I did a compression test on my 01 with 157k miles the other day.
There was only a 5.lb or 2% split between all the cylinders, very happy with that. Trying to find some poop on good compression numbers.
I got 380 psi low 385 psi high, I think they are good for a truck with this kind of mileage. Can some one confirm this? Also is there a good article or old post about this subject. I can't figure our search engine on this sight to save my life. Thanks
