Looking for some feedback, considering picking up an RS4 engine. Has compression between 165-190, leak down was less then 10% in all cylinders. Engine was found to have cylinder scoring. Oil is getting into one of the downpipes causing a rich code on bank 2 and a lean code on bank 1. This all came about because one side of the engine had a large amount of white smoke coming out of it. Thats about all I know, I have never heard of engine scoring to cause an issue like that, sounds more like rings? I was considering picking it up to sleeve and rebuild with OEM components. Reasons I am considering this: Yes I know JHM is working on a program, I have already been in touch and they are not currently taking any more engines on at this time. Engines are not easy to find used, I have some methods of getting a low mileage one but I do not know when that would be. Thoughts? Reasoning?
I think it’s a lot harder than “picking it up and sleeving it” Even if you plan to use stock components. I would be more concerned with the walls being warped too, not just scored. Do you truly have confidence in a place that can sleeve this block correctly. I mean JHM has been at it for a while and have ran into the good, bad and the ugly of both the BHF and BNS. They have probably put a ton of money into R&D, more than I can even guess at.
I think it would be cool to pick up if you can get it cheap and preserve it or have it inspected in more detail to find the true issue. Then when the built motor program is going in full swing it will be the perfect candidate. Letting a machine shop learn on a pretty rare engine will usually end up in more bad than good.
The description of the issue makes absolutely no sense though.
I would agree that the seller either does not have a clear understanding of whats wrong, hasn’t explained it well, or the shop misdiagnosed it. Yes I would have confidence in the shop sleeving it. And I agree, picking it up at a reasonable cost would be worthwhile.
Being active in the Porsche community more and more over the past year. I’ve seen several variations of this topic with the aluminum motors. They’ve shown that trying to save a motor will cost you twice what it would to rebuild a good motor. Better results still appeared to come from getting a good low mileage motor. This is also taking into consideration that there are already sleeves for those Porsche motors and several shops experienced installing them.
From what I’ve observed with the aluminum Porsche motors in this situation, it’s best to not get involved with a damaged motor to that degree unless you have no other options.
Pick it up on a cheap, it would make one bad ass coffee table ;D
What do you plan on putting this engine in?
Oh that works

Nice car!
Is it the same one the guy was selling on the other forum supposedly with blown motor for really really cheap? I think dealership offered him like $4k for it and he was fishing for best offer over that.
Nope, someone snatched that up real quick for I think 6-7K from NJ. This one is a former car from an AZ member though.
That’s the other nj car. He hydro locked it didn’t he? Thought his name had some vw reference.
yup, NY car, he hit something cause of how low he was, cracked the oil pan pick up tube and spun a couple bearings at a minimum. Oil pan was never cracked or anything so it didn’t show a low oil warning, idk it didn’t give him a low oil pressure warning though.
Literally the fastest colour
…for now
Fastest stock colour is Avus anyway
Fastest all motor colour is Phantom
Fastest street trim is Sprint
Fastest gutted with drag slicks is ??? (What was that apr car?)
Daytona
I feel like picking up a used motor can be just as chancy if you don’t know its history. There are a few over in Europe for sale but if there was ever a problem with it, that would be a nightmare sending it back etc. A member on the east coast just bought one from over there for like 7500 shipped with 40K miles. The other guy from AZ in LI whose motor crapped out, bought a rebuilt one that shit the bed within 1K miles before getting an Audi Reman’d engine. I know of a few motors floating around though. Just exploring my options.
Not sure that’s entirely responsible of you to just post that without context. Some google searcher finds that and there you’ve gone and spread bullshit. You may want to also mention that he had unitronic for 2 years before that, and the exact tune he had on his car has caused absolutely ZERO mechanical failures on anyone else’s car. Just for the record.
Did he change tunes at some point there?
I was not implying that it was any fault of the tune, more so how funny it was that people were trying to blame a tune that was on there for a few miles and not acknowledging that he had the unitronic tune for thousands of miles that would have been a much more likely culprit then one that had been installed on hundreds of cars with no problems. But you are right, out of context that could be misinterpreted. But to keep this on topic about a engine rebuild…
