[DML] Re: Cam Wear cause (PRV Internal Vacuum)

["content22207" <brobertson@xxxxxxxxxxxx>]

PRV does run more internal vacuum than a traditional domestic block
(see Workshop Manual Page D:06:03). Listen to the thing groan when you
plug the breather hose with your finger tip. You can also bog it down
or kill it by spraying carb cleaner through the passenger side access
plug in the timing cover (immediately processed by the intake).

I do not recommend running an engine with the valve covers off. Once
adjusted valve lash that way on a stud mount 460. Will never do it
again -- makes an ungodly mess all over the driveway.
