Need to tap into the brain trust.
I was just looking at a YouTube video on a type 4 engine assembly. I noticed that person attached a wire to the valve assembly. I looked at the F/S section and noticed that there's set for sale. Question, is that a monitory to install guide the push rods?
Thanks for the education.

It's a retaining feature for the pushrod tubes. It holds them in place and keeps them from wiggling loose and causing oil leaks.

They are a must. The tube will back out and make an oil slick of your trans, rear of the car, and the windshield. Yes, windshield. The one on the car behind you.

Thanks for the reply, I also called AA ...since I bought there cylinder with JEs for their comments. They mentioned as above, but in the 25 years of buildings type 4, they have never seen any back out. I mentioned that push rod tubes with new seals were a very tight during the install.
Any other comments?
Thanks in advance.

I have seen them back out! If you think about the fact that it is just an interference fit you know that with all of the heat cycles an engine goes through it is just a matter of time before they become loose and leak at a minimum.

The engineers that designed the Type 4 put them there for a reason and I am sure they were smarter than most of us!

They will back out.
I have seen set screws run up from underneath on large motors with custom rocker assemblies, but in the end, you need some way to keep them in place.

They're talking out their *ss. If they'd been building without the retaining wires for 25 years, they'd have seen a whole bunch of them back out. Or maybe the tubes have backed out, but they've told people to pound sand if anyone had the temerity to complain? That wouldn't be out of character for them...

You need a little more in there, Elliott. I only see a few places where there are blobs that can break off and wind up plugging up one of your oil passages--you want lots of those blobs so you can be absolutely sure to lunch the engine!

To all, thanks for the education. Looks like its best to install them while the engine is on the engine stand.

Tight confines with that barbed fitting and the intake manifold.
