Please provide any guidance if you have experienced this. EFI upgrade on motor. Ran perfect at end of season. In off season swapped the intake to Holley EFI manifold. New Felpro gaskets. Gasket maker on top and bottom of cork at front and rear. Mid way installed the metal cover in gasket to block center ports on both sides. Doing this I did remove valve covers and exhaust but replaced with new gaskets
Issue. My mechanic that rerigged and installed in boat after I did this work when cranked the motor my starter broke. Then he pulled spark plugs to see if he could rotate motor by hand and water came out of 3,5,7,4 cylinders. We were hydrolocked but spins free now.
He is leaning towards a bad head gasket as he does not believe water would leak down past intake manifold into cylinders if I screwed something up during swap. I cant wrap my mind around it being a head gasket. That means my perfect working motor blew head gaskets on both heads while not running during offseason.
He is troubleshooting this tomorrow and I have all the faith in him. They built this motor 10 years ago and never 1 mechanical issue. Its a BBC 540. Maybe one of you has some idea that can shed some light.
