Hi Guy,

Some valves rotate by the fore and aft position of the lifter against the cam and others use a mechanical 'rotator' up near the tip of the valve where the retainer is.

This is what they are asking you....Does the valve use a mechanical rotator or is it just a plain valve, spring and it's keepers riding via the push rod down to the lifter which in turn is actually doing the rotating.

I know that sounds clear as mud.

Look down the lifter bore...if the lobe of the cam seems to be off-set (front to back) to the lifter bore, then you probably don't have a mechanical rotator. The cam lobe is 'turning' or 'spinning' that lifter as it lifts it.

However, if the lobe of the cam seems to be directly in line with the lifter bore, chances are the engine uses a mechanical rotator.

Boy!! That is hard to explain!!

The valve has got to rotate either way; if it always landed in the same position, it would soon become out of shape and burn.

Well, I tried,

Allan
