Crankshaft Oil Seal - Flywheel End

[mat1227 1]

My car is in bits and it's perfect tinkering weather, I've hit a snag so a prompt answer from the collective would be awesome

 

Right having tracked down a crankshaft oil seal that was holding me back, it's arrived but having got the old one out it's a slightly different depth - see the pic:

 

 

So my question is, as the old one seemed to sit pretty much flush with both point a. at the back and point b. at the front - as the new part isn't as deep should it sit flush with point a. or b. in the image below:

 

 

Hope I've explained this ok - I don't want to take a guess, put it all back together and have it pissing oil all over the place.

 

Thanks as always

I normally sit seals flush with the outer surface face. But ive only built my Mi that way. Rest have all been Toyotas at work

Mine doesnt leak though if thats any help.

 

Be it a cam or crank seal, i never seat them further back than flush with the outer face. If that makes sense. So its like a continuation of surface (flush with b in ur pic)

iirc the old fat seal needed to be 1-2mm proud to sit on the right spot . looks like its a thinner one that will go flush .

 

you'll see the shiney mark where the old seal rubbed on the crank . just make the new one rub on the same place.

Thanks both it's now in flush to the outer surface or thereabouts, after lots of effing and blinding to get the inner lip to behave cheers
