Opel Rallier since 1977
So Carl, just use the numbers that you have been given by Gil; I would expect him to know the right lash settings. Don't let me confuse the situation!Wow, now that is really great information for a first time valve adjuster like myself and makes a lot of sense and better than that makes me feel more confident knowing I won't fry the engine. Between you and Manta Rallier I will soon be an expert. Thanks, Carl
And as far as lash variation between adjustments, that is not unusual. The rockers seem to take slightly different 'sets' on the rockers pivots and valve tips when you rotate the engine slowly by hand, and that causes the variations. But small variations like .001" or .002" are not important, IMHO.
A 'hot and running' lash procedure will get all around that, but these Opel engines tend to fling oil all over the place when idling with the valve cover off! (Ask me how I know ... ooops... 'clean-up on aisle 9' LOL.) It is not a problem on something like a Mopar 225 slant 6 engine, where the oil supply up on top just dribbles at idle.
