Looking to get some knowledgeable input regarding this report. While I know it says no immediate maintenance needed, there are some flagged levels. I am rebuilding this Camaro and trying to get every discrepancy fixed as I find it. Chromium being my only real concern if its my piston rings are going.
I've done cylinder pressure tests in the past and they were all about 150 psi. I have seen very small cylinder wall scoring with a borescope cam so that would be my only culprit so far, that or maybe its just from the coolant? I have noticed the engine does burn a little oil but nothing I'm worried about, esp with the oil separator on it. So again maybe there is some wearing of the piston rings? Is there any other thing that can introduce small amounts of chrome into the oil?
This is a rebuilt high compression 350 SBC gen 1 87 and up engine with profiler 195 aluminum heads, lots of Lunati and comp cam parts, scat crank, howarsd lifters, ARP everything, etc. Engine has 2,000 miles on the rebuild. Oil changes usually have a very small bronze like glitter but never any debris. This oil sample was from the oil filter. Engine had coolant leak at the intake manifold gasket in the past so this was the first sample from the second oil change and filter. Engine did also get a bit hot (260) at one time so will be checking the cylinders again. Recent test for a head gasket leak also came negative. Will be putting in AMSOIL 10W30 after this and taking another sample at 1k miles. I have added Torco Accelerator as well but I dont think that has any chrome in it. Thanks for any feedback!
