Exessive cam journal clearance

2 posts in this topic

1987 2.0 has cam journal clearance of around .003-.005" after installing a new cam. The factory service manual says this is about the limit. Is this a common situation for these engines? There is visible wear on the head where the cam rides, and on the old cam. I'm wondering if that was what caused low oil pressure and spinning a rod bearing before I rebuilt the engine and found the high clearance. Engine only had 43,000 miles on it.

I don't know much or rebuilt the engines on the 1987 626. From my general rule, if there are any excessive clearance on any part of the motor such as the cam clearance and or Main bearing journal oil clearance; its most likely going to cause low oil pressure. Don't forget to consider the possible oil pump failing as well.
