Re: [Fot] Valve Lash While Engine is Hot

["MadMarx" <tr4racing@googlemail.com>]

I did a lot of measurements between cold and hot engine but didn't find any
difference except burned fingers.
For my part I set it cold. It might be a difference with an aluminum engine
but with a cast iron engine it seems quite constant.

Cheers
Chris

Betreff: [Fot] Valve Lash While Engine is Hot

My engine has a Paeco TR-6600 cam.  The cam card calls for a .014
intake/.016
exhaust valve lash.  A little looser than stock, but not by much.  I know
folks running larger clearances on the hotter cams and wonder if these
clearances may be a bit too tight.

That said, In talking with a fellow racer tonight who will remain nameless
(I
don't want to name him in case I get a lot of back "lash" from this
question)
he thought I should ask the FOT group if anyone has measured lash on a hot
motor after a race.  We expect it to be tighter, and perhaps there is an
optimum clearance we should be shooting for.  Just a thought in case my
valve
lash is too tight.

Appreciate your input..

Thx

Ty
