So I tried to set the valve lash with the engine running and I suck at it. I can definitely hear some valve chatter still. So my question is setting the valve lash cold. If I set the valve lash cold should I back down from .015 and .020 to maybe .014 or .013 and .019 or .018?

And one last check set the intake as the exhaust is just opening and the exhaust as the intake is just closing?

If you run a stock cam, the setting is .010" and .020".

Have you read the Valve adjustment procedure in the engine section FAQ?

You can actually run the engine until it's good and heat soaked at operating temperature. shut the engine off and run the lash at the hot settings instead of wishing at the cold settings...

-D.Idiot

If it takes you too long, you'll have to run it again until hot and do the remaining lash adjustments.

DI is absolutely right in my book.... There's no big sin in setting static lash, it's just actually a little faster ,easier and possibly a little more accurate to do it running when you get the hang of it.but the objective is an accurate setting, if you can't get that running then do it static.. Out of interest some aircraft engines run solid lifters and are obviously set with engine not running, and that's an air cooled alloy case engine. There are people who swear that engines must be lashed running, strangely enough not one of them would stick by that rule if it involves a spinning prop while your doing it!

LOL SlantSteve I like that. I can tell you I have not interest in loosing a finger/hand/arm/nose/ear or any other body part to a spinning prop.

I tried again this time with the flat style gauges instead of the angled ones and it worked MUCH better. I am pretty comfortable that they are close if not dead on. I found to valves a little on the tight side.

Dont try and control the wrench. Let your hand limp and go with it.

I always set mine hot and static. 10 min and the motor doesn't cool off much.

I have to say setting while running is not easy but I think i got it this last time. I do need a new valve cover gasket. Should I got victor reinz or felpro rubber?

yep i did... and had the socket come off and almost go into timing set... i just get it hotter then operating temp (210) let it heat soak for 20 minutes, then start and get to 210 again. then adjust

I used a ratcheting box wrench held on nice and tight. I also found it was best for me to keep to the drivers side.

I find it interesting that my grandfather was able to teach me how to do it when I was 12 and I had no problems with it, but you have to set the idle down to 450-500rpm, anything higher than that and you'd better be the Flash.

I guess I am the flash. I usually set the valves with the motor idling hot around 750 RPM. I have set the lash both ways, with the motor off and with the motor running, and I much prefer setting them with the motor running. The best tool I have found to set the lash with a running motor is an offset box end wrench. Like was mentioned above, grasp it loosely and let it bounce around in your hand. Still, be ready for some skinned knuckles unless it is a really long wrench.

I agree an offset box wrench would have made it easier. The wrench I have is a bit short and I smacked my knuckles quite a bit. I think the ratcheting made up for it a bit. I also agree bringing the idle WAY WAY down helped quite a bit.
