Hello everyone, 98 GMC K1500, 5.7, 184K miles. My Truck runs well but has the annoying lifter tick. When I cold start it, it doesnt tick at all. After approx 10 minutes and the engine temp starts getting to 175 or so the tick starts.
Im 99% certain its not a leaky exhaust gasket. Sound is coming from center of engine and well, under the intake. Pretty much where the lifters sit.
I'm thinking of running Marvel Mystery oil through it and then trying a heavier oil.
I live in utah so winters are cold, so I was thinking a 10W-40? Does anyone know if a 5W-40 Diesel oil will hurt anything? and what exactly is the difference between diesel oil from gas engine oil?
Any other suggestions? Like I said it runs good but is just an annoyance with the tick, tick, tick at stop lights and in parking lots.
thanks!!
