What are people using or like when it comes to valve stem seals? I see OEM which feel kind of hard, and after market "Viton" by say cometic or jims, etc. are more pliable?


Seems the softer more pliable ones with the tension spring would be better at sealing and longer lasting than the OEM ones?


While my top end is apart, just want to get the right ones. What do the guys who do this on a regular basis like to use? YD

 

Considering how long the Stockers appear to last... Not a Contest for me... O.E.

 

I don't do this on a regular basis, but at around 95k I had to re-lap the seats -n-valves on my '86. With the valves out, I changed the seals with OEM. So long as they were new, and not NOS I was confident in putting the OEM valve seals in. I made sure they were not old. The original seals were fine, but I didn't want to chance losing sleep at night so every gasket from the engine halves up I changed. No leaks, or smoke 50k+ miles later, and still running. Peace of mind has no price tag. Good luck------------------------------RJ

 

I just happen to have an extra set of Cometic viton seals in my lunch box. Why, I have no idea but if you pm me your address you can have them. I'll pop them in the mail... Free.. I believe they are amongst the best out there...

 

I've used the OEM in 2 rebuilds and no problems ...

 

I will take you up on that generous offer...many thanks and PM sent

Question: Is this the right tool to install the seals? I have read about guys using a socket, but...

^^ Plastic Thimble lookin thing is what we have!! Came with ??? Some guide seals at some time...

 

when using the installer don't just * smack* them down///you can with good amount of pressure push them on...or a good tap* not too hard..

 

Sounds good! Thanks!
