Leak between Transmission and engine

I let my 1988 Toyota 2wd pickup (with 22R engine and 4 speed manual transmission) sit without running for about 3 weeks and now after I turn it on, it leaks from where the transmission connects into the engine. What gasket might have broke and is there any sealant I can use so I dont have to take it apart?

Leaks what type of fluid......

Manual trans fluid..(Gear oil) coolant or motor oil?????

look carefully at the top of the engine near the back......Fluid doesnt leak "UP" , so a leak in this area may be confused with Bellhouse leakage.

Your rear main engine seal is damaged. It requires the dropping of the transmission to fix. Any type of "sealant" you apply would just be temporary if it would even hold.

And you have the 22RE motor, not the 22R, correct? I had a '88 4x4, and it was a 22RE. Doesn't make a difference here, just wondering.

It looks like its oil and I have a 22R with 2 bbl carb. What sealant can I use for temporary fix? Do I just put it in the crankcase?

Dropping the Transmission and putting in new rear main seal is alot of work?

If you are sure the leak is comming from between the motor and trans..You will have to pull the motor out. Put a new rear seal in the motor and a front seal in the trans. No type of sealer is going to help.

There are oil additives that claim to soften age-hardened rubber seals, but I doubt they would have any effect on a 20 year old rear main seal with (I'm guessing) 200,000+ miles on it.

While you're in the neighborhood, clutch parts and pilot bearing.
