I hear from some shady tree vw mechanics
but not first hand that the empi 4109
http://www.empius.com/catalog/empi2005_pg27.html
$64us for 8
OR
SCAT 20175
https://www2.cip1.com/ProductDetails.asp?ProductCode=C15%2D20175

work as direct replacement for the vw 025-109-337
($119/push rod from dealer and still $30 OEM)

Can any one confirm this or tell me they have used em on a 1.9L or 2.1L??

well turns out that cb make a reversible tube that has 1 end bigger than the other & they have tried em in the vanagon and they work just fine

Are you referring to the emergency adjustable push rod tube used when yoiu do not want to take a head off? For example when you replace a bad lifter?

YUP, not sure about emergency I understand these spring loaded tube are normally reliable durable
Its just the beetle tubes are much more cost effective & the empi 4109 are supposed to have a slight larger top end so that they work quite well in the vanagon

They will not work on a vanagon motor.. On a bug, both ends are the same size... On a vanagon, the inner end is larger so you can remove the lifter without separating the case... As far as I know, nobody makes a spring loaded tube to fit the vanagon...

will just so you know they exist but are $$$ 30-50 /tube
vw 025-109-337
http://www.bus-boys.com/parts1.9.html
http://busdepot.com/details.jsp?partnumber=025109337
etc

but my question was specific to the empi 4109
I keep hearing from a friend or friend who has used them in vanagon
the word was that the 4109 have some type of flared end
so its a tight fit in a beetle but will work in the vanagaon.

So this post was looking to confirm first hand that someone here and tried it with success

Have no idea what brand I used, nor do I remember how much it cost, but I replaced a leaky tube 40,000 miles or so ago and have not had any problems since. Bought it at my local VW flap.

Is the colapsable tube and is the emergency repair tube used when you replace a lifter. It is special and a bit complicated and that is why it costs so much. BUT, it makes changing a single lifter much, much simplier because you do not need to pull the head.

I was going to make a Post asking about the Spring Loaded Push Rod Tubes when I did a search and noticed this topic..

Has anyone used the Spring Loaded Push Rod Tubes, and if so do you remember which one you used and any Pics?

I have a leaky Push Rod Tube that I need to replace. No other problems just a leaky push rod Tube leaking at one of the base Rib Flex Bends. Thinking maybe it's cracked, but reguardless it needs to be replaced as I'm lossing to much oil.

What brand would you guys recomend, anyone try the BusDepot version?

I got mine from CB performance per suggestion from tencentlife. It is made for a bug engine but you install it reversed. i.e. large end to the block and small end to the head. Don't remember which one I bought though.

Must be same ones i used 3yrs ago on mine. Have double o-rings and the 'big end has a flat washer that goes on under the seal, keeps it positioned against block correctly, been doing fine. Mine have pretty strong springs and in my opinion will rob some of cyl head nut clamping tq as i had a compression (small) leak at 1st, re-torqued and added 5lbs tq, been ok ever since and a lot of miles.

After much frustration not finding an "easy fix" I found this on the Bentley site for those early vanagon owners who are not finding parts.

Additionally, you can find these parts and proper seals at Airheadparts.com

http://www.airheadparts.com/vintage-vw-parts/vanagon-camshaft-rushrod/pushrod-tube-021109335-c

Apparently there are no spring loaded options for the 1980-1982 models, but the new rod (or cleaned up old rod) is supposed to push right through the head and seat into the cylinder block without much effort, get new o-rings top and bottom!

Good notes cut from Web post: Admittedly, this can be a good thing to do if you want to replace pushrod tube seals anyway. Replacing these seals correctly can be an adventure in itself. In short: don't use RTV. O-rings work on clean, lubricated surfaces by compression. That tube of blue, orange, red, or black goo won't last-- you'll be back again facing the same leak in a few months, doubling your labor and aggravation. After removing the aforementioned parts, immaculately clean the areas surrounding each lifter bore. Ideally, you should do this the day prior when you pulled the under pushrod tins (if present). It's also a good idea to soak bottom of the engine block with degreaser in advance. Scrub the block around the tubes with a toothbrush, hose it off with hot water, then let it set to cool and dry overnight.

After that, clean out each bore carefully with kerosene and paper towels (as many as it takes). Clean the bigger part of the bore where the pushrod tube O-ring has been riding and you make sure nothing is up in the machined lifter bore itself. Pushing a scrap of towel back into the top of the lifter and using a toothbrush on the bore where the o-ring sits is good. The towel prevents debris from settling back in the bore.

Do the same to the bores over on the heads. Install Viton o-rings with silicone grease (or at least oil) and those tubes won't leak again. Verify the tubes are not dented where the o-ring sits--that will cause a leak. Also, if you are experiencing blowby (gases that slip past the piston rings, pressurizing the crankcase) nothing will stop the leaking.

Cheers
