rayaapp2 4 Posted June 5, 2011 So I need to replace my valve stem seals. Next week Ive got the time. I am looking at OE, which lasted a whopping 80K miles in my original RB25det. Thats okay, but not great in my book. What about Supertech Valve Stem Seals? Are they any good in anyones experience? More importantly am I restricted to using valve stems seals for a RB25 or can I use the RB26 valve stem seals on my RB25 head? Suggestions are welcome, Thanks Quote Share this post Link to post Share on other sites

rayaapp2 4 Posted June 8, 2011 I figured for under $40 to my door Id give the Supertechs a try. I just got them in, yes I ordered them for a RB25det. So I open the package up and find 2 stickers and a banner card. The companies name is IPGparts.com. Okay stickers, whatever. But then I see the card.

rayaapp2 4 Posted June 13, 2011 Im still looking for any insight you guys may have on valve stem seals. I will report back my findings with the SuperTech Viton seals IF no one has a known better product that I should try? I will be installing these this weekend if nothing changes.
