So, I was getting ready to mount up the turbo... again, and I pulled the sump for cleaning and found this....
Any chance it's NOT the remainder of a cam bearing shell?

Paul, is this a rebuilt engine or just a top end job?
Sorry to say it but, I would tear it down and investigate where that bearing shell came from.

This motor was previously turbo charged and suffered some detonation damage, rings and cylinders
Originally my intention was to replace the damaged parts and the heads that had chambers too small really, to be used for a turbo application.
The small rod ends are still smooth and showed no signs of slop.

I know your wife heard the head leak while you were out for a drive.
What I didn't see in your thread was weather you did a full build when you replaced the heads or, if you just top ended the engine.
Either way, you need to know where that bearing shell came from before moving any further forward, IMO.

It was just new Mahle pistons and cylinders and new turbo heads from Greg Tims. I never intended to split the cases. The motor has less than 1000 normally aspirated miles, and I never had any problem with it.

Maybe it fell out during case assembly, I can't think of anything else. You know you'll have to split the case whatever. |

Sadly, yes.

1000 miles... hows the case? Did the cam tear up the bearing saddle?

I think we have a winner here.
edge of that thing looks too rounded vs cam bearing being more of a 90, also looks like thing has the same cut / taper as the fingers in the sump screen

At first I was genuinely going to ask...which part? Because I do not work on many type 1's...and just could not visualize it....but I think he is correct!

Radius is all wrong for a cam bearing flange.
You should be hearing some stuff slapping (knocking) around in there if anything is missing that much bearing.
Width is just about right to be a part of the oil screen. So is the radius.
And it has scrape marks on it, the kind you get when you push the oil screen up onto the oil pickup tube.
Hopefully that's all it is. Do you have an inspection camera to poke up past the pickup tube bell and take a peek around in there? |

As BFB and Ray indicate, It does appear to be from the sump screen.
I freely admit my initial assessment was incorrect.
