smog shop did a compression test on my truck and said i have an issue with #2 @5psi and #3 @20, the other two cylinders been @125psi , said something about valve adjustment might be to tight or a head gasket the oil is clean and there is zero smoke coming out the exhaust. the motor was rebuilt last year by the previous owener and of course the warranty does not transfer...

If the valve adjustment checks out, you're gonna have to take it apart.
