Pulled the motor on my 2.8 Monty SWB today. She started loosing power and the other day wouldn't start. Ran a compression check and had 40 lbs on #1 and 0lbs on #2. I think the timing might of jumped. It looks like the fuel pump gasket was leaking oil and the head gasket as well. I haven't got it on the motor stand yet and haven't pulled the head to see what it looks like. Anyway, on E-bay AAAA Automotive it selling G54B 2.8's for $480.00 rebuilt. They list them for 1981 - 1984 monty's. If things look bad will this engine work with my 1988 with 5 speed or do you think I should redo the head and reinstall? I would like to swap in the turbo or a GM 6, but don't have the time to do it right now.
