BoxsterLS376 introduction - LS3 conversion :)

My best guess is that it is a piece of valve cover broken off when the oil fill was knocked off. I think the valve cover was replaced but the broken piece was not recovered... at least that is what I am hoping~ :/

Hang in there because it will be worth it. I just spent New Years Day carving canyons with Scott Mann of Renegade in his LS Boxster. That thing is a monster that looks bone stock. All the 930 Turbo guys were suitably annoyed as you might imagine.

Awesome build! I'm very tempted to try to do this myself. Can't use a crate engine and pass smog in California though. You have to use an engine pulled from a newer car. Looks like the stock Corvette cats would fit since they are so close to the exhaust manifolds.

I wonder if it would be possible to use the LS4 water pump and accessory layout? It was mentioned in the Cayman + LS3 thread on LS1tech. Might be able to avoid having to use an electric water and power steering pumps. Looks like the alternator position would be a problem.



Bummer about the engine. At least you caught it before you fired it up.

Thanks everyone!

Well good news - ish~ After sending pictures and videos to Chevy I just spoke with them and they advised to proceed with installation. We are 99.9% sure that the chunk is from a broken valve cover filler spout. The oil filler was clearly knocked off at some point and the valve cover broken and replaced, but obviously the broken wasn't recovered until now.

They did give me the option to go ahead and send it back to them but it would require putting the motor back to stock configuration. Even if there is a problem it is under warranty so I can send it in later, plus I they mentioned that the warranty may also cover part or all of the removal & reinstallation of the new motor. So it would definitely suck if there is a problem but I think we will be ok.

sooo BACK TO WORK!
