if its the rear seal where the driveshaft enters the trans you need a transmission output seal for the tailshaft housing.

SOURCE: 4-3 vortec gas in my oil 1994 s10 blazer . vehicle was running

it doesnt take long to ruin the engine diluting the oil with gas - i dont know how i dodged that bullet, mine was leaking -gas into the oil- new spider is only the beginning of the care and feeding of the unpowered poppit spider motor- regular bottles of injector cleaner will keep them poppits clean, otherwise fuel deposits mess up the quantity and pattern of the fuel spray quickly from new- i had long suspected the new spider i installed was faulty, (Sorensen), but it was just quickly plugged by fuel deposits-as i understand it, the additives often in gas like to hook up in the poppits- my 1994 4.3 S10 kicks **** now, runs like it did when i bought it 5 yrs. ago, smooth like its supposed to, i was chasing the piggy/miss for two yrs, bottles of injector cleaner didnt help, it needed a heavier mix of cleaner
- it couldnt hardly get itself and a little aluminum boat out of a easy boat ramp, what broke free the deposits was doubling up on the amount of injector cleaner i dumped in the tank, when a person takes a clogged injected vehicle to a shop they hook up a pressurized system to it ,and disable the fuel pump -shop air system is better than aerosol can system, force the engine to run on a <10%> cleaner/gas mix for 20 minutes, guess i did get lucky with results from the cleaner addtive, cuz the real fix is find a shop that does the 10% cleaner 15-20 minute pressure wash of the injectors, and it should be done at least every year- mines running so good now, ill not see a lot of results from the pro cleaning i'm scheduled for tomorrow morning - hate to cancel tho- these unpowered poppits are very finicky - i did reuse my plemun half shell gasket, it has the red rubber line on it and it was still live so i reused it

4-3 vortec gas in my oil 1994 s10 blazer . vehicle was running

95% chance its the fuel injector (spider). Take the upper intake manifold off and turn the key on and off a few times and you will see fuel leaking from the spider.
