As i have had this truck for 5 years, it has always leaked a littel.
my problem now is i have started driving 70 miles round trip to work and the more i drive the more it leaks!!!
how hard is it to replace the front seal???
keep in mind i am not a mechanic.
my trip is mostly on a long strip of highway where i often have to pass people who dont seem to be able to drive the speed limit.
and it seems to leak more and more!

Re: leaking front seal 1986 chevy s-10
Need to know which motor. Of the 2 base configuration available in that year, Both are not too hard to replace. Removing the front cranshaft pulley is about the hardest part of the job. Just be happy it is not the rear seal which is much harder and time consuming. Hope this is helpful. Good luck and have a good day.

never guess here.
oil leaks, no engine stated, nor year, so you wont get good advice.
mines a v6 2.5L
on most suz engines, front leaks can be.
1: top front of valve cover seal. leaks. then gravity does its thing.
2: top cap seal
3: bottom seal
4: pan seal,
5: pump seals.
doing all on a guess. is $$$$$$$$
what we do is clean it all , run for 10 miles, and see what really leaks.
use the UV dye kit. and find it.
you have gravity and air currents that form a chaos. there.
so only those 2 work.
The Borg Warner T-5 manual transmission has no filter. Assuming the leak is not really the rear main seal of the engine leaking, which is more likely, then it leaking from the front of the transmission. You will need to drop the transmission to get to the front seal on the first motion shaft. Unless you are really mechanically inclined or have a friend who is, leave it to a good shop.
Clean it with brake cleaner with the engine off, blow it dry, make sure the oil is full Drive it aabout 5-10 miles to get it hot and crawl under and see if there is ANY oil drops from the seal if so its leaking if Not maybe longer Drive or its not leaking .
