1968 Beetle with an 1835cc engine...
If anyone can tell me what the procedure for replacing the Crank pulley
seal, it would be very much appreciated....I was wondering if it can be
done without removing the engine.....Pls send reply to VWBUGme1@AOL...
Thanks for the help!!!
67 resto in Progress and 68 Beetles
While I'm asking for info....Has anyone ever done a Pan off
restoration....Is it as easy as everyone says....Ha Ha Ha....

There is no seal on the crank pulley! If oil is leaking here, you either
have inadequate crankcase ventillation or a worn pulley. If you rev the
motor high (4500+RPM) and have only stock crankcase ventillation, oil
_will_ come out from behind the pulley. BTW, you may want to check to
see if the oil slinger is installed correctly.

I have bad news for you. You don't have a crank pulley seal! The only
exception is if a "sand seal" has been installed.
Oil coming from this region is due to excessive blow-by, clogged
crankcase vents, or a missing oil slinger on the crankshaft. It might
also be that a pulley that was machined for the sand seal was
inadvertantly installed in a non-sand-seal motor. Too much oil or
parking uphill can do this too.
The pulley can be removed without pulling the engine. Just take off the
rear engine tin and you'll have plenty of room. You may need to
make/buy a puller to get it off.
Make sure that the front projection from the pulley (that extends into
the engine) has the spiral groove and that that groove is clean. The oil
slinger is a washer that can be seen through the crank hole when the
pulley is off. I don't think that it can be removed with the pulley out,
though! You have to split the case for that (ugh!)

Well, like the last poster stated, you did not have a
seal here ORIGINALLY, but you don't have an original engine
anyways since it is an 1835.
Assuming you don't have one (most likely), you have one
of the normal problems for a street engine with 92mm pistons,
excessive blow-by.
There is nothing you can do to SOLVE the problem other than
change the pistons and cylinders (preferably to 90.5s) but you
can pull the pulley and make sure the "threads" on the pulley
that throw the oil back into the engine are not worn off, or
clogged with shit.
A second "band-aid" would be to add a breather box to you
engine. For that matter, make sure your crankcase breather tube
is clear, and is vented to the carb(s) air cleaners. If it is
just plugged up, that will cause the same thing..
Good luck,
John

I don't know too much about this kind of problem, but as fas as I am
aware, there is no seal at the pulley end of the crank, just a
centrifuge that forces the oil back into the crank case. Please
correct me if I am wrong. It is very rare for oil to leak from here
and I think it will involve splitting the case to repair it. Sorry!

There IS a seal in the crank pulley! Is it the front or rear side of the
crank? if it's the front, split the case to change the seal. Pull out
the engine, as much as you don't want to do it.
see the Muir book for more info.
