I have a 1991 GTS-t, I just installed a new Tomei metal head gasket. Started it up let it idle till it reached full temp, turned it off, re-torqued the studs and took it out for a drive. I drove it around for about 30mins, and then it just died all of a sudden. After that the engine won't start anymore, and when starting it the starter struggles to turn the engine over. It spins a few times and then its like it hits a wall and has trouble spinning it,.
I thought maybe the head gasket didn't seat properly and some coolant leaked into a cyl and it was trying to compress the liquid in one of the cylinders, but I took out all the spark plugs and all pistons are dry. Also, when all the spark plugs are out and I turn the engine over it spins freely. Anyone got an idea of what the problem could be.
