Hello H-T,

I'm getting ready to rebuild my B16 head and
I acquired some Fel-Pro Valve seals. I have read
something about the seals being the same size ID.
I would just like to know if I install them, would I
run into any issues with them leaking ?. Supposedly,
Helms states the valve stem seals from honda have
different colored springs around the seals (white/black).
They also state that the sizes are different about .001.
Anyone that might have had exprience with these Fel-Pro
seals, kindly shed some like on this topic. It would be greatly
appreciated.

typically intake and exhaust seals are made from different compounds. and I have no idea what compound felpro seals are made with so I can't really say 100% how well they'll do. the 0.001" difference in ID really wont make difference though; if you measure the hole size before install, it's usually 0.010" smaller than the valve stem anyway. 0.001" is not going to make any considerable difference in tension.

you'll probably get a lot of debating happening here over felpro, some like their stuff, some dont. I've used felpro valve seals before on a stock honda and had no issues for the 50k I owned the car.
personally though, I do recommend supertech valve seals over any other brand, whether it be for stock or performance setups

 

Thank you dearly, that's about as good as it can get.
If they lasted you 50k miles that should definitely be good
enough until I can pick up a few supertech seals in the future.
Once again, thank you motoxxxman for the feedback.

anytime, yw
