They are reliable if they've been properly maintained...There are thousands of them still on the road today!

Did you cut open and inspect your oil filter?

So cancelled my warranty and got the money back(most). Motors is ready to drop. Gonna find out what the problem is and go from there. Took Jake and Tony's on-line enthusiasts course, couldn't make the hands on. Cheers!

Found out it has Fabspeed exhaust in the process.

Dual Row as it is a 1999. Looks like all the oil is from the RMS. It doesn't look like it is in the same depth all the way around..

Picture of #4 intake. Lots of oil residue. Normal?

Any advice on teardown order to find the origin of tiny non metallic flakes? Lol

Get the tranny off.

Take it apart.

Check this site for the "Enthusiast" course, there hasn't been a new class posted since I took it a few months ago. It was good. They did mention there may not be another one offered as the demand was waning and they might be moving on to another series. Lots of good info. Only problem was I had some technical problems and missed out on 30 minutes of the most critical part of the reassembly discussion, and there really is no way to get it back.

I always find it interesting when a UOA seems to indicate no abnormal wear , and yet there are larger particles obviously in the oil. It is not producing small wear particles, only large particles 10 microns and bigger. It would insinuate that a hardened steel piece failed (like a piece of timing chain roller, or valve spring, or lifter bucket) and got sucked up by the scavenge pump and is chewing up the aluminum housing of the scavenge pump. I will be following this thread with interest, take lots of pictures.

I suggest removing your tailights. Looks like you removed the engine ok, but you may not get so lucky when you put the engine back in.

Left bank all looked ok. Did ask on another post if cam bearing wear was normal for 32k miles. Had one reply that said it was ok.
Really no metal in the little bit of oil in the head. Seemed like a lot of oil residue in the intakes.

Here are some more pictures.

Seemed ok. Is the worry breaking them when removing the bumper cover?

Thanks

Have you disassembled your scavenge pumps yet? It's a fairly common source of collateral damage debris.

Yes, easy to crack the taillight when removing the bumper cover.

I hope there isn’t too much damage. Debris getting into the heads causes a lot of damage, or at least potential damage you may not know about. Look under the “phaser” hydraulic actuator. There is a filter under there -check for debris in the filters.
