<VV> OT10 CAM , LIFTER NOISES

[Jack Kean]

Tim,

i had (and have heard that others too) 2 lobes completely fail on an 
OT-10 cam. Engine always clattered (I purchased it that way). I spent 
weeks playing around with the valve lash until one day the clatter 
become more than I could stand. I torn down the valve train, after 
measuring that the lift on 2 lifters was far (I can't remember the 
actual amount) less than all of the others. You could see the wiped out 
lobes with the heads still installed, looking through the cylinder 
heads. You just drained the oil. Any metal shavings in it? Check the 
lift on the 2 offenders before you go any farther. Look at the bottom of 
each lifter after you remove them. My guess is that it will be not be a 
good sight to see.

Hope you do not have to pull the entire thing down and my guess is 
completely incorrect.
