We are going to pull the motor and see what happened inside, "Stuck Oil Pump Check Ball" or "To be determined." I flushed the oil a few times but still seeing shiny particles in both heads with valve covers removed. Oil pressure does not vary when running 10/40 or 20/50.
Oil pressure keeps going lower. No more engine starts. I needed to address a rear oil pan leak, Chewed up Flex-plate from Rough starting issues and will be putting in the LSM Camshaft. LS1 Firing Order, 252,258 Duration @ .05 112 LCA .660 Lift with 1.5 Rockers. .726 Lift with 1.65 Rockers Camshaft was Designed by the owner of LSM. Acquired Parts Below: Steve |

We pulled the motor, Pulled a few rod caps and small pieces of Copper were embedded into them. Pulled the Camshaft and large grooves were dug into all of the Cam Bearings.
Thrust checked in at 11 thousandths. Top End disassembled and brought everything to the Machine Shop, R&L in Dover, NH. I am having Leo go through the Heads - Disassemble, Clean and Reassemble. He went through them in 2010. The Block will get Honed and all new Coated Bearings installed & Polish Crank. And anything else Leo comes across will get fixed. The Oil Pump check Ball was not stuck open. Steve |

What did the main bearings look like? Check the thrust surface of the crank.

Hi Tony,
I didn't pull the Main caps, I asked the machine shop to see if he could determine what caused the damage. We did notice my torque converter had the head of the flexplate bolts riding on it, as the paint was gone with slight impression on the torque converter, the flexplate bolt heads showed slight wear too. This was shimmed properly with washers when first installed and there was about an 1/8 inch gap. The converter has anti-ballooning plates. The push-rods are comp cams - welded ends. Steve |
