Subject:      Re: Replacing pushrod tubes
Content-Type: text/plain; charset=us-ascii

Oh *&@#...I just ordered the non-collapsable pushrod tubes on purpose, but I don't want to remove the head. I'll spare you the newbie reasoning that led to the purchasing decision. I'm going to return them and order the collapsable kind--can I assume the seals are interchangeable, so I won't need to exchange them, too? (BTW--I did order different size of seals for the different size ends of the tubes.)

Below, I've copied some important-sounding pushrod-tube-seal-replacement info from the archives. Enjoy!

It never occured to me that I could replace JUST the seals (duh), but it seems to me now that having the collapsable type will save me a lot of work if I need to do this next time.

It's good to know I can probably skip the readjustment of the adjustment screws on the rocker arms...Thanks, Brad & Pete.

>>steve, check and see if your tubes are bent. every time i've done mine, at least one or two get 'bent' a little, so i get a bunch of brand new ones. i also put a little axle grease on each seal (just a wipe) so that it slides into position easily. and clean, clean, clean the places where the tubes and seals fit into on the head and on the case. don't leave any old seal or crud on either head or case ... it'll start leaking again.

another possibility: if you happened to have gotten crappy seals (say, from an less-than-reputable FLAPS), you might wish to try another source. you could also try a trick my brother told me about: on the type 4 engines, (1972-1983), they used the porsche seals for the 914/912E ... it seems that the porsche seals lasted longer than the vw seals and could withstand the heat of hard running better (in their opinion). but the porsche seals cost more.

off hand, i'd bet your leaks are caused by some old seal/crud left in the head/case 'socket'. that happened to me a couple of times, and finally i figured out that whenever i did the seals, i needed to really really clean (like with a rag soaked in grease-remover) the tube sockets.<<
