Push rod tubes

[Dewie]

When placing the tubes with heads on what is the besy way to set them? I did not buy the expandable tube like I read about in a forum from CB but that looks like the way to go next time. In the mean time after seating a rod wrong I broke a lifter and need to replace the lifter and rod and tube. Got a suggestion. Any would be appreciated.

get a new lifter, rod and expandable tube from CB.

I don't think there is any way to use an OE pushrod tube with the head in place. They make the expandable pushrod tubes specifically for that purpose.

EX pushrod tube are a patch, they are meant to leak with time.

I have read more then one time on the forum about making a tool to put the push rod tubes in place with the heads on, even the Bentley manual says it is possible,they just shove the block side in and then expand the tube towards the head to prevent the oil from leaking around the block. I have not seen tubes leak very often on the head side, it is usually on the block. I found the expandable tubes in CB but would like to know which ones you use on a 1.9 lt. The next time I mess with my block I will use the expandable ones, for 90 bucks a set I agree that is a good idea. In the mean time, has anybody replaced a push rod tube with the heads in place and had success?

I think you are mistaken about what the Bentley says. I am sure it is refering to expandable push-rod tubes.

You know Gordy after reading the black part of the writting .It does state, pushrod tubes supplied as replacement parts can be installed with engine in place. I am ordering the CB ones in black and silver. Thanks Tencent for the direction.............

I purchased a set of the Jaycee brand (Rebel Red) pushrod tubes.

If you find yourself in need of a few, PM me.

Wheni replaced eng in mine last summer i used the oversize 3-oring expandable ones,doing fine so far and picked up at a show for the price of 2 stock ones. Last time i replaced one side with new 2 of them leaked where the bellows were and i decided no more stock junk-China ??

Could someone please clear up a few things about what's available and what will fit a Vanagon in terms of pushrod tubes? Here is what I'm confused about:

I'm in the market for a set of expandable pushrod tubes. I do know that on the Vanagon, the head side side and block side are different diameters.

I know that there are pushrod tubes sold specifically for the Vanagon which meet these dimensions. Am I understanding correctly that the standard ones for the Beetle are the same size on both ends, and that if you are looking for ones market for a type 1 engine, you need ones specifically for Beetles with ratio rockers to use on a Vanagon, so that the tube are of a wider diameter on one end? And that you use them flipped around on a Vanagon, right? So a normal Beetle has the pushrod tube the same, smaller diameter on both ends?

Which brings me to my second question- I'm thinking of the Jaycee ones at CB performance. They tell me that these won't fit a Vanagon, but I believe they are the ones referenced in several posts here which people have used. But what about the seals. Am I thinking correctly that if the tubes are for the ratio rocker type 1 engines, and come with seals, that they are appropriate for the Vanagon? CB lists different seals with a type 1 1.7 engine than the 1.6, for use with the same pushrod tubes. I know I need two different diameter seals.

I'm sourcing these parts, and my mechanic is installing. He was going to use one of the other brands of expandable tubes, but it seems that people are having good luck with the JayCee ones.

Thanks for any advice.

Without rufflin' feathers.....just trying to help.

IMHO,

Benny is correct when talking about the VW tubes that were designed to allow for a lifter to be replaced with the understanding that a proper rebuild is in the future.
I agree they will leak if used for the long haul.

Tencent is correct about the aftermarket versions available.
I have a 2.2 Boston Bob with rockers and worked heads using the aftermarket sealed three piece expandable tubes. The last I calculated I am almost at 100,000 miles on this rebuild and not a drip of any fluid anywhere. The time was taken to seal up everything just as Benny has shown on his site. The last 20k miles have pretty much been a torture test, towing, offroad beating and reving to the limit. I thought this engine would have expired a long time ago....nope and still dry as a bone and pushin' hard.
The waterboxer, when built properly is OK in my book.
The two Gents I am referring to in this reply know a little about this engine! (understated for humor)

[Tooharsh]

My 1.9 has 69,000 miles on it, slight oil leak at the push rod tubes.

Is this something I should fix using the expandable tubes?

Also, it was mentioned that they will eventually leak and a rebuild is in the near future. Would that be true on a vanagon with 69,000 miles?

Look forward to your thoughts.
