im going to replace the clutch in our civic really soon, the thing im nervous about is the rear main seal. I did some searching and found that it has to be a certain distance from the back of blah blah blah. I dont want to have to drop my pan to just replace the seal. So my question is if i just finagle the old one out and slowly push the new one in and get it alittle past the lip of the crank and eye ball it so it looks even all around, will it leak? I dont want to install it, pull out of my driveway and have oil puke onto the brand new clutch and be back at square one.

Look real closely at the old one. Then if a new one is to be installed, eyeball it in.

 

thats what i was figuring but i dont want to do that and have it fail and do the job all over again u know what im saying, so if anyone can chime in that has done this it would help.

 

Okay, I will chime in, since I have done more of these than I can count.

First off, I look at the seal, really close. If its not leaking, and looks good, I leave it there.

If it is to be replaced, when inserting the new one, you make sure it is in the same amount all the way around. Pretty damn easy. The exact measurments ont he seal is roughly 0.5 - 0.8 mm

 

aight thanks for the reply man, im not as nervous anymore

 

i always replace these when doing a clutch job unless i know its been done recently in the past just for peace of mind... i also run a bead of silicone around the seal to help keep it from leaking or backing out

 

using silicone is it recommended?

 

i thought your just supposed to use a sealant or grease

nope

 

ive done this on every car ive ever installed a rear main seal on... i also use it on the front main, cam seal, etc... never had any leaking issues... to each his own i guess... everyone does things their own way... i did read an article in honda tuning where erick aguilar was building a gsr and he did the same thing... but what does he know anyway
