Im sure it possible to change-out a guide seal while head is still in place? 

 

I designed a "special" tool for the purpose. 

A working prototype has been fabricated and tested...

🙂
 

I'd like to see it if you don't mind.

Wish I could...

I'll start a new topic in the Engine category after my cylinder #3 valve seal replacement is successfully completed.

New Viton valve seals are expected next week, at which time I will probably be set to dive in.

      I had a similar issue with my GPZ1100A1 engine, I had new valves fitted, seals etc, after w while I noticed a slight puff of smoke on de-acceleration, obviously the valve guide seal was suspect. I found that the valve guide on the one cylinder was slightly up compared to the others so the under bucket actually touched the seal. I used the compressor method to hold the valve in place made a valve compressor tool, used a b rass bar and "gently" tapped the guide down, fitted a new seal, no more oil consumption.
