ok so i recently blew my stocker in my 97 and bought another 4.0 out of a 94 for 175 bucks to replace it with. it had been sitting for 2 yrs on a pallet in a garage so it was a mystery buy but i took the chance. i pulled the valve cover and oil pan and its got some nasty sludge build up. i then decided to compression test it to see how the rings are. i spun the motor over with a ratchet and socket 5 to 6 times each cylinder with the tester in each hole.
the oil pan was still off and it sounds like air is leaking bad around the pistons and seaping into the crank case.
here are my results..
1-45psi
2-60psi
3-40psi
4-10psi
5-40psi
6-40psi
these seem extremely low but im curious if they are just low because i had to turn the motor over by hand.
let me know what u think and if my rings are garbage or this seems ok
thanks :cheers:
