RE: [ST] Re: Any High Mileage Sprints Out There?



I'm going to stick my foot into this one and hope it doesn't get bitten off.
The valves them selves aren't measured.  The distance between the Cam lobe
and the shim is measured.  The shim sits in a bucket which pushes on the
skinny end of the valve.  If it clearance gets to tight then I assume and
this is where I am guessing, is that the scavenging effect the exhaust pulls
oil up into the cylinder and thusly out the pipe.  That last part is a
educated guess so take as that and don't quote me.  Unless of course I am
right!!!

I would assume like an auto it is done at the valve seat. The other
question is are you talking about valve lash or valve seat? I am with
you on the other question, why do tight exhaust valves consume oil?
