I guess I have a rebuild on my hands, #1 Injector was stuck open and ring wash the cylinder 😭.

Does this explain where the metal in your oil filter came from?

Probably not, I did an oil analysis and it came back good.

Sub'd - we can learn a lot from this thread. Thanks for all the videos and great photos. Thanks also for the "fixing the carbon roof "DIY video. I'm glad people such as yourself are now restoring E9X M3s. These cars are special in my book, and I've driven a lot of stuff over the years working here https://michelinpg.com/ Sorry to see the bore scoring on the scope video. Perhaps it's time for an overbore and stroker crank? Or maybe just hone and finish the original block.

Subbing to follow the build. Love what you are doing.

And I love even more that you are not going for a fancy show car build, but restoring it to what it was meant to be. Bummer about the ring wash. Did it seize the motor?

Many s65 have been lost to a stuck injector....

Thanks appreciate it, luckily it’s not seized. Nah no show car, I enjoy driving way more.

Engine is out, just waiting on timing tool to tear it down.

Main bearings??

Previous owner had dropped a bolt inside of the engine, luckily it didn’t cause too much damage.

Yikes! I wonder how a person could do such a thing? Thanks for all the photos, videos and updates. Do you think it could’ve just come loose?

Wasn’t missing any bolts from inside of the engine.

Do you know how many miles are on those rod bearings?

130k, I was surprised how great they looked.

Those look like aftermarket bearings from the color, how would a bolt have gotten in the oil pan other than from a rod bearings job? The oil cap?

It looks like original OE bearings.

That's rough but excited to see what will you be doing next! Subbed btw

Based on this picture below (which you posted above), I speculate the rod bearings have been replaced at least once. Perhaps the CarFax or previous owner records may show that? There's a dedicated thread to rod bearing examples (linked below) and if yours really are original OEM at 130K miles, then you now hold the record for the best looking OEM bearings at >=130K.

Maybe the secret to bearing life is excessive carbon.

Found out you can call Mahle and they will build you custom piston. Wait time is about 12 weeks. Hopefully I get than early.

Just wondering if you'd got them early? How are things going with your E92 M3? Any updates?
