grease and oil in the bell housing

[DUECE-COUPE]

pulled the starer and a bunch of grease and oil cam out and has filled the bell housing. What causes it and how hard is it to fix? will it affect the operation of the truck?? should i bother fixing it or leave it alone.

Is the drain plug inthe bell houseing??

You could have just a very small leak and with the plug in it just built up over time. The plug should remain out unless you are going through deep water.

It can affect the operation of the truck if any of the grease and oil gets on the clutch. I'd try to clean it out the best I could without pulling the trans.

I'd clean it out, leave the plug out, check all my fluid levels, and run it for awhile to see if you've got a leak. If you overfill the trans it will leak into the bellhousing. It could be that somebody overfilled the trans in the past and the oil didn't have anywhere to go because the plug was in place.

make sure the tranny is not coming loose from the bellhousing. i developed a leak on mine and in researching it(crawling underneath) i discovered the tranny was a bit loose. the 5 bolts that hold it to the bellhousing had worked loose somehow. the 5 bolts install thru the bellhousing into the tranny. they penetrate the transmission meaning when you take one out the gearoil will pour out. this might be your issue. gearoil could be seeping around one or all of the bolts. not a real big deal to fix.

Is it possible for engin oil to get into the flywheel housing?

I have what looks like motor oil coming out of the drain of the fly wheel housing.

If it is possible what could be the possible causes to this?

Is it possible for engin oil to get into the flywheel housing?

Yes. If your rear main seal is leaking, you will get engine oil into the bell housing.

Yes. If your rear main seal is leaking, you will get engine oil into the bell housing.

Can the rear main seal be replaced without taking the entire engine out?

Can the rear main seal be replaced without taking the entire engine out?

Yes. There are several threads here on the process, here is one:

Again, there are several, I just linked that one because the first post has pictures of the seal.

I also heard running at high speeds can cause that same issue (oil in the bellhousing).

I clean mine periodically with brake cleaner.
