Can't comment on all the H20 questions since I'm an air-head, but I can
comment on the pushrod thing.
I'd find out *exactly* how this one got bent before I did anything else.
In seventeen years of VW experience, I've only seen a few bent pushrods;
not a common failure IMHO.

hello again collective wisdom
so I got my stuck cylinders free. thanks to everyone who responded.
heres
what worked. I tryed twisting and then prying the cylinder to no avail.
I
then thought what the heck--grabbed a 12mm open end wrench and used it
as a
fulcrum lever. man--with just a slight tug on the end--the cylinder
moved.
workwed my way around and out they popped--both of the stuck ones. So
the
people who recommended this--you are the winners.
onto my questions i'm seeking advise for.
1) my heads actually look amazingly well. havent scraped the glue off
yet--but they look to have no pitting. my guess is they were leaking
like
crazy when the gaskets hardened since it sat for 4 years after PO had
coolant pressurization issues (assuming inner O-ring here). there is a
crack
between valves on all 4 though. I was planning on taking them to
painters
grinding in denver for a a fly cut and pressure test. does this sound
like a
good idea? or should i clean them up and reuse them? or should i throw
them
away since there are cracks between valves?
2) since my cylinders became unseated--am i looking at potential trouble
with the lower o-ring? how hard is it to replace and how many people do
it?
seems like if i bring the piston to the bottom of its travel and then
let
the barrel ride with it out to the top of its travel (with care on the
other
3 of course) i can get at the lower one some what. Is this advisable?
3) since I have one bent pushrod--and I know all pushrods are to be
instaled
in the same place and oreintation. what to do. Buy one new one? buy a
complete set? or find a used one? I bet these rods are the same rods
used
forever and I probably have a ton of air cooled 1600 rods laying around.
Whats the thoughts there?
4) what other common items do people replace at this point? I am going
to
replace some hoses for sure that look bad. fuel line sure seems pliable.
I
have plans of eventually doing a conversion. so I'm not hip on replacing
everything. but I want to avoid break downs in the meantime.
any advise is apperciated--thanks in advance
mike
