I use These They work Great and work much better then the more expensive Styles intended for use on Vanagon's sold by the popular Van Shops.

These are also very Sturdy plus they don't leak oil in time as the Vanagon modes do. They are made so the downhill drain oil returning from the Heads to the Block flow's into the smaller tube 1st then the larger ones because the smaller Tube sets deep enough so basically oil doesn't have to be stopped by the O-rings as is the case with the Vanagon versions. Because of this design the O-Ring seals won't leak as easily as the flimsy Vanagon Styles do. The Vanagon style replacement Pushrod tubes would look reverse of what these look with the larger tube upwards towards the heads and flowing into the smaller tube. Thus the return oil must depend on the O-Rings to hold back any leaking / dripping Oil. When 1st installed the Vanagon versions do there job but I have seen almost a 100% oil drip failure over time plus they are flimsy and very similar in gauge as the original pushrod tubes so there bend easily. But these are more of a thicker pipe design where the smaller Pipe slides into the larger pipe and sealed by O-rings

Lastly this version have much more spring tension to push and seal against the Heads, and Block helping to eliminate oil leaks in those areas.

Once I discovered these gems, I stopped using the very expensive Vanagon ones on customers Vans. And so far all Happy Customers.

Ohoooo plus you can get like a set of 8 for what you'd pay for 2 of the Vanagon styles. But this style is only sold in a set of 8 replacement pushrod tubes. Usually around $80'ish bucks.

Lastly these were designed for the Type1 VW Bug Engines. But works wonderfully on Vanagons.

Has anybody tried the scat "Big Mouth" version of these?
I'm looking to try them on a 2.1 WBX.
Seems like the same thing described here.

Mine are on the way as well, but will arrive while I am out at a reunion in CA. It'll be the 10th or later before I get to even look at them. Will post back when I've got pic's

Got one side done tonight, I am not sure about the nature of the 2.1 WBX end of tubes sizes vs the 1600 these may be for, but I did follow the instructions and put the spring end toward the block. It was just not possible to grasp the relatively small surface area of the end of the tube to do it in an opposed manner. In this case, I installed them as instructions say, but not as is obvious the size of the end seals of the WBX seem to suggest, the smaller end seems to want to be at the head, and the larger at the block.

I will have to see if they leak, and reassess after trial. The way these are now installed, there will be pooling of oil in the tube, instead of the oil flowing back without the 'step' blocking the flow slightly.

It seems to me that I will have to remove these and swap end to end, however, I have no idea how to grasp the tube with enough force to get them to compress them if in the opposite direction.

Decided I don't even want to try running the engine with the spring toward the case. I am going to take the rockers and rods back out tonight, and turn these around. I've done some reading on how to grasp these things, by adding a hose clamp. I might see how 3 or 4 zip ties would work too. Was just too intimidated last PM by my inability to grip the small end. I realize they really do need to be spring end out, contrary to the instructions which seem to be for the 1600 AC engine.

Plus.. I lost my feeler gauge so I expect a new one tomorrow. I'll check to see what is up with my valve clearance while I am at it.

It looks like I have a bad lifter and searching for this style push rod tube I found these at fastfab. They are designed just for the Vanagon, the description says they are new. Has anyone got info on these?

Got them turned around. Amazed at how difficult it was to grasp them, and force them to compress. Was a serious struggle, and came to four letter utterances. A couple zip ties made it possible to get the grip I needed.

Unfortunately, on closer inspection of all parts involved, I see the faces of the rockers are scarred, and one push rod is slightly bent. And even worse, the wire circlip on the #1 exhaust lifter is malformed/bent, barely hanging on, to keep the lifter together. I tried using a pick to pull the lifter out, but it got hung on something unseen about half way out. Not sure of next steps, but its a three ring circus, for sure. I believe that if I can get the lash to zero plus 1.5 to 2 turns in, the pressure on the circlip will be negligible. It is just barely possible that the clip can hold it enough to keep the whole lifter from blowing chunks.

Regarding the collapsible tubes tho, it helped to use a few squirts of oil on the inner bore of the outer shell and on the o-rings. Worked the spring and slide function a lot before attempting to install them backwards to instructions. Seems a good fit now tho, I am hopeful, at least on the portion involving the tubes themselves.

About 6000 miles on these now, so to revisit this:

I've got some slight seepage from the case on one, and head on two. I saw another post that I can't find just now showing some slathering of a gasket-maker type material on the ends. Anyone know what that product was, or have a similar product suggestion? I got to pull these again and put some goop on the ends. Yes, it'll be yet another struggle, but that's just what we do, right?
