Crank oil seal

[helga592]

Hi 1.9 watercooled running on lpg
I had the ckank oil seal replased (behind the flywheel). Its just come back from the garage thrid time the guy has done. It's still leaking i'm new to t25s is this just one of those things part of the charm of the van. I'm reluctant to go back again he is such a nice chap and seems to know his stuff.
Cheers

Why not.

Its not fixed

Hi mate - You need to get this sorted. I think a leak from this seal can contaminate your clutch plate - which means that your clutch will sleip, and not clutch!! You will also need to keep topping up with oil.

I thought this seal was an engine out job (or gear box down at least).

Glad you have got someone nice...but it really needs to be sorted. Unless of course, it isn't that seal that is leaking and there is another problem. I would thank the chap for his efforts so far, but request that it goes in for a full investigation and proper resolution.

Only my thoughts

No sorry....it certainly isn't one of those things! these can be repaired sucessfully and without issues. Don't get me wrong, these can be a bugger and you never really know until everything is back together wether the tension spring and the seal lip (if it has that type) has come adrift or not.
Usually it is possible to be fairly confident of a good repair...lube the lip and crank end, keep it square, knock flush. I've had several occasions where some sort of glue was required on the outter edge to bond it in the recess (locktite bearing lock...that sort of thing)
PS in the first instance oil on the clutch will make it judder when pulling away.

Engine probably has loads of endfloat hence why he keeps doing it.
Buy an engine instead.

Simon,

Please can you explain end-float, and why it means a new engine?

(in simple terms!!)

Endfloat is where you reverse your van too far into the sea and your engine fills up with water!

[Titus A Duxass]

Everything gets worn and sloppy and generally floats about a bit.
The end of the crankshaft is floating about in its bearing, usually because of wear and tear.
With it floating about the seal can not form a good stable seal around the end of the crank, therefore allowing oil to seep out.

ahhh...but as Top Gear proved with the Dampervan, VW's don't suffer from endfloat...they have end-SINK!!! (or is that just diesels..???)
Not workin' today?

Titus - ta!

No, not working today... Slight accident involving a ladder... Or lack of it to be more precise!

The crankshaft movement is from front to back Emm, as opposed to up and down. This is supposed to be taken up by a shim pack at the front end of the shaft between the shaft and the back of the flywheel (or drive plate on automatiques)

Right, ive had this problem too. It may well be your flywheel is scored where the seal sat therefore will always leak. You can get a new flywheel or get it resurfaced at a machine shop with rock hard metal/ hard chrome ( what i did). Or your crank or case is slightly warped so when it spins small gaps appear around the seal or hair line cracks in the crank case. Each time you need to change your clutch

[clartsonly]

are you sure he is actually changing it.. I spent about four hours trying to undo one of the bolts on the flywheel and gave up in the end.

also as the above post suggests the haynes manual tells you to wet and dry the crank.

My oil seal has been needing done since last year but I stuck some Lucas oil seal stuff in and months later it's only leaking a few drips a month. Compared to the slick that used to be there it was less than 10 quid well spent. If the mechanic is actually replacing the oil seal and it's still leaking give some of this a try. If the engine does have this endfloat then perhaps you'll get a few more miles out of it?
