Rear main seal leak
The top is removed by using a small punch to push the seal through and around. Once you punch it through the opposite end will protrude and you should be able to use pliers to pull it out. Oil up the new seal before installing it. Be careful not to cut the seal on the sharp edges when you install it. Use some sealant in the corners when installing the bearing cap.
It was running rough because I don't think the spark plugs had ever been changed in its 159K miles of life. The band's in the transmission were really loose, the rear one adjusted fine, but the front one looks like a piece was bent so I'm waiting for parts (and while I'm in there I'll just replace the solenoids and sensors for good measure). If that doesn't work then I guess it's either a full rebuild or a new transmission... Depends on how I feel and how empty my wallet is I guess.
After that, it's just the oil leak which is dripping off the front of the bell housing which makes me think it's the main seal.
If it all goes well I'll be into it less than $3500.
No idea why I'm sharing all this in a forum I just joined for a vehicle I haven't owned more than a week. I guess I'm just excited to finally own a 4x4 truck. Even if she is old and in need of work, I like working on things like this.
Check up on top of the motor for oil leaks as well. Oil pressure sensors, distributor seals, and the seal on the china wall at the back of the intake are also good places for leaks. The oil runs down the motor, and makes you THINK the rear main is bad, when in reality, it's not.
