alright i did a gt40P head swap amongst many other things to the motor and it goes like a raped ape now but has a problem.
Exhaust gas leaks into my coolant system, but no antifreeze gets into the oil or gets burned, the displaced coolent just goes into the overflow tank and doesn't return do to exhaust gas taking up space.
I had this issue and took the heads off and no gasket problems, bolt torqing was correct at 80ft/lbs now, 75 the first build, gaskets were on correct and the shop gave the heads a check for warping which turned up good also. So i put it all back together again and still have the same damn problem. I put in a bottle of stop leak to keep the coolent displacement at 1" per hour of driving for now. I did a very close visual inspection for cracks and found non but i did no magnafluxing. Compression check turned up good at 130psi on all cylinders, and no steam cleaning in any cylinders. LOPO engine was perfect before build, besides the 150 hp.
so if you guys can figure out what could be doing this tell me your ideas.
thanks, andy
