Re: Low oil pressure in ZL-1
BAD THING! The 074 heads don't use the heat crossover and it is a dead end and does not go to the water jacket. Your heads need to be pressure checked. Should have no water. The head bolts in the ZL-1 block are blind-they don't go into the water jacket and only require oil on the threads. The 4 extra head studs go into the 4 intake ports and need sealant-do not use silicone it is not gas resistant. Man, these ZL-1's are different animals.
