Oiwa Garage Tech Note
"You need to compress the springs to reach the seals, so this is head-off or specialist head-on work. Match the intake or exhaust side called out in the title."
Frequently Asked Questions
How do I know my valve stem seals are worn?
Watch the exhaust on a cold start or when you lift off and get back on the throttle - a puff of blue smoke with no external oil leak points to worn stem seals drawing oil down the guides.
Do I have to pull the head to fit these?
No - you can replace valve stem seals with the head on using a spring compressor and air to hold the valves up, but it is careful, patient work.
Should I replace this if it is not leaking yet?
If you already have the area apart for other work, fit a fresh one while the labor is done. Otherwise replace it once it weeps.
