On the 2000 4.0L, I know that "anything above 100PSI is ok if all cyl are more or less even" But I cant find any data that says what new/rebuilt '"normal" should be.

If I come across a good deal on a parts truck I's like to know what is "normal" from the factory to have some point of comparison.

Also when I comp test the engine I have soon, same deal. I'd like to know what new normal is/should be just for reference sake.

Thanks!

 

around 165 psi.

 

Thanks!...
