Which valve stem seals leak
I'm looking to replace the valve steam seals in my 2000 after noticing that it burns a bit of oil when revving it out, and I'm going turbo.
I looked on eBay, and found some Supertech valve stem seals (Supertech Viton Valve Stem Seals 1.6L 1.8L Mazda Miata / Ford Escort BP B6D MX5 | eBay), and considering the name, and the price I jumped right on them. I was watching a video on youtube ( This has me concerned that I just dropped money on some junk. Has anyone heard anything about these seals and whether or not they're any good? |
Most people will recommend OEM. Valve stem seals on the bp engine are a common failure point when non-oem seals are used. I bought supertech spring for my head during my engine build and they came with supertech valve seals. I used them and I am about to replace them with less than 3k miles on the motor because they are leaking.

I'm installing some in my VVT head that's currently being built. We'll see what happens!!
|
I had 2 sets of supertech valve seals leak on me. Never again. OEM works perfect, and are cheap.
|
Supertech seals leaked like a sieve here too
|
Well damn, now I'm getting worried mine will leak :cry: I wonder how fast I can get OEM valve stem seals shipped to my house.
|
I think mine are leaking too. Installed 400 miles ago.

Would you guys happen to know the part # for the intake and exhaust valve stem seals? I did a bit of searching and I think KL01-10-155 is the intake valve seals and KL02-10-155 is the exhaust valve seals. The price is $8.15 for the intake seals and $6.68 for exhaust seals. I'm wondering if that's the price per seal or a set? I'll most likely have to call and ask unless someone here knows.

The price is per seal |

Goddammit. Why don't you people speak up sooner?
My Stupertechs are leaking, was going to replace them with more Stupertechs this weekend. Fak. |
Sigh. I have a head in my garage with Supertech valve seals in it, too.
Feels bad, man. |

Also covered this in my build thread. Not even sure why I installed them because I had read other threads of people saying use only OEM. Read more noobs :party:
|
I thought supertech valve seals were known to leak. At least that has been what I have been reading for the last several years.
|
I'd like to hear from a couple of the forum vendors who supply them. The usual google search returns some talk of leaks but more of the "I run them no problem " stuff. A lot of instances with leaks also involve dual springs with the seal contacting the inner spring id.
There's also the installation of the intake on the exhaust and vis a vis that I doubt people are quick to admit to if they installed wrong. So I'd like to see vendors comments. |

I'd also like to hear what the vendors have to say about the Supertech valve seals. I mean if this was such a widespread problem, you would think that Supertech would look into fixing this with another revised version of the seal or something. I'm using these with both Supertech +1mm oversized intake and exhaust valves and the Supertech double springs. Not sure that would make a difference. |
scared of the Supertechs's, i used some Fel Pro's i had. Ill come back later with reports, good or bad.
