    A suggestion: while expensive, it might be pertinent to actually go and clean up ALL the corrosion in the valley and then coat it in a layer of Alodine like what would be done in aviation on aluminum, just as a peace of mind thing. You can't gain back the aluminum, but you can at least protect the aluminum you do have from corroding. Generally it's used for creating a surface for paint to stick to in airplanes but in your case, I'm wondering if a few coats of that won't hurt, and then some high temp engine paint in something a bit brighter so you can see any oil leakage in the future.

    I would consider using block fill to just fill in the valley up to just over the top of the oil passage. Block fill is designed to withstand a lot more pressure than this engine will ever see and would seal off the block from any outside material. Once cured the block fill would restore and increase any strength loss the engine block might have experienced. Just a thought.

    Pro tip - forget about that metal pipe in the valley (not the Y pipe, the foot long one leading to the heater core). Just run a long silicone or rubber heater hose out of the valley. Eliminates 2 seams that could leak that are impossible to get to without removing the manifold again.

    I've used this method with outstanding results. Cleaning that valley I'd use a Dremel Tool with the extension shaft and a cup style wire brush, it's easy to control the pressure without gouging any more holes, gotta use a little finesse while doing this, and all the while using your shop vacuum sucking up any accumulated debris. Then follow up sealing up the valley with the many suggested materials from your viewers. BUT no more poking around in there with screwdrivers and other sharp metal tools!

    I personally think you should clean the valley as best as you can, then coat it in Alodine. I'd go as far as reinforcing all of the deeper pockets with aluminium weld, coat the whole thing in Alodine, then fill up the valley with JB-Weld to also make it slanted towards the front, so it could drip out of the valley, if there would be any more leaks.

    If you're considering replacing the engine anyway, I would remove all the corrosion, coat it with POR15 then fill the valley to level with JB weld which would eliminate any place for future moisture and dirt to gather. JB weld is heat resistant to higher than intake temperature. Between the POR15 and the JB you should be okay. There are chemicals out there that will remove corrosion from aluminum. Believe it or not, Evaporust removes corrosion beautifully from all kinds of metals as well as rust, though I've never tried it on aluminum, it certainly wouldn't hurt to try.

    Have you considered flooding the valley with high temp epoxy? The liquid epoxy would fill in all of the voids and be held in by them. And it'll resist heat while sealing it off from further damage, and prevent further deterioration? Not JB Weld, actual high temp epoxy. As long as the surface is prepped properly it would be an effective preventative. Just a thought to help that original engine last long into THE FUTURE!!!!

    I was thinking that. Something strong but still have some flex to it so it won't crack or seperate with the constant heat cycles. Just flood it on and let it fill in everything. If it was further gone or already starting to leak if it was mine I would try it. Not much to lose. Even in the shape it's in I would consider something like it that protects what he has left from getting worse as it seems under the best conditions it's a place where dirt and chemicals like to build up and not easy to clean. Having basically a clay shield over it the last 30 something years might have caused the damage you see but prevented far worse from getting to it.

    When you do end up restoring the A/C system, I'd personally suggest using the original components (with new o-rings and expansion valve of course) and charging it with RS-24 (R-426a). It is a drop-in replacement for R-12 that is compatible with the original mineral oil used in those systems. If you convert it to R-134a, you will be disappointed with the performance of the system since the condenser coil is not designed for it. In addition, you will have to remove any trace of mineral oil from the system and convert it to PAG or Ester oil, which is a big pain. I have used RS-24 in two of my cars originally designed for R-12 for 6 years now, in my experience it works just as well as the R-12 originally did, and didn't require an expensive new condenser designed for R-134a.

    Crazy idea that I've seen that works. I've used Hy-Poxy's H-450 Alumbond (epoxy designed for aluminum and aluminum alloys) for engine repairs as it was a last ditch effort to repair it. Previously tried using a welder in my area that was a family friend and worked on restoring classic Ferrari's. With that kind of experience, I thought he'd be good...but he couldn't get it to work. I cleaned it up REALLY well. I heated it with MAP gas and the non-flammable brake cleaner using sand paper and wire brush (the important part is to use non-flammable brake cleaner if you're using flames...don't ask). After I felt it was perfectly clean and the aluminum pores were free from oil and dirt, I hit it once more with sand paper and quick squirt of brake cleaner before coating with the Alumbond to remove any recent oxidation. I've got to say that it work much better than I had expected. I was able to ride that motorcycle in all conditions and it work great! Previously, it leaked oil continuously, making it unsafe to ride. I wonder if coating the valley of death with H-450 would work to add an additional layer of protection? It worked well on my water cooled engine (motorcycle). It sealed up a nasty oil leak that had occurred from a broken chain (previous owner). Additionally, it dries in a nice aluminum color. At first, it's runny, but as it is continued to be stirred and getting into it's workable time limit (about 45 minutes), it starts to thicken up a bit. As with any product, preparation is key. Finally, mileage may vary.

  • @leeweinstein5372

    You should clean the aluminum in the valley really well and fill it with a good quality epoxy. Consider chemical cleaning and epoxy primer first, and something like 3M DP-420. It will outlast the engine. I've used it to repair engine blocks in the past and worked great.

