Viton Type 1 pushrod tube seals

[babysnakes]

After searching and calling a number of vendors, it seems like these are not made. Is this true? If not, where might I find them?

Naw man, the guy is just pulling your leg, or confused silicone with viton.
You want the SILICONE pushrod tube seals; those are the good ones, but remember nothing sticks to silicone.... except maybe silicone.... so don't put any goop on em.

I hae whatever white rubbery POS's that come in the basic rebuild kit these days.. They fit the tubes snugly, but once i torqued the heads down, almost all of them bulged out.. Do i need to pull my heads and fix them, how do you hold em in place? Last time i had the reddish ones and they didn't have thise problem.. :/

I haven't bought a gasket set in ten years. Almost nothing useable in them things. From what I remember the red ones crack and the white ones turn into chewing gum

CB sells the silicone pushrod tube seals and nice flywheel o-ring too.
THe empi silicone pushrod seals are good too from what I've heard

The white ones that come in the Elring sets work fine. The silicone ones from Empi are too soft.

we carry the Elring sets, they work great.

However, another problem we have seen is where the push rod tubes are too long, and they bottom out before the head is fully torqued down. This squishes even the best seals out. This is not a common problem, but we have seen it often enough to be aware of it.

Push rod tubes do come in different lengths, and sometimes it DOES matter.

First, put a tube in without seals and make sure it's not too long. The 1300, 1500, and 1600cc tubes DO vary in length, depending on the mfg. If all are too long use a 40hp tube and stretch it out, it will compress to the proper length after the head is torqued without squishing the seals out. Squished seals happen if the seals are too soft, or if the tube can't compress any more.

It's common for "higher compression" engines to need 40hp tubes, because the heads have been flycut for compression, making the engine narrower and needing short tubes.

With the spring loaded tubes, the spring is too stiff for the softest seals, the Elring ones work great. Silicone but are firm, not squishy.

Thanks John.

much appreciated John! These tubes are old(used for less than 1000 miles, but the engine has sat for 5+ years..) but still in great shape, but the heads are new, so maybe they are just fly cut..

I just figured out the riddle. Type-4 engines can use viton o-rings! aha!
