I meant visibly... Will you be able to see the lifter compressed all the way.

Click to expand...

prob not without the intake off..

Just loosen the bolts and start it,, if it runs better,, but not best,, loosen a couple of the next bolts a bit.. don't do this for very long, as oil will be flowing from the loosened bolts..

then you'll know the valves are/aren't closing sufficiently.. and spacers are/aren't in order..

It's an orderly process of elimination,, and relying on YOU to report accurately.. not just what you feel like doing, or guessing that this is so, or that should be okay..


hope it helps
