My 110 jester crapped out on me coming back home from the No Ga scouting trip.  After I retreived it and trailered it back home Brian Rose got to it today and opened her up.  Never would have expected this.  The valve guide on the rear cyl exhaust valve dropped down from the head at least 1/16" or more preventing the exhaust valve from closing.  And the intake nicked the edge of the exhaust valve and bent the intake.   

Most unusual as far as I know and especially for only having 23k on the clock.  All I can figure is just a material / assembly failure.     Doesn't seem to be related to the well known 110 problems, but Brian did tell (and show) me that the cyl liner is again shifting.  You can feel it every so slightly proturding above the cyl itself.

If I have time I'll get by there and get some photos.  Didn't have the camera with me this afternoon.

Ultrafxr,

The shift is so slight I don't think a photo will show it but I'll try.

Jerry, this isn't the first such incident among the group here.  Thought I remembered more than the following citations but these were what I could find:

If he'd be interested in this thread and might accidentally miss it I'll PM him with a link here.  He'll be sure and find it that way.

I missed those threads and was unaware of others having problem (and not all 110s either).  Don't know if my guide is cracked - that might explain why it 'dropped.'  Will investigate more.  Damn shame in any case.  Sould not happen.  SM is going to ask for new motor and I sure hope we can get it.

Good news is bottom end looks OK.  When Brian found the valve problem he pulled the cam chest to check everyting down there also.  All looks real good including oil pump.  So looks like my runout is OK or we'd see some signs of wear after 23k for sure.

Jerry, it sounds like a Hobson's choice.  In your case I'd find it a hard decision rather to push for a new top end or a new engine. 

You know (as well as you can) that your bottom end doesn't have crank problems.  That's a big deal.  You can't know a replacement won't.  I don't think anyone knows yet if that issue is fully resolved from the factory.

It's easy to understand wanting either solution.  A new top end on top of a known good bottom end, when so many bottom ends weren't.  Or a new motor at 20k plus to have and to hold and start over again.  My friend, I'm glad I'm not in your shoes on this one.

Yeah, I thought about that.  Trying to convince myself it'll be OK if we just do the top end.  But on the other hand I'd just like to start over fresh and all.  Either way it's a crap shoot.  Best wrench can still drop the ball on a rebuild and so of course can the factory on a new motor.  We'll just be patient and let it sort itself out.  Que  Sera, Sera

Will the SM be able to get an answer from God before the holiday?  Or will you be wondering until next week sometime?

[GMR-PERFORMANCE]

That is not as uncommon as you might think. The heads has a very loose fit on guides and valve seats. I have seen several that have been moving and a few that had dropped the intake seats out.  hope the dealer gets back up and running asap. I know I would be bummed out about it.

is this always on the rear? maybe heat related?

[nixobilly]

Ultrafxr,

Like a lot of people here, I had my head gaskets replaced at 9.6k.  Rear leak again while out on Nelson trip.  After returning home they went in to redo both head gaskets again and found rear valve guide missing entirely (exhaust port)  and replaced the head and put high tension head bolts in both heads.  Now at 27k the rear is leaking again in addition to using 2 quarts of oil (seepage is very light, no noticeable smoke during operation but that oil is going somewhere!)

I'm meeting with Service Manager and HD rep next week to discuss options.  I'll definitely request crank runout check.  I'll probably push for top end swap out assuming the crank looks ok.

Good luck with yours

Mark

SM left today for well deserved vacation with his family and won't be back until Monday.  In conversation with him late yesterday he indicated that he wouldn't be able to reach anyone at the moco anyway.  Probably best as they'll all come in Monday relaxed and refreshed and ready to make me happy.  Did I really say that?  Who am I kidding?  This is the moco after all.  Repeat the mantra:  Gotta think positive.  It'll be OK.  Gotta think positive.   It'll be OK.

Thanks for the info GMR.  I thought those guides were a pretty tight fit in there.  Like Dennis asked - is this heat related?  From threads Don referenced it is not only a 110 issue.  Is there a cure?
