Question about Dometic Rooftop RV Air Conditioner
What causes a valve tap noise upon start-up of a cold engine--Chevy 7.4 liter Vortec?
Sticky lifters... I had a similar problem on my chevy 350. One quart of Marvel Mystery oil took care of the problem (2 weeks after use).
if that doesn't help, perhaps try some slick-50. The object is to make the lifters free themselves a bit.
