Hi All!
I have a 90 MJ with 2.5L and a 5 speed. I paid $400 for it and drove it on the trailer. Previous owner says the truck has sat since 2016 when the radiator leaked out and overheated.
I started tearing into it today. Swapped a good radiator into it. Runs a bit rough but runs, drove it up and down the road - has decent power. Blows smoke out of the valve cover. The CCV system is fully operational. Did a compression test - #1 - 120, #2 - 150, #3 - 165, #4 - 30. I did the compression test with the engine cold. I added a bit of oil to #4 cylinder and still got 30 PSI. I'm guessing something is catastrophically wrong with cylinder #4. What says you all?
I would like to fix it if I can cheap. If not then I'll let the truck sit until I can find a decent SBC to swap into it.
Thanks for the help.
