Re: valves not adjusting
Thank you for all your input and help. I called crower, the dealership, mobil 1, and consulted with a couple mast tech that I work with... To make a long story short, I decided to switch from synthetic oil for the break in stages.(first 5k). After I did it stopped tapping and I have driven about 30 mls and it's good.
this is what crower had to say.
Crower does not recommend the use of synthetic motor oil in any application, particularly in hydraulic and flat tappet camshafts. If your car manufacturer's owners manual suggests running synthetic oil, you may do so. The minimum gains in horsepower are offset by the excessive wear to cam and lifter surfaces. We have found that the benefits, of synthetic motor oil, do not outweigh the costs and may endanger your engine's life. Crower recommends a non-detergent / race only petroleum based 30wt. motor oil in all performance applications. The lack of phosphorus and zinc in current oil blends is catastrophic to engine longevity. For all applications we do recommend running our ZDDPlus additive, which adds zinc and phosphorus back into the oil. For additional information on oil, click here!
