I tend to check the lash more frequently after a rebuild, like before a meeting. If you use the parts in the places they originally came from then I've found the lash settles down really quickly. Once they've settled I leave them 'till season end or 'till I break something and the pattern starts again.

I admit it might be a bit excessive, but I'm anal about that, and it's worked, so why mess? I've got 15 passes on this oil, and will probably change it after the Beaver Nostalgia Nats this weekend. As far as the valves, I go over them the beginning of the season and let it go. "Old age and treachery trumps youth and enthusiasm, every time!"

Ounce the valve train stabilizes they rarely move. ALot of times nothing gets adjusted, just go in and check and make sure all is good in the hood.

Big spring pressures should be looked at,might as well check lash. SS/AH guys do it every 3-4 passes. 5340964-mopar_resize.jpg (31 downloads) The little old lady from Pasadena is back!

Valves, once at the begining...then again if if starts acting or sounding weird. 67 Barracuda street car, 408, e85, 1.38 60', 6.44 @105.9 in the 1/8 mile, 10.19 @130.5 in the 1/4...so far....

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. "I am not ashamed to confess I am ignorant of what I do not know."

If I race a lot, I will change it again during the season (50-60 passes). I check the valve lash every couple months, but it doesn't need it. A new build requires checking it every race day until I am sure nothing is changing. 1993 Daytona, 5.50 at 130mph (1/8) 1.19 sixty ft (PG). Link to 572 B1 - Part 1

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.

Like most things the more power or rpm's the more preventative maintenance. Roller cams will need less checks than solid lifter cams. Some guy's will get more junk in their oil buy pulling the valve covers causing more problems than if they didn't do anything. I change my oil with every oil pan replacement. it's ok to butt heads, just don't do it with a butthead
