I am going to be replacing my clutch as soon as I get a couple of warm days and was planning on a little preventative maintenance while I have the transmission out. I'm replacing the motor mounts and the shift linkage bushings with ES parts and was wondering if I should replace the rear main oil seal. It's not leaking now but I do have 151,000 miles on the clock. Should I bother? If I do should I use OEM or aftermarket?

 

If you're pulling your clutch already, go ahead and do it imo. Go OEM. It's only about like 10 bucks or so, iirc.

 

Anything else I should replace while I'm under there that I haven't thought of?

 

might as well do the front main seal and put new belts.

 

The belts are fairly new and I hadn't planned on pulling the front of the engine apart. I was talking about things I should do while the transmission is out. What are common replacement parts at the rear of the engine that would otherwise require pulling the transmission or would be easier to get to with it out?

 

Don't forget the lip seal as well...separate from the main.

 

OEM seals fosho. Likely it wont develop a leak anytime soon but if it is easy then go ahead and prevent a future headache I suppose but that can be said about a lot of stuff I guess. Mine is OEM and I dont expect it to leak for another 50k or so

 

Very good to know! Thank you!

 

I was looking at the price difference and it's only $2. So yeah, I'll be going OEM.

 

I would do the half moon seal on the upper oil pan and add a decent amount of silicon/rtv as that is where mine leaks and seems to be a problem area on most machines. You also have to pull the pans anyway to get to the RMS, but i am not 100% on that.

 

What is the part number for the oem rear main seal? I will be replacing my tranny soon and will need to replace the rear main seal also as it is leaking, but so far I've only found aftermarket ones.

Still haven't found this though...unless it's included with the rear main.

 

Same as half moon seal mentioned by another poster.
