Ok well i have had some really tought times getting the old dowel pin out of the cam im about to put into my car, but finally had a machine shop get it out. I purchased a new longer one from GM and it a a little (maybe 1-2 tenths) to narrow. It goes in pretty easy and i was wondering if maybe i could put some JB WELD in ther to make it stay? good idea or no? I have to have the done by the weekend. Thanks

 

Go ahead. Some green loctite will also do the trick.

 

Is there any pressure on the dowel pin while in the car, or is it just a reference point for the opti?

 

By 1 to 2 tenths are you referring to .1-.2? or do you mean .0001-.0002? If its the first, I would not use JB weld, I would get the right pin. If its the second, you must have mic'd it and then just use some strong loctite.

 

Yes more like the later...i just used jb weld and it worked perfectly. thanks guys.
