Hello All
well the dreaded day finally happened...an engine knock. Its a 351W 69 block, 60 over. It was built about 7 years ago with only 3800 miles on it...till now no problems with it. I have a 6000 rpm chip in the MSD and I don't think I have ever used its technology
No loss of
oil pressure. It starts up fine and is quite as it warms up and the
oil pressure starts to drop down...at around 1700 rpm and above it knocks.
I have been looking for the easy problems...rocker arm push rod lifter....but to me those would be a tap and not a knock. They all seem fine
I changed the
oil...nothing in the oil as I drained it over a screen...no gold glitter in the oil etc. no smoke, no oil in the water or water in the oil
any suggestions....?
I am not sure what the next step is...Pull the intake and look at lifters...It has been suggested to me a cam bearing....not sure what I can see from the top. The noise seems to be at the head gasket level of the block not down low. You can "feel" the knock in the engine
If anybody lives in NE ohio (Willoughby Hills) and knows anything about small blocks...drop me an e-mail you are more than welcome to stop by and listen
thanks for any any and all help
John
