I had a pushrod collapse on me once.

Ever had a valve adjuster loosen in flight?

Yup - and the fact of it could only be attributed to operator error.

Yeah, "collapsed" does not mean the same thing with these solid lifters. "Shattered" is a better description of some I've seen.

I was teaching my son the work on his

after a good instruction on valve gap during the check out ride my son has one of the adjuster come loose and loudly sound off

Ah forget to tighten a nut I say

son: No Pop I tightened them

Pop: so remove the left cover ah ha there it is bring that cylinder to top or OT in the window and adjust it again this time tighten it good

after that he'd call before he'd come home to have his bike ready........

If it "broke" there would be no doubt about it.
Period.

Investigating under the valve cover, I found 1/8" or so clearance on the intake valve.

I normally try not ham-fist the adjusters to avoid stripping, but I guess I need to put a little more torque on them. Re-adjusted and torqued them all last night.

I guess the main question still is....was the nut loose when you checked it and found all the play? If the nut was tight you've got more seriuos issues......or the valve was adjusted with the PR tube out of alignment with the lifter. The 1/8" of clearance suggests this to me.

A lot of good theories about what happened. Fact is it, just loosened and nobody to blame but myself. Was just asking if others goofed like this before.

A lot of truth in: "Familiarity breeds contempt"

No collapsed lifter, no collapsed pushrod, the adjuster was loose.

As I said, rechecked all 4 for gap and nut tightness, runs just fine.

With trashed lifter, I'd be running on one cylinder or runny crappy.
I pull the pushrod even before my original post and it was ok
I even changed the oil and filter ( due anyway ) to look for metal chips....none.

Nice to know this "happened" to others.

Thanks all and sorry for using up bandwidth on this
