Rear Main Seal

[Niko97RS]

How hard would it be to change the rear main seal on a 93 camaro? Anyone ever done it/ have any advice?

Re: Rear Main Seal

Re: Rear Main Seal

you will have to remove your flywheel. It can be done but is a pain if doing it in a driveway. If you have a lift it is easier.

Mine has dripped a bit since the day I got it when it had 77k on it. Now over 105k and never changed it

Re: Rear Main Seal

I've wondered the same thing...I know its like 600$ to get a shop to do it...would mods help to make something like this worse?

I just thought that if you did something like a cam it may help to make the leak bigger...I dont know about the original OP but mine leaks when I hit 3k rpm or above...goes right onto the y pipe and stinks like crap so its annoying...is there a walk through guide to do this yourself?

Re: Rear Main Seal

the only reason i did mine was because i was replacing my clutch. the oil pan is my pita lol

you would have to drop your transmission, if your a manual you would have to remove your clutch and flywheel. then becareful getting the old one out. not to strach the plate.

Re: Rear Main Seal

ok thanx guys. btw its an auto.

what about lucas transmission treatment, it says it would stop most leaks....anyone have any experience with that?

o and one last thing..."technically" if i just slowly keep adding tranny fluid, that just like a small oil leak, it wont affect performance right? as in my tranny isnt going to seize or break right?

Re: Rear Main Seal

i think they leak oil not tranny fluid

Re: Rear Main Seal

Not sure how different a 93 is,.,.I have a manual 99 and while I was at it, I've changed the clutch since I was dropping the transmission. IIRC, I jacked up the car(of course) then I pulled out the driveshaft, drop the tranny on the floor jack. Changed the clutch, took the old seal out. When I took out the seal, all the coolant came out along with oil. The hardest part is scraping the remaining seal off. Cost about ~300 bucks for all the clutch parts and seal. Seal was way cheap as I recall, I think ~$5. There was a line going into my transmission that requires a special tool to disconnect.

Good luck =)

Re: Rear Main Seal

well if your doing a good clean you don't want to scrab it up. then you won't get a good seal.

and yes you would leak oil not tranny fluid. rear main seal is on the back of the block.

Re: Rear Main Seal

mine does a drop every once in a while. when i first got the car. i had somone tell me it was the oil pan gasket we changed it out and i still saw a leak every once in a while so the guy was wrong.

Re: Rear Main Seal

Make sure your PVC valve is working before you change the rear main. The PVC can be clogged and cause pressure to build up in the crankcase, the easy way out is the rear main and it takes oil with it.

what?

you have an even bigger problem if your rear main seal is leaking transmission fluid.

but in any case, DO NOT use those lucas crap products, when used with "gears" they cause small bubbles which can ruin your oil pump/transmission/differential gears.

if you dont believe me, go find one of those little displays at the part store and spin it really fast compared to the other oil, you will see millions of bubbles in it
