A friend is telling me that iam risking that a cam bearing may fall down when taking out the cam cuz of the mileage that my car has? It has 182k miles and I don't think cz of the friction it may be stuck real good! Anybody got any issues like this or he just over exagerating?

if the cam bearings come out doing a cam swap than you definately have other issues. he may have been slightly confused, during a cam swap you definately have to be careful to make sure the LIFTERS dont fall down.

I think your friend means the lifters can fall down, yes they can.

just use pen magnets to hold the lifters up for cheap insurance

I know that lifter can fall down I already did cam swaps like 6 times but newer trucks with low miles and my friend told me that the cam bearing can fall down into the oil pan with like if u had to many miles and iam like I don't thinks so but maybe he is wrong or something ,thanks anyway!

you ever seen how cam bearings are installed? they are hammered in place with a special cam bearing installer. they aren't coming out.

I have yet to hear about cam bearing problems doing a simple cam swap....

If the clearance was so excessive that you cam bearings would fall out when you removed the cam you would have spun that bearing a long time ago. Cam bearings are an interference fit. If there is no interference then there is no fit.

if u have ever seen or removed and replaced cam bearings ur self, that answers your question!!! If a cam bearing falls out while installing a cam, u are using a bent cam and a BFH!!!!

Educate your friend that cam bearings are a press fit, and don't "fall" out. He must be confusing them with lifters (I hope).

I would poke fun at this but if I did I would be the first human in history that had a cam bearing fall out while doing a cam swap. Not possible I know, but thats my kinda luck.

would of the worst mechanics, and stupidest most full of **** people i know works at a dealership!!!

Yes a cam bearing can fall out, however it happens with low oil pressure and bearings that have already been spun, or an INPROPER install of a prior cam. Use a pen magnet for the lifters and be careful, the bearing will be fine.

I belive with the high milage motors you are risking lifters not staying up in the retainer cups.
I just use a couple small pieces of brake line and slide in the holes ot hold up the lifters, has always worked for me.
