Do I really have to pull the cylinder head to replace a damaged push rod tube?

No, that is the benefit of this collapsible tube. It allows you to remove and replace a damaged tube without pulling the cylinder head, saving you the better part of a day of work.

Are these collapsible tubes a reliable fix for my Vanagon?

Yes, this is a Porsche design used on all 930 Turbo engines in the 1970s and 80s. It features an aluminum outer sleeve, a stainless inner sleeve, and a spring-loaded design with a sealing o-ring.

Will these tubes leak oil over time?

Because they are a two-piece design rather than a one-piece design like the original, they can be expected to weep oil over time. If you have several bad tubes, pulling the head to install original-style one-piece tubes may be a more leak-prone and cheaper long-term option.

Which Vanagon models are compatible with this part?

This part fits 1983-91 Vanagon Waterboxer models, including 2WD and 4WD versions across various models such as the Westfalia Camper, Multivan, and Carat/Hard Top Weekender.

Collapsible push rod tubes are lifesavers when you've damaged one of your original push rod tubes. They allow you to remove the damaged tube, and replace it without pulling the cylinder head which would take you the better part of a day. They are a spring-loaded, two-piece design that seals with an o-ring in the middle.

They are very simple to install, but they can be expected to "weep" oil over time, being they are not a one-piece design like the original. If you have several bad push rod tubes, you might be better off pulling the head and replacing them with original-style one-piece tubes. They are far less leak-prone and much cheaper.

Aren't collapsible push rod tubes a hokey fix? Not at all! In fact, they are a Porsche design that was used on all 930 Turbo engines in the 1970's and 80's. It was good enough for them, so it is good enough for us!
