Here is a question for the flat tappet cam guys....

My last cam failure was after a trip to Southern CA and back, a 950 mile run in 4 days. The freeway driving was the majority of it at engine speeds around 2000 rpms. Unfortunately, several months before the trip I switched from Valvoline VR 1 to this....

I was told after the failure that this oil was likely the cause. Synthetic emissions friendly oil with HIGH detergent. I saw the "Extra ZDDP" and thought it would be great. The detergent surely prevented the ZDDP from sticking anywhere, leaving the cam and lifters with no additional protection at all.

440-6, Lunati voodoo cam/lifters, stealth heads, using Brad Penn oil/Wix 51515 since breakin (2011). Recently experienced cold startup rattle, suspect one or more lifter bleed down. Starts right up, runs good, pulls hard. The uncertain quality of todays lifters has kept me from pulling the intake to replace them.

I always used Black Moly Extreme Pressure grease on the lobes and lifters.

That's good to know Kern Dog. On the RAM 1500 forum, the go to oil to prevent the dreaded Hemi tick, is Redline 5-30 Synthetic. Granted, the 5.7 Hemi is a different engine, but I'm not going to pay for it for my 5.7.

Somehow I missed the Hemi Tick with my truck. I’m at 414,000 miles and aside from a slight tick when cold, (broken exhaust manifold studs) the truck is quiet and still idles like new.
