[Healeys] Adjusting Valve Rocker Clearance

[Greg Lemon]

I have never had much luck with the "bump the starter" method, too 
imprecise, but I know many use it, so you can try, if you are not 
comfortable with it you can pull the plugs and push the car, it doesn't 
really take that much space to roll it, but if you don't have enough you can 
roll it back to the car starting point and use the starter motor to get the 
engine to a different starting point.  It is easier to roll in 4th gear, but 
will take more room to go through the valve cycle.

The claw thing on the front of the crank bolt as you surmise is for a crank, 
but since there is no hole in the radiator for a crank to go through (Early 
TRs had the radiator hole as a bit of trivia) it is not much help.

I am not as familiar with the 6 cylinder cars, but there probably isn't much 
room to get a big wrench in there on the crank bolt without taking things 
apart.

Although I have never tried this I suppose you could also tighten up the fan 
belt beyond normal and try turning it with the fan (that is how I always do 
it on cars where the fan is hooked directly to the crank), but you would 
have to remember to loosen it back off to save your water pump and generator 
bearings afterwards.
