Help! Changing timing belt creates oil leak?

[Denise Riley <parsely!sopwth.UUCP!denise@[199.2.210.148]>]

My recently acquired '86 4kcsq was overdue for a new timing belt
so we installed a new timing belt, water pump, and idler pulley.

The engine (5 cyl, non-turbo) runs fine, but there is now
a significant oil leak.  The brackets for the AC compressor
and alternator and the front of the oil pan are swimming in oil.
Removing the upper timing belt guard reveals oil splattered around
and a wet timing belt.  The upper part has a light splattering of
oil, it appears that there is a fair bit of oil around the lower part.
All this from a very short test drive.

While it appears there may have been an existing (minor?) oil leak,
(the usual oil+dirt gunk) the old timing belt was dry.

Possibilities include:

	crankshaft seal
	camshaft seal
	valve cover gasket
	head gasket

I can't see any oil dripping from the bottom of the camshaft seal,
although there is a bit on one side (seems odd).  Head gasket seems
unlikely.  Main suspect is the crankshaft seal.

We searched through the archives on the web, but couldn't find anything.

Questions:

	Are there any possible sources of leaks I have overlooked?

	Will oil harm the timing belt?

	Does the crankshaft seal seem the most likely?

	Are there alternatives to the special tools for
	extracting and installing the crankshaft seal?

	How would changing the timing belt and friends
	create or worsen an oil leak?

	Is there any place in the US-OR-Portland area to get
	this stuff on a Sunday?

thanks,
