Valve Seal Replacement

Post by Grindl » Thu Aug 23, 2018 3:38 pm



Okay Motor-heads .... I'm contemplating changing valve seals on my 83 1100-A , without removing the heads from the engine . I have been doing all of my own engine work on my Wings for roughly thirty-eight years , including total rebuilds , and have fifty years of motorcycle engine experience .

The reason for not pulling the heads , if possible , is simple . Cost and time . Cost of the head gaskets , plus wait-time to get OEM gaskets & O-rings , etc. from dealer . Along with the fact that the heads were just pulled a year ago , and a complete valve job with new guides / seals , was done at that time .

Now getting a very light amount of wispy oil smoke , that is equal from both pipes at idle after normal ( 3-5 min ) warm-up , and it is constant . I've seen this problem before here in Az. , mostly caused by our summer temps . Vale seals would get hard , and start leaking . Back when parts were much cheaper , the "fix" was just pull the heads and replace the whole works . Now ; with a set of head gaskets running over a "Bill" , not so funny ....

So ....Any thoughts , suggestions ? Anyone ever done this job before that would have insight or solid tips to follow ?

Put a cotton rope down the hole. Turn the engine until you feel the piston stop. You can remove the seals and not lose the stem down the hole.

+1 on what Wilcoy02 said. It's the oldest trick in the book and works brilliantly. Just remember to leave enough rope hanging out of the spark plug hole to be able to retrieve it when you're done!

You just did it a year ago and thinking it needs valve seals already? It ain't that hot and dry anywhere on this planet.

Appreciate the good info for holding the valves in place . Thanks guys ......

@ Dave 0430 ...Don't know if you've ever been to Phoenix in August , but it was 109 here in Peoria yesterday , and at 2:30 p.m. , the pavement temperature on Grand Ave was 178 degrees . Concrete roadway . We constantly have "News" blurb for the STOOPID on TV here , not to walk your pets in the afternoon without protective boots , and even the smallest kids who play outside know not to step on sidewalks in the afternoon . Just accepted part of living in the desert . You've never seen any of the videos of frying ham & eggs on the sidewalks here in Phoenix ? They are on YouTube .

By way of understanding the problem ; My wife works 18 miles from our home , and it takes her on average , 45-50 minutes driving time from work in the afternoon . Think about making that trip at the hottest part of the day , basically light to light , stop & idle for five minutes , go to next light , and wait , idling for five minutes . And the next , and the next .....BTW ; the Temp gauge went into crisis therapy yesterday . Yes Dave it does get that hot here . Try it some time ....IN AUGUST !

I'm sure it does get hot but the engine runs in the 210 to 220 range when it getting up close to the red zone.

Thanks for all the replies . Appreciated . Had to order the 1/2" rope , but it worked , swimmingly , lol . No more wispy oil smoke after changing the seals . The lips of the seals I took off were crispy and beginning to break away . Took them to the local "Stealer-ship" parts dept. and they concurred that they were defective , for what-ever reason , and no one there had ever seen this before , either . Of course ; The first question I was asked was , "How often do you change your oil" ? The answer is ; Every 3,000-3,500 miles , and I only use the same oil in this wing , that I've run in both of my Wings for forty years . Castrol 20-50 in the Summer , and Shell Rotella 15-40 in the winter . And the filter gets changed every oil change . That's a rough total of over 1.3 million miles , so I guess even Goldwing parts can be defective . Changing the seals was a minor pain in the butt compared to having to pull the heads , radiator , carbs , etc..etc..etc ! Sometimes "Chit" just happens .
