Just finished up replacing the head gasket due to a compresion leak into the radiator (foaming the antifreeze). Start it up and now the rear main is hemorraging oil out of the bellhousing.

Anyone out there replaced their rear main seal "in the car"? Gonna have to pull the trans, flywheel to get to it. What a PITA.

The only thing more difficult about doing it with the engine in the car is getting the seal to seat properly while under the car or in the wheel well. I would suggest getting a housing gasket as well and just take the whole rear main seal housing off, then you can put the seal in the housing outside of the engine bay and it'll be much easier. Just check and recheck then recheck again to make sure the seal is uniformly seated into the housing. Sounds like you pretty much know what you're in for. Make sure you have some FIPG and some grease for the inside of the seal.

Found my rear main seal to be "cocked" in the seal housing, bottom side was flush with the rear side top was pushed in to the front of the retainer. Never expected to see that, but glad to see that it was definetly bad, Found my axle outer boots trashed too, got the manual trans back in late this afternoon, going to finish it up Friday/ Sat. Still need to replace the water pump. I could press the old seal in the housing with my hand, new seal required a seal driver.

thats good to hear, at least you have a seal driver. i found myself using the old seal as something i could hammer against haha. now i know how ghetto i am.

browsing through an autozone yesterday and i saw a bottle that said Rear Main Seal Repair. it says it stops leaks on the rear main seals and all types of engine leaks. I have an oil leak that i believe is coming from the top the the oil pan that is connected to the block. Im about to reseal the top of the main oil pan with the toyota sealant on my next oil change. Should i also buy the bottle, or will i be waisting my money on the $10 of Rear main Seal Repair???

I would just reseal it first, don't go putting all kinds of bottle remedies into your engine... they just swell seals that are now going to wear quicker.

ok thanks for the advice.
