Default Replacing the main seal

Has anyone done this before and have any tricks\tips? Mine is seeping.

Step 1 - Get the service manuals, right? Definitely doing that before I get my hands dirty.

Anything to check and replace while I got the engine apart? Things to watch out for? Thanks guys.

I haven't done this before. I'll be working with a friend who said that on some cars it's easy and on others it's a real pain so I wanted to know what to expect.

I have a 93 GS300 with 49k miles. Just FYI, the dealer will do it for $830.

Default Amount

Seeping?

Is it leaking enough that you need to top off the oil level between changes? By how much?

You might want to just ignore it, you can buy a LOT of engine oil for $830.

I'm not going to pay $830. It's only going to get worse so I'm doing it myself since I have some time.

Default Personally..

I'd put a drip pan under it when it's in the garage and not bother with it unles/until it does get "worse". It may not get worse.

And by the way the only experience I have had with a Lexus rear engine seal failing (a teaspoon/night) was immediately, the next day, after the car, a 91 LS, went in for the 90k service. The dealer didn't think that anything they could have done would have resulted in the seal failing so suddenly, and basically I had to agree.

Cost me about $1000.

I later learned that if the LS is over-filled with engine oil and then run that way for even a short period then this is a very common result.

Default interesting...

Perhaps I should do a through undercar cleaning and see if the Lexus dealer finds this "problem" again. Thanks.
