thats not really true, you should do the leakdown test first time with the motor exactly the way it was when it was run and said issue discovered. it would be pretty silly to take a bunch of shit apart right off the bat just to discover a pushrod was too long, or a valve way out of adjustment... things that would readily go unnoticed in a quick tear down of the valve train. but yes after you nail down the afflicted cylinder(s) you may consider removing parts of the valve train to assure they are not the problem. though a quick wiggle of the rockers will usually tell ya whats up.

those of us that know how to do one will do that already before doing a leakdown test...but you are right.

i was merely assuming that someone had already checked out the lash while at base circle.

of course, this being a valve damage question, it is safe to assume that the actuation side is already taken care of and out of the loop.

and of course, i was saying take the cam out cause 99% of the tech issues in this forum have to do with a honda :shudder: and that is how you rid the lash on most of them (you can back off the lash adjusters, but most of the time thre is already damage, and you might as well start tearing down. takes the same amount of time too )
