Hey all. I have a brand new ZZ502 in my 75 Corvette. It had a intake manifold leak (Accel SuperRam) so the the oil turned to a milkshake. It has since been drained but it looks like the oil is still getting water in it.
When we pressurize the coolant system it will hold pressure and slowly start to leak off. New antifreeze will drip out of the oil filter block.
This is a brand new long block from Chevy, it has been sitting since 2007 though.
Any ideas what to do next?
Mike
My guess would be tear it down and find leak. when it was sitting was it winterized??
It was not winterized but it was sitting in my garage here in CA, so it shouldnt be too bad.Quote:
