Well you wanna talk anal I guess that is me. We check the lash pretty much after EVERY trip to the track. I usually run the oil for no more than 20 passes or so, never at the track but when we come back froma race and are in that area.



We have our valve covers off at least twice per race. A big lash on one valve means something's not right. We've caught early some pretty serious issues this way. Two races ago we had a tip come off of a titanium valve and the rocker had begun to eat into the stem. We got it before it became a BIG deal. Oil change? We take our motor apart several times per season so the oil get's changed then.
