Hi all,
Head and barrel now stripped, the plan was a thorough clean and paint, but I have come across a problem, the exhaust valve guide was loose with about 1/8" play up & down.
I made a drift and knocked the guide out, after the initial play the guide was tight in the head.
When the valve was put in the guide it is "sticky" at the point where the valve would have been in its seat.
New valve and guide obviously required, but I am unsure what to do to make sure the problem does not reoccur.
New guide with Loctite and hope for the best? Can you buy oversize guides (I remember doing that to a Triumph years ago) or will the guide hole need reaming and a guide made to suit?
I'm a bit stuck on this one, and as ever any advice is really welcome.
Cheers
Chris
