When to replace valve seal?

Post by jeremysmith035 »

How do I know if my valve seals are worn?
The previous owner said the valve seals need to be replaced but I have not noticed it burning excessive oil since I have had the bike.
I burn coolant severely and plan on changing the head gasket to fix my coolant issue. However I am not sure if I have a valve seal issue.
How can I tell if the valve seals are worn?

Normally by the exhaust showing excessive white smoke on startup and not going away... If the valve stem seals are old and dry - they will leak oil past them and allow oil to enter the combustion chambers causing the white smoke.

IF you are replacing both head gaskets - it would be an ideal time to replace the seals - and more than likely service the heads and valves as required.
