to a bad hydraulic lifter, but is heard better from below. when warming up, the sound becomes quieter. and sometimes it is clearly audible. what problems could there be? oil pressure on a hot engine is 1.6-6 atmospheres.

    Possibly sticking Hydraulic Lifters. If oil maintenance has been neglected in previous ownership, "thick varnish" build up slowing the lifter's ability to quickly return. Hence the extra metallic noise which reduces when the engine warms. I drain the old oil HOT and fill the engine to the correct level with DIESEL FUEL. Which is of course Oil. Then run the car GENTLY for about 10 kms or 6 miles. Then drain hot and fill with good quality brand 10-40 Semi=Synthetic and new Oil Filter. Always works for me with much reduced engine noises. Valve gear noise reduced to and acceptable "rustle".. like new. WARNING, Although I have used this method for over ten years, it does work for me but I am NOT recommending it just in case it does not work for others. It does work for me and sometimes spectacularly so. Better sounding engine, better throttle response and even improved fuel consumption. So if you decide to try it. do so sensibly. Keep those engine revs below 3500rpm and mostly less avoiding any steep hills needing larger throttle openings...Drain Diesel Fuel hot immediately. You be surprised the muck it dislodged from the engine's internals. That nice clean and clear Diesel Fuel will be Black full of contaminants after draining. .

    To be honest I am not sure if that year has those improvements. Try and be sure where the water is being lost. It could be the water pump leaking which is easier to fix, or a radiator leak, or a hose. If it is the head gasket there should be a loss of compression on a cylinder (use a compression tester) and probably steam / smoke from the exhaust.

    @@radimadamovky-sl4qd A cracked head or block is unlikely. To check if the water is going into the combustion chamber, buy a cylinder compression tester (not expensive) and test each cylinder for the compression value, with all of the spark plugs out. If water is getting into the combustion chamber then one of the reading will be lower than the others. Also often you can get oil mixing with the water or water in the oil so look for that. If the head gasket was recently changed it is probable that it wasn't done properly.
