Question about 1987 Ford Ranger
88 Ford Ranger, 2.9L V6, compression in all cylinders is 140 to 160psi, no adjacent cylinders read the same pressure. When the engine is started there is a massive cloud of smoke and steam/water vapor exiting the tailpipe. Did a cooling system pressure check and lost 7psi in about two minutes and did verify the leak by using a hose as a stethoscope. I heard a hissing/bubbling sound while listening at the oil filler on the valve cover. I did not hear any sound from the cylinders by listening at the plug holes or at the air intake with the butterfly open. I am guessing the most likely cause is the intake manifold gasket leaking into the crankcase. Am I on the right track or could there be another issue I am missing, I don't want to do any work that isn't necessary.
Your on the right track ,but i would go ahead and change the head gaskets also
