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.

Why would you take a sellers word over the experienced people here?

Yeah, but Cardinale Mazda is a bunch of dickbags. There use to be an awesome guy over there named Frank (IIRC) who would hook a brother up with MazdaComp pricing, but he left a while ago. :-(
+1 After you buy 100,000 seals in a production run, you tend to continue to sell them until they run out, regardless of how much they suck. Then maybe they get revised. Maybe ;)

Supertech isn't making these... They aren't just going to "make a new run."

Now. If we can figure out what other applications fit, like a Kia or Nissan or Ford or something, we can probably find these without the Mazda tax. Just so long as they don't turn out like those Ford oil pump seals, we should be good. |

Unless they leak because they are from a Kia or something.

Yeah, they probably fit some other application and they just bought them in bulk on the cheap.

You're going down the same exact path that got you to leaky Supertech seals. :hatecat:

I thought everyone knew supertech valve seals were fail and aids.
My felpros worked just fine, ryan. |

So it looks like 949 Racing offers their "super miata valve seal", which come from the same supplier for fel pro according to the their website. Supermiata Valve Seal Miata
However while researching on this, I found a thread from 2015 on M.net where someone recommended supertech seals from 949. This is the link that was posted. 949 Racing - Supermiata (http://949racing.com/supertech-valve-seals-miata.aspx) The Supertech valve seal link from 949 is dead now so it seems like they used to offer the supertech valve seals before, then switched over to their own seals which come from the same supplier as felpro. Also TSE sells the Supertech valve seals on their site. Supertech Viton Valve Seals I wonder if Andrew has had any issues with them? Hopefully he can chime in with his opinion on this. |
Had Supertech valve seals from 949racing on a fresh forged engine.
It was burning oil and I couldn't work out why. Pulled the inlet manifold and low and behold every valve had oil on it. Fitted OEM. It's spot on and how it should be. From inspecting the supertech valve stems they are slightly bigger hole compared to OEM. I've had 2 other friends have the same problem! It just pours down them. Wouldn't touch them ever again and I always tell people to go OEM. |
Mazda lists 2 different valve stem seals for the 1.8L. Following is a crossover list (including dimensional info, vehicles and part ##) from S.B. International who happens to supply a lot of OEM and aftermarket valve train parts.
Intake: KL01-10-155 KL10-10-155 Intake valve stem oil seal cross reference Exhaust: KL02-10-155 (Supercedes B660-10-155) KL02-10-155 Exhaust valve stem oil seal cross reference B660-10-155 Exhaust valve stem oil seal cross reference Enjoy... |
Meh. I put supertech's I ordered from 949 on the head I just refurb'd. We'll see how they do.
I remember being surprised that they were color coded, but the colors seemed unintuitively backwards: like the blue ones go on the exhaust valves and the brown ones on the intake. From a human factors design perspective, it seems like you'd want it the other way around. I'm curious whether the root of the problem is that either they got the part numbers switched, or people are putting the blue ones on the intake by mistake. |
They physically fit in both locations, and for a while now people have been installing the supertech exhaust ones on both sides.
In fact, this is what I was told to do by the vendor who sent me the set of supertechs that's sitting here next to me on my desk. https://cimg4.ibsrv.net/gimg/www.mia...812a70eed2.jpg Notice both sets are blue. But this begs the question, are people installing the supertech intake seals on the exhaust and they can't handle the heat? |
Mine are already leaking. And I haven't put much heat into them a all. Seriously doubt that's an issue.
Especially since my exhaust are the ones that appear to be leaking. |
