Re: vibration, and oil leak

["Tom Nestor" <tnestor@cyberportal.net>]

Chris -
    Keep in mind that when the front/rear main seals weep the oil tends to
follow the pan/block mating seam and looks like a pan gasket leak.It could
also be the front/rear seal carrier to block gasket. Timing belt replacement
is naturally a good time to do the front seal, clutch replacement for the
rear. I believe if you remove the rear sub frame bolts and loosen the front
ones you'll have access to all the pan bolts. As far as the low freq
vibration, could be an inner cv or the diff bearings. In either case it
would be more pronounced at more extreme steering angles and/or under accel.
