pushrod tube seals with teflon thread sealant, how do you apply it? Options

[Cap'n Krusty]

I've used motor oil from the get-go, 40+ years, without a significant number of problems. Jake does a lot of engines, and the conditions are better monitored and controlled. Were I still building T4 engines, I would probably switch to the product he uses. You have to pay attention when selecting the seals you use The inner seals are all the same, early outer seals are somewhat smaller than late version. I've encountered this issue often. They're usually 2 different colors, but not always, and both come in the kit. I've NEVER seen the correct outer seals shrink enough to allow the tubes to be loose, and I don't recall ever seeing the inner ends leak, even on engines I didn't build.

Install them dry or just engine oil and they will leak has been my experience.

I use the tiniest bit of copper silicone on the outside of the seals, and only use the viton ones. My engine is dry.

We pretty much only used the PTFE Loctite 565 before Viton seals were available. With Viton good lubrication is all thats necessary.

The Type 4 Rebuild Video was produced 15 years ago, lots has changed and honestly I feel that the video should no longer be sold, because its so far out of date.

Sorry, I just cant pass this one up.

I try to give a "+1" to Jakes product and get a "-1" from jake.

So Jake, are you trying to say that your engine sealant product is no good, or that your type-IV engine assembly video is flawed and we should stop using it?

Confused..... I have tried so hard to mend fences in the past 2 years but I just give up....

[Jake Raby]

Saying the PTFE sealant works great with standard seals in standard gasket sets. Also stating that its not necessary with the upgraded Viton seals.

And yes, the video is way out of date, it pre-dated the Viton seals even being available. It won't hurt if you use the PTFE with Viton seals, you just don't have to have it.

We have no problems between us.. Water under the bridge.

And in two weeks the Type 4 Store will no longer be a Raby company, I sold all the inventory, web site and etc to LN Engineering. Back behind the green curtain for me and Charles has a great plan for the store at his new facility. This allows me to focus on development and building engines only.

The good news is LN will bring back engine kits, something I lost all patience with a few years ago. Nine more days and we are done with retail sales forever! I can't wait! :-)

I have agreed to consult for LN and continue to develop products for the store, and to allow our developments that are spin-offs from the Aircooled Technology Turnkey engine shop to trickle down to the Type 4 Store for retail sales from year to year.
The only thing changing is where the parts are held and who's running the company, the site and components will stay the same and all Aircooled Technology engines will still be created exclusively from Type 4 Store components.

Formal announcement coming just after the first of the year. I am happy as HELL! You guys should be too, Charles is a hell of a lot better to buy from than I am.

That seems like a win win for everyone.

Kits, good
Valve train stuff....good

Now go build some motors.

Yep. With the Type 4 Store inventory moved to LN it frees up an extra 1500 square feet to add another clean room for engine building stations :-)
