Cam Bolt Question
I am trying to find truth in an argument I am having with someone.
If you didn't remember to put loctite on the cam bolts, would those bolts start to back out after a year of driving or would they come out pretty quickly?
If those bolts were loose, would you still be able to start the car repetitively and even drive it?
TIA

My question would be, why even chance it? That person that did that might want to consider going back into his/her engine and putting the locktite for the added insurance of not having to worry about the cam walking back...

The situation is in the past, and it is alleged. I am just trying to find an answer to those specific questions.
Thanks for your time, though.

I've done the install several times with no locktite and everything was fine. Its probably more likely they will back out, but its not a black and white type of issue. It could take anywhere from a day or two, to 10 years, to never, to back out.
Forgot to add, more often than not (say, 10-15 times) I do it with locktite.

Yes, it is extremely possible. I've seen two engines ruined by the cam bolts walking out. One was done by a sponsor. It can and does happen. The torque specs from GM are not suffecient. Either take them to 30# or loctite the hell out of them. I loctite and overtorque. Once you pound the lifters out of the block with a hammer thanks to the cam moving like Katherine Hepburn in a paint shaker, you start getting those suckers tight.

ZaneO, Please don't delete threads on the board when you are done with them. Maybe next time somebody wants to ask something similar, they can find it in a search.
