2.5L Oil Seperator Plate leakin' - new question
Posted 14 October 2003 - 10:32 PM
My 99 OBW's oil separator plate is leaking at 103k miles. The warranty JUSTended at 100k. It was a great warranty. At 98,000 miles, I had the VC (viscous coupler, the AWD transfer clutch mechanism) replaced under warranty. At 99,500 miles, the head gasket blew, and it was repaired under warranty. I don't know the exact details of what was done in the repairs.
My local Subaru dealer (not the one that did the above repairs) diagnosed the oil separator leak, but said that recently done repairs could NOT have caused the leak. They said I will have to pay for the repair. (the original repair dealer is 5 states away now) I didn't like their answer.
Now... both of the aforementioned repairs are under warranty, even though my warranty is up. MY QUESTIONS ARE:
Was it likely that the oil seperator plate was replaced when Subaru dropped out the (manual) tranny to do the VC, or when Subaru repaired the head gasket? Is it standard operating procedure to replace the plate? Should there have been evidence of it leaking? Does the plate often leak? Could serious overheating (from my gasket going) cause the seal to degrade?
Basically, I'm looking for ammo to make the claim to Subaru that they were neglectful of completely repairing the car when they did the VC work and head gasket work under the warranty period.
I'm in college... I don't have money, and I don't have the time to drop out the tranny, so I gotta sqeeze this out of Subaru.
It's just crazy to me that Subaru was RIGHT in there to replace/check the plate twice and didn't. I bet they saw the thing leakin, but left it so that I'd come back and have to pay for it. I'm pissed.
Any help you can give is invaluable. Thanks.

chances are, they never saw the problem. they most likely never pulled the engine to replace the head gaskets (most shops will do it in the car). i'm not 100% sure, but i don't think they have to pull the tranny to change the viscous coupler either. since you said viscous coupler, which is found only on the manual models, i'm assuming you have a manual. assuming that they did remove the transmission, did they also change the clutch? did that include resurfacing or replacing the flywheel? they probably wouldn't have noticed it if they didn't remove the flywheel, as the flywheel blocks a good view of the separator plate and rear main seal.
it is usually recommended by subaru to change the plate if you are in the area, so they probably never were around it. the plate is only sealed with rtv sealant, so eventually, like oil pans, it will start to leak. when you get it repaired, it would be good measure to also change the rear main, because you will be right there. depending on the magnitude of the leak, you can probably drive it for a while without too much harm (it may start to screw with the clutch, but it will be easy to also change at the same time).
sorry if this is a bit disjointed. please let me know if i can clarify anything. overall, they probably never were around it to inspect or change.

i think i will write a letter to subaru as suggested to see if any of the cost for repairing could be shared.
and since it's not fatal to let the thing leak for a while, sounds like i have some time to spare.
my mechanic mentioned that if the oil seperator plate is leaking, it might affect the clutch. is it possible that some small amount of oil makes its way to the clutch??

how much additional should requesting the rear main seal and replacing the flywheel each add to the quote, given that the tranny already needs to be dropped out in the above quote?
i love this messageboard.

you could probably get away with resurfacing the flywheel. that's what i did on mine with 72k miles, and have been pleased with the results.
as for the price, i can't give you a firm answer, because i did mine myself, but it doesn't sound like you are getting hosed. are you getting a new pressure plate? you should also have the pilot & throwout bearings replaced (cheap insurance). parts will run about $200 (not incl. a new flywheel). it is a lot of work due the AWD...

rear main seal costs like $6 iirc, so i don't think it would be more than $20 installed IF they are pulling the flywheel, which they need to to get to the oil separator plate.
Um, you have to either drop the tranny or pull the fans out and push the engine forward in addition to removing the flywheel in order to change either the oil separator plate or the rear main seal. If you can find a mechanic to do it for $20 installed, I want him to do my engine swap !

Pretty good chance you can get by with the flywheel if it was like mine.
I had to pay for all of that and the oil seperator myself at about 89,000 if I remember.
