Lifter Guide wear... While doing some cam work on my car I noticed at twenty thousand miles the lifter guides had worn to the point that the lifter was very loose in the guide letting the lifter to turn a degree or so and if a cam change was tried with the spin it over method you would loose the lifter into the pan. A call to the dealership and four new guides were bought for a little over ten bucks.
Guys for ten dollars any time you have the heads off replace the guides. If I had done that the last time I had the cam out it would have saved me from having to remove the heads this time.
Ten dollars for guides verses ninety bucks for headgaskets.

Re: Lifter Guide wear... You could have just used magnets rather than removing the heads.
Anyways, I noticed the same thing. 20k miles and 4 cams later my guides are looser than a whor..er..well, they are loose.
Also, when putting those new plastic guides in, DO NOT TIGHTEN THAT BOLT DOWN HARD. You *will* strip the threads out of it at what feels like 15lbft. Very weak threads.

Re: Lifter Guide wear... They were loose at 20K? Damn, that makes me a little leary about putting a cam in without removing the heads. Yeah, I could do the magnet method and risk magnetizing the lifters...I thought I've seen guys on here put cams in at 70k and the lifters "stuck".

Re: Lifter Guide wear... I think mine were loose by 20k because I've had so many cams in the car with higher than stock lift, and I've taken it to 6800rpms a lot. Probably have had 10k miles of >0.550" lift on them.
Even still, only 2 of my 16 lifters wouldnt stay up.

Re: Lifter Guide wear... I just bought the magnets from AutoZone and they cost me about $2 a peice. That is very cheep insurance if you ask me. I have done several cam changes and they work like a charm.
