Average cost to replace rear main seal?
Hey guys, just wondering what I should expect to pay to replace a leaky rear main. I know its a pain in the *** and the drivetrain needs to be dropped so its not cheap, but want to know so I dont pay too much. Im in California.

don't until you need a clutch, just live with it
it's a full day job
seal is around 20 i would guess and labor 500 on a buddy deal or 800-1000 shop rate.
the drip really isn't doing any harm, just annoying

Wait until you need the clutch done and do it all at once. Not going to hurt anything just keep an eye on the oil level

Here's a breakdown
-rear main seal (buy the rear cover and it comes with the seal) ~$70
-oil galley plug (often cause of the leak and is behind the above mentioned cover) ~$10
-clutch kit with flywheel(if manual, a must) ~$400 and up depending on power needs
-slave cylinder (if manual, a must) ~$150
-labor is 7.5-8 hours in the book. so depending on shop labor rates ~$750-1000

$2K ?? Yikes. We charge less than half that to do a rear main on a Corvette.
The PCV stuff most certainly needs attending to. Crank case pressures being thrown out of wack due to a faulty PCV system can cause leaking seals to leak worse.
Good luck!

I was told that most of the oil is coming out of the rear main. That area is clean, which I was told is because the oil is dripping there so much that it washes the old oil off and doesnt allow it to build up.
