I wouldn't let a dealer change a lug nut. Are you insane?!?!! Ok I let 'em do the last transmission recall but I know they could feel the evil eye over their shoulder the entire timeDid you ever ask your dealer how much they would charge to replace your valve springs, or would they want to remove the heads?
I think this will be a good preventative measure for those over 200k, seems the valve springs break, shatter the valve and it drops through the piston, then the rod doesn’t go up, it goes sideways through the block!
I agree and I will do mine soon (in frame), had I not already bought a stock set of 16 along with seals and a few retainers from Tasca I would have gotten an aftermarket set from @Cody Dawson with PAC springs and Ti retainers for a little more and pestered him relentlessly for tech support throughout the install haha! My current excuse is I need a beater car for grocery getting in case something goes amiss (if I drop a valve it's going to be a bitch to pull a head, the whole front timing cover and chains have to come off; I don't think that can happen if that hole is at TDC but there's always a chance I can F something up). Currently the Raptor is my only means of transportation so I need to keep scouring craigslist for a cheap backup Prius or something...
