Hi Damian, I wanted to share my experience, hoping it will help your viewers and XK8 owners. I own a 2001 XK8, and have heard on several forums and XK8 owners clubs, that early engines produced after August 13, 2001 may still have plastic chain tensioners. Well, last week I decided to open my valve cover and I discovered, with great happiness, that mine are metal. My engine has the number 010821, so it was produced just a week after the update. Thank you for your videos, greetings from Italy. Giuseppe

Giuseppe, thank you very much for the information. This is extremely interesting. We couldn't find where the original date originally came from. We have been trying to verify the '13th August 2001' date with any official Jaguar documentation. However, we have been unsuccessful other than confirming its somewhere around that date based on engine and model year changes. A bit of a guess? Therefore, for you to confirm that engines slightly before that date already had upgraded tensions verifies the date is only an estimate and not the exact date. Much appreciate this information and contribution, regards Damian

This is an absolutely AWESOME video! Wish I had had it available before I did my tensioners 10 years ago. I had heard about the problem, and noticed rattling while driving. I knew instantly what was happening, and drove the car home very gently, fortunately with no failure. I got the latest tensioners and new chains, and did the water pump, thermostat, etc. When I took the tensioners off, they were in the beginning stages of failure, with cracks, but no missing pieces. So I didn't have to open the lower sump. Anyway, that's taken care of on my car now, but now I have transmission and drive mode problems and it's stuck in limp-home mode. I took the ABS box, opened it up, and took into where I work (Which has an aircraft avionics shop with REALLY sharp guys) and they quickly found and fixed a bunch of bad solder connections. That's where I stopped, and now I need to get back on the car and bring it back to life again. Thanks again for this video!

The more I learn about all the fun, travel and adventure people have had with various different chain-driven camgears, the more I realise that actually timing belts are not an inherently awful idea. At least they are a damn sight easier and cheaper to change on a reasonable interval (60k) and you get all the reassurance of a brand new water pump at the same time, plus you can do your valve clearances.

Most people are frightened of the cost and complexity of doing a thorough job. One thing less to worry about for quite a long time. If you have any tips from doing the job yourself don’t hesitate to suggest them. Thanks Damian

My tips concerning the tools shown: The screws coming with the Crankshaft Pulley Removal Tool (it´s always the same made in China, even if the boxing may have a different color) are too long and will penetrate into the engine front cover if no washers are used. The two bridges of the Timing Kit are useless if the primary chains come off first and the cam sprockets can no longer be counterholded by the crankshaft. To lock the camshafts against the high torque required for unscrewing these sprockets, you need brides with 3 (instead of 2) holes similar to the OE ones that can be screwed to the middle of the cylinder heads.

As always, nice job Damian. I can't believe for the life of me whatever Jaguar was thinking in making such critical parts out of plastic in the first place! Did they save $2 per engine in manufacture costs? I have a Kawasaki motorcycle (ZX-11) that uses a ratchet type tensioner tensioned by a stout spring. As it wears over time eventually the tensioner clicks to the next tooth thereby locking the adjustment so that it can never loosen. Don't understand why Jag never did anything that simple and bullet proof. You also mention that "rattle on startup". I actually get that a few times a year on my '04 4.2! I've never sweated it much because it's so rare and I have total confidence that I have the newest tensioners in it by virtue of the model year. I can only presume that sometimes a tensioner sometimes decides to bleed down since the previous shutdown.

@ODRModurol

Жыл бұрын

Paul, good point, I am sure the engineers had good intentions but didn't quite work out in this case. I believe the VVT units can allow slack in the chains if their seals are leaking and not retaining oil pressure. Thank you for your comment and input, regards Damian

I followed the shop manual ( mine is not vvt timing ). I locke the cams and the crank. I used the special tool to tighten the bolts and take slack off chain. My issue ? When I remove the tools and spin the motor I reinstalled the cam rails and the crank tool is a bit off .

@ODRModurol

4 ай бұрын

Mike, this might be the action of the valve springs moving the cam & timing slightly. It’s normal of one of the cams to be smidge off due to this. When you release the cam locks you might find the valve springs move one of the cams (think it’s the inlet cam on the RHS bank from memory). Make sure you lock the crank first and then should be able to relock the cams despite the slight movement, if the timing is correct, as it will recompress the valve springs . Hope that helps, please let us know how you get on, regards Damian

Fine sir, I have a question. After installing the “metal” tensioners, I have slack in the chain on the non-tension side of the tensioner assembly. I am afraid to reassemble the rest of this job until I figure it out. I assume as you say at minute 7, once I crank the engine, oil pressure will keep tension on the fixed side of the tensioner? Or am I mistaken and have something else out of time??

Plus could remove the locks turn the engine over manually using the crank ( put the bolt back in with a spacer). This should pump the oil enough to move tensioners into position. Once the engine turned over a couple of time, can then put the locks back in place to double check the timing is correct. Hope that helps regards Damian

Jag shouldve and couldve sorted any engine and transmission well and made the engine every bit as good as mercedes look r BMW or even toyotas best. That way their reputation would have been tip top. Theyre not bad and often are more reliable than many audi, merc, BMW or even Toyota and are cheaper motors than many and often get unfair criticism in some cases. There are some capacity engines and years that are really good but due to bad QC in the past and reliavbility and design gremlins, theyve now got a bad reputation. The truth is some mercs, audi BMW and some toyotas were BBV ad especially electrics on bmw and mercs and even bmw from 200p0 to 2008. Often they would last until the 3 or 4 year guarantee from new was finished then youd better have very deep pockets. Not what you expect on a £80000 + car. Disgusting.
