It isn't so much the actual compression, as it is the variation between cylinders that is worrisome. Recheck after the carbon removal treatment. Compression needs to be checked on a warm engine, with the throttle held wide open for accurate results. Just a side note, my '01, which was abused, neglected, and left to die in a barn, now has 68,000 miles on it and no oil consumption, at all. 36k is still break in mileage!

- July 11, 2012, 21:40:50 PMSo my 1500 is drinking a little oil and puffs a bit of blue smoke at start up sometimes, so I was thinking valveguides are getting worn. Well, I did compression anyways and I got 105psi and 130psi on the front and rear cylinders respectively, with two different gages. Since I believe the max is supposed to be 85psi, I'm wondering if either the top end isn't stock or if the compression releases aren't working out? Has anyone had any experience with this? Can't decide if this could effect the oil consumption.
