Rear Engine Oil Leak

[frodo1028]

My 92 LS 400 has 146,000 miles and has developed a leak in the rear engine seal. I have all the service records for the car and the same seal was replaced under warranty at 52,000 miles. My questions are:

1) Is this a recurring problem for this engine?

2) Does changing this seal require removel of the transmission? :cries:

1. no

2. i think so. on some engines, you can get to them through the oil pan by removing the oil pump and it only takes a few hours, on other brands, they are on the outside fo the block between the engine and tranny.

Yes, you have to remove the transmission to get to the main rear seal. I did that some months ago with the help of an experienced friend of mine. No leaking anymore.

Good news: I took pictures and wrote a tutorial for lexls' great page. He said he'd put it together soon :)

Bad news: It's a helluva job. It took me 20 h of sweat and pain, but I saved around 1000-1500 bucks... A shop will charge you 7 hours, the seal is around $20. :cries:

Thanks Andy! I grew up working on cars and trucks in my father's shop (many moons ago) and am aware of what a pain it can be to remove a transmission. Especially if you are working in your garage without the correct jacks. A shop with lifts and the correct jacks has a huge advantage! I don't know if I feel up to the task. I will have to call the local shops and get quotes.
