<VV> CAM WEAR

[Paul Fox]

Group, You'll hear valve clatter first. You can adjust it out but it will come right back. I've rebuilt 5 engines so far with this problem. 2 of them I had to eat. At this point I will not warranty any engine that's not using at least 1000 ppm of ZDDP in it. More on engines with high spring pressures. You must be careful with your oil choices now adays. If in doubt add a container of ZDDP Plus. It can save you much grief.         Paul Fox--- On Sun, 2/27/11, Michael Kovacs <kovacsmj at sbcglobal.net> wrote:

Good thought, I guess I never had  a badly worn cam. But observing the lift of 
the push rod is certainly a way to be aware of a problem..

any motor that i have encountered with enough cam wear to show up in  
running , you could just about see the rocker arm not moving as much as the 
rest  

of them.  just went thru this on a "ran last year" motor i got running  
again before tearing it down.  watching rockers with motor running showed  one 
not moving as much as rest , without measuring it...that cam will now be a  
hard luck trophy someday.
