RE: Valve train noise
By Gregory Westphall - 08/20/2003 11:21:13 AM; IP 12.158.13.35
Well I may have answered my own question. After doing some research on the webv I stumbled on a Crane Cams site which explains that for cold adjusting valves with an iron block and aluminum heads you should subtract .006" from the recommended lash. Then, when the engine gets hot readjust to specification. This contrasts with the iron block and iron head combination where you add to the lash number when cold adjusting. This explains why I have little to no valve train noise when I start the engine up cold and then notice the noise start to appear as the engine warms. I found that the engine was cooling down while I was adjusting the valves because it took me too long to get the valve covers off. I sectioned some valve covers and removed the brake booster (1969 Cyclone) to assist this process. I also reduced the lash from specification, which according to Crane is perfectly acceptable within limits depending upon the type of camshaft. Also, I may have been adjusting the exhaust valve a little too early. They recommend that the exhaust be adjusted when the intake is 2/3 of the way closed. I was adjusting the exhaust when the intake was just about fully open. Engine is still running great with just the typical valve train noise one would expect from solid lifters. Installed the Edelbrock Rocker shaft studs last Friday. I now have much better peace of mind. I have pulled 2 heli coils out in the last 5 years.
This thread, so far...
