Valve Lash Adjustment: running or not?

[bitfactr]

Thanks for the response.

Sounds like the by far most important point is making sure the lifter is on the heel of the cam. I can see having the engine running would do this, but make the actual adjustment a bit more tricky.

The manuals (and some other soruces) describe doing multiple values at given crank position, but this sounds like the crank position will be very critical (i.e. being slightly off might result in having one of those valves not fully on the heel).

Your procedure guarantees the target valve is on the heel. Thanks for info. I picked up an underhood bump switch yesterday, so I think I'm good to go.

Thanks,
Dennis