    Another solution is a product called "Glyptal". It is an insulating coating that I’ve used in the valley and heads of my Windsor Ford motor. Used it more for oil return flow, but it is a nice thick coating that will survive inside your valley and also stop corrosion if water gets in there. Sold by different places.

    Hi Alex Enjoying this series. I can see what you mean about the valley. There has been some corrosion going on there. But it’s not currently leaking which is really good. If I was you I would look to prevent any further corrosion. I would clean it up 100 % and paint it with clear coat prevent it getting worse. Then inspect on a regular basis to ensure it’s still good. If you can find an engine in better condition for a good price might be worth having a spare. However I think that having a working original numbers matching engine would be more important to a purchaser than a perfect valley.

    I'd be careful with any coatings on the block. I spent probably 15 hours cleaning the block on a DeLorean and sealed it according to a forum post and the first time I had to remove the intake again, there was unavoidable fuel spills into the valley and all of the coating came right off. I did have a much much worse block than this one and anticipate having to replace it at some point so I used an aluminum epoxy on the worst looking bits and that is probably better than any coating. About hard as the other aluminum and really well bonded. Pointless? Maybe, but it was my friend's car and he wanted to experiment instead of proactively replacing the block.

And as a former mechanic, who is nearing 50 (and has seen a ton of car stuff...and tends to ff often) I watch the majority of what you do. Not only is it interesting mechanically but your personality and natural commentary easily maintains interest! You're beyond roads!

    Kind of curious, would a high temp silicone sealant to protect the aluminum block work in that area? Not a car guy so don't know but I have worked with industrial tools that get high temps and know that there are some high temp silicone sealants that are used to protect the tools from corrosion. Wondering if the same thing can be used on car engines. Something to prevent the valley of death scenario.

    POR15 paint would definitely help prevent further corrosion of the block. I bet you could gently clean the block with a wire brush and then apply POR15.

    I would get a die grinder with a wire brush attachment and polish the valley of death. Once all the corrosion is removed, I would use chromate conversion (Alocrom) and then etch prime and 2 part epoxy paint. You can then forget about the valley of death ever being a problem again.

    You should walnut blast the valley to clean up as much of the corrosion as possible, then put some anti-corrosion coating (Alodine?) and then fill the valley up to the webbing with JB Weld epoxy.

    Alex an outstanding job on bringing the DeLorean back to life! If you wanted to take this car to the next level an LS swap would do that. It also wouldn't hurt on the subscribership angle because I think a lot of people would be interested in it. An LS swap would give you some outstanding continuing content!

    Honestly if I was trying to preserve the original engine I feel like I'd get the metal all cleaned up, rust killer spray and then probably try to coat the whole area in epoxy thoroughly to reinforce any potentially weak metal. At the very least it would limit how much a thin part could fatigue and if something did break it would more likely present as a slow leak rather then total oil pressure loss. At least that's my theory.

    For the a/c system . It uses r12, if you convert to 134a, your gonna have to install an extra fan to keep it cooler with a temp activated switch. Because ure going from basicly mineral oil to gas. It has a diffrent way to exchange heat. For the engin top end, i would just leave it, engines that old look that way. But is always a good practice to have a extra engine aroung if there is a mishap in the future. Just rebuild the new new doner engine and wrap it with plastic and set it aside.

    The engine valley is fine brother, i think the biggest thing is keeping all that junk out of that valley. Like any other kind of metal, wet dirt is really great at deteriorating it. I'd probably spray it with some fluid film at the very least to try and protect the aluminum for as long as possible. Anyway shes gonna be one nice set of wheels to enjoy yourself in.

    The pitting on the Valley of Despair appears normal for any vehicle out of France, late '70's/early '80's. My Renault[s] 16, 20, Fuego and 25 all had scalloped alloy panels, gallery passages and undertrays. Nothing broke - admittedly, none had a V-configured engine !

    The engine was upgraded and used by Renault and Peugeot until 1996, and sold to Fiat for use in Lancias, so at least finding more reliable parts shouldn't be too bad. Working out which bits can be used to improve on what you have is the trickiest part, but maybe someone has already done that.

    Clean that valley even better, then acid etch it so its super clean bare metal, and then skim coat it in JB weld, paying special attention to getting all the very pitted areas well filled in. Once dried you could sand and paint which would the seal the entire valley against further exposure to standing moisture.

    If there is still substance left you could weld the deep areas you have a master welder available, ask him. If there comes too Much tension caused by the heat you could anneal it again. You do need to disassemble it completely though, but that’s what we all like looking at! And while you’re in there do some tuning. This was definitely the softest engine in the 80’s good for heavy volvo’s but absolutely not an engine for a sportscar. There was a 3.0prv turbo in a renault A610. Turbo. But still only 250Hp. I bet you can do better

    I think that block can live for a long time. I would attack the corrosion on top and seal it with some anodizing coat or epoxy. Once sealed by epoxy it should not further detoriate; so not leaks today will mean no leaks for a long time. As usual you guys are doing a great job, thanks for the video!

It would probably make it more fun and make your more likely to drive it on the regular. While your in there you might as well add an airbag suspension that would let you drop it super low

    For the AC you don't need to change to 134, just get the duracool or 12a refrigerant with an adapter for the fill connection. Don't have to change anything in the system. Works better than 134. My 71 buick riviera still had pressure in the original system so I was able to recharge and it works great.
