Valve stem oil seal removal and re-seating valves


Recommended Posts

Don't say give it to a machine shop, I wouldn't ask if I didn't want to do it myself :)

Anyway, what way do the seals come out ? I'd imagine they lift up with a pair of long nose pliers or similar but they seem fairly firm when I tried that. What's the best way to do it ?

- I have the valves & springs etc. Out of the head just need to remove the seals

Also, when reseating the valves, will I grind them in using the old seals or new ones or is it irrelevant ?

Many thanks in advance,

Regards

You should be able to give them a little squeeze one way and then the other with the pliers and then wiggle them out. You'll get it down after a few.

Or they do actually manufacture special pliers specifically for the job.

Seat the valves either way, I lubricated the guide and seal when doing so.

I've bought a valve lapping stick, I've read it's not the best to do with a drill

I've lapped in valves loads of times by hand its a cunt of a job but has to done, if u get good at it 5min to 10min per valve should do it, use the corse paste first then the fine stuff, u will see a good even shine all the way round the valve seat when done, its an idea to check them with petrol when fitted as wel,

They've been seated.

Intake valves tool about 7 mins each start to finish as they were in pretty good condition anyway.

Seated V non seated

On the other hand, exhaust valves took about 15 mins a piece becuase they were quite badly pitted. I ended up doing 2 runs with coats and 1 run with fine.

As before, seated V non seated

Took about 2-2.5 hours in total and is quite therapeutic once you're properly set up for it haha :p
