Well I have had some problems with my psd and i finally broke down and took my truck in for a compression test, due to the fact that i was blowing white smoke out my stacks, and burning oil. Well after it was all said and done, i have one cylinder at 190 psi, 3 cylinders around 280-300, and the rest just over 300. So basically my engine is shot. Does anyone have a complete 7.3l motor to sell? I cant afford the 8k to get mine rebuilt.
