When started cold lifters noisey oil pressure erratic, stabilizes after a few minutes, and lifters quiet down, after oil change everything normal. Till 1500 to 2000 miles. Truck performance not effected. Hard to tell if oil is contaminated by site. Is this common problem for this truck. Leaking injectors after turning off truck. Leaking intake manifold. Like any troubleshooting help.

Use a fuel pressure gauge to see if it looses pressure while sitting witht the engine off. If it does, block the return line and see if it looses pressure again. If it does take a look at the injectors for possible bleeding down
