This is a great video. Definitely explains a lot of the short comings of the block. Thanks for sharing your findings as these issues should have been recognized by the aftermarket shops years ago before tunes came out
The liners of EA837 Evos is quite similar as 839. But 837 came with much smaller bore spacing so even more restricted with dry flange sleeve. For 837 block reconditioning we almost only recommend wet conversion for reliability
What was the initial cause for the failure or for this motor coming out in the first place? I have a B9 S5 so I’m curious… Also how did the the needle bearings for the rockers look? Were all the needles still in the bearings? What year car did this come out of?
This engine came out of a 19 B9 S4 IIRC. The car was tuned to run 500WHP with hybrid turbo and eventually blew his head gasket. If you run with stock power, the factory block will be all fine but if you go with some aggressive stg2 tune or bigger turbo, the engine will not hold for long, maybe less than 20k miles. The rockers out of this very car look all good.
the 4th one so far. We only developed the wet sleeving for ea839 6 months ago. Still fine tuning the sleeve shapes especially for the cylinders on the side.
Ill be fair iv3 been running around 500whp and this issue did not happen at all with me this is genhinly the first ever block ive seen with anything like this

I will cancel my Netflix subscription and continue with PPM LAB 😁
very interesting video learned a lot 👍
Awesome video. What about the EA837 Evo, aka "CREC" engines? Unlike the original EA837, CRECs also have cast-iron liners.

@@ppmlabofficial also interested on where you are located and if this is something you do regularly.

@@ppmlabofficial What about stage 1 tunes ? Would stage 1 with stock turbo cause this problem ?
@@Shulcyo Less likely than high boost setup, but we have seen 1 stock power with blown gasket
Where are you located? How much does this cost to have done.
What is the price for this service ?
@@Shulcyo depending on the setup, starting from 5k USD

Plenty of failures happening but it's inconsistent it seems. Lots of people blame the tunes but it looks like LPSI might also be an issue
Not all high horsepower 839s will run into problems. But if shit happens, the design of straight cast iron liner is definitely to be blamed
Your website needs some attention. EA389 page is full of "blablabla" and "sentencesentence"
apologies, website still in construction, will get it done asap
