How long does a rear main seal last?

[92EcoDiesel Jetta]

All this seal talk and no mention of wear marks on the crank with these high mileage motors.
That has been the single biggest problem I've had with leaking seals(new ones) on old cars, of any sort, ever.
Speedysleve and readysleeve are good stuff.

(and factory Porsche RMS are black fwiw)

Good point! My engine with 230K miles has no seal grooves worn into the crank nose journal. Nothing I can feel with my fingernails, it is nice and smooth with no pitting, just 2 light bands of discoloration. Is that just burned rubber?

As for speedy sleeves, how do you find the right size? I called up SKF techline and asked the same question and the gal who answered says if it is not listed by application, then go by the seal size. I said what about the width of the speedy sleeve? She said it does not matter. I think I'd be more comfortable with knowing the shaft diameter rather than going by just the seal size.

I want to put a speedy sleeve on the ACN tranny flange seal. The passenger side is a little pitted and leaking slightly. Do you know what size I need? It's the 90 mmm flange.

I found them by painstaking measurement and pouring over the catalogs for 020 output shaft flanges once a few years ago.
Worked real well, but was damn time consuming finding them manually so to speak. 

I like when they design stuff, or the replacement seals, so that you can alter the installed depth and get the seal on
virgin metal when there is a groove worn too.

Do you have the p/n of the speedy sleeve for the 90 mm output flange? The install tool (the cup used to hammer the sleeve in) must be deeper than usual to clear the spline stub.

The speedy sleeve p/n 99196 that SKF gave me looks like the sleeve is the right one but the tool cup is too shallow at 24.99 mm = not gonna work, unless you drill a hole to clear the stub. Is the cup strong enough after drilling a big hole in the middle?

No PN, been awhile ago, I can't even remember what brand it was but there are only a couple outfits that make em.  I think it was european.
Didn't use their tool, I cobbled something together, wasn't fun.  If I had to do it again I'd buy the sleeves and take it all to a machine shop
and have them make a piece to press them on, and have them do so.  Or, weld it up and turn it down to stock.

Solution two is swap to a newer trans, and I think that's a better option all around.

Solution three is quit buying old leaky ass VW's

Just found these new flanges for $30 from Germanautoparts http://www.germanautoparts.com/Volkswagen/Jetta/Transmission/80/2
Has anyone here used them?



If these are good quality flanges, it does not pay to use speedy sleeves, which cost more than a new flange, then you have to install it and possibly F it up if not done right.

VW had problems with those flanges the entire time the 020 was in use, and they changed them quite a bit, not just the 90/100mm either, adding the springs
behind them was a first step.  There is a good thread on it somewhere on vortex from years back, they started heat treating them eventually, and it was like a GKN CV joint where you could
see the blueing of the metal where it was heat treated.  Supposedly the very late, visibly heat treated pieces had a pretty decent rep, I never had any. 
They were NLA from VW last time I messed with them.
$30 a pop is still pretty cheap though, even if they only last a year or two.  I imagine they are chinese but that might very well be OK these days.

Make sure you get the old or new style 90's as needed.  GAP isn't specifying in that add.  brokevw has info on his site.
