1996 GMC Yukon V8 Four Wheel Drive Automatic 126241 miles
I started the truck this morning (really cold) and the truck made the normal ticking. It usually goes away about 3 seconds after startup. But this time it stayed. Checked the oil. Fine.
40 LBS of oil pressure the ticking is from both sides of the motor on top (valvle cover). Do you think it's a lazy lifter? Would Marvel Mystery oil help?
have the same problem?
