Zimbo,

Well, they all leak, but this looks a bit more than usual. Rear main seal is my best guess. Oil looks a bit black, may be time for a change. As for the threaded hole, I think it's supposed to be open unless fording rivers and such.

I agree with bugeye. That is the clutch housing drain. If oil
Leaks from there, it is usually the rear main seal. No plug should be put in there.

is this rear main a nightmare , do I have to take off driveshaft, tunnel covers etc I assume the gearbox needs to be dropped and clear of working area
any idea why it would leak all of a sudden like that , the only thing ive changed recently is the air filter bypassed the oil bath for a while

Is the crankcase being sufficiently vented? If the vent has been eliminated or obstructed, the pressure could build up, blowing stuff past the seals.

I don't have a 2.25 engine, but venting usually takes the form of a vented oil fill cap or a PCV system.

I checked the venting all seems good , I did a oil change also dropped the pan cleaned out the sludge ,new gasket installed new oil and filter , drove around town and leak seems to still be there , rear main job in the pipeline . any ideas on shop rates for this I will have a shop do this too big for me

I had a shop do mine last year. Small local garage, that I went to high school with the owner. I think it set me back around $900. I did pick up the parts, including a fresh clutch, I removed the wings radiator and breakfast so I could save myself some shop labor.

Yup rear main. First job I've ever had a shop do for me. I also had a new clutch plate installed. I wish I had the trany seals or transfer case done too they're now leaking like crazy too.

This isn't a terrible job to do yourself - it's just no fun. In a nutshell... take the seat box/floor/tunnel out, disconnect the rear prop, and you should be able to pull the transmission out. I think I had my tub off at the time, but I don't think that was necessary. After that, you can get to the rear seal by removing the drain pan. The seal (~ $15) is sort of an interesting split design. Replace the clutch before you bolt the transmission back on.

I can't say doing it made me a better person, but it really wasn't that bad.
