1 pc. Rear Main Seal Question
 

very simple question. on a one peice RMS, which way does it go, does the flat side go towards the flywheel, or the rest of the engine?

the same way the old one was in :p

lol, anyway I think the flat side goes to the flywheel, since that is how I screwed in some screws to get the old one out

I dont remember, and i just checked the old crank and the damn seal was off...

you sure, id rather not **** this up

check the chilton manual, thats what I used

it doesnt say, but it LOOKS like the flatside goes to the flywheel...

on a side note, should i just put assembly lube on it instead of oil?


nevermind, it says install with "spring side" towards engine, is that the side with the groove?

the flat side faces the flywheel, Its only goes in one way tho....

the side which you can see the spring is the spring side

ah, so yeah, okay, gotchya


but yeah, oil or assembly lube?

use oil

Flat side out, a little oil on the inside lip of the seal. I like to just a light coat of RTV on the outside of the seal where it meets the block. Ive seen these seals leak arounf the outside. I put the RTV real thin and then drive it in. Make sure you work the seal up easy so the lip doesnt flip and tear. If the crank has a small grove where the old seal was you can buy a sleeve to repair it.

+1 on the rtv around the seal. i've learned the hard way, mine still leaks and i didn't use RTV :(

and i didn't know there was a special tool to put it in

I didnt need it, and I didnt use rtv and mine didnt leak :D

Of course Ford has the tool. As easy as it is to put the seal in it's a waste of money. If you do a bunch of them you can go to Wal-Mart and buy a hard plastic Glass thats the same size as the seal for 1.59 and use it and a plastic hammer to drive it in.

Most of them won't. I have had a few of them that had already been replaced by the owner. They had the bright Idea of driving a screwdiver under the seal and put a nice dig in the outer seal surface. I didn't see it and it leaked. After that they all get a coat of RTV. Very thin but no leaks since

yea I agree, I will use RTV on my next swap, I got lucky that mune had a nice smooth seal surface

I dident use rtv and mine don't leak, just make sure it goes in perfectly....use the old seal to hammer it in.

instead of making a new post, i figured id ask it in here since its some what related. As i previously stated i still have a leak from back there. i read/heard that you are suppose to put some rtv on the rear main caps where it meets the block., is this true? cuz i am curious. thanks

read all the posts ;)

i re read and it says nothing about main caps
