Cams and clearances
Looking for Cam bearing and cam to lifter clearances etc., I'm not finding any information on this.
First I am getting some tapping not bad but none the less it was there and after Thstone incident this summer I don't want to let it go. I rebuilt the bottom end plus valves, valve springs, retainers etc. in the winter of 2012 to 2013. The top of the heads was pretty much just reassembled.
Is it OK to put new lifters into a used lifter cage. is there any clearance spec?
Is there a clearance to check between the head Journals and the cam bearings?
While checking lifters to cams is there any clearance minimum /maximum?
I noticed most of the lifters spring back to being pressed 2 don't. My guess would be these 2 are my tap. 4 other don't seem to depress as far, but still compress and then rebound.
Any thought or experience is welcome?
