I'm using Hughes roller lifters and
roller rockers on my 360 . they say to use 10w 30 oil only I've always used royal purple XPR10-40 will I Damage the lifters using the 10-40 or will it be safe to use once the engine is broken in ?
Anybody using these lifters with oil heavier than 10w-30 ? okay I'l play find a photo this good enough?
