Crank grove....

I suspect that my front main is going to leak due to a groved crank...

I have heard of people changing the position of the seal to avoid a oil leak how is that done?

To move the oil seal position, you don't push the seal in as far so it doesn't ride on the same groove.

You can also get a "speedy sleeve" at most industrial supply places and many automotive repair places.

My crank has the same problem. I haven't yet decided what to do... to sleeve or not to sleeve. So I'll be following this thread with interest.

Where did you get your sleeves,
if you don't mind my asking?

The source I had bookmarked
seems to have disappeared.

Silver Seal is one manufacturer that makes crankshaft repair sleeves.

I looked on their online catalog and do not see one listed for a VW. However, depending on the shaft diameter, one may work. Their online lising is for harmonic dampers, which will likely have a larger shaft diameter than that for the VW crankshaft.

82vdub:
Thank you very much for that.

Dsldub:
Yes, that was the one I had bookmarked,
It seems to have removed itself.
Thank you. I'll re-instate it.

Thanks to both of you.

So what size of Speedi-sleeve does a 1.6 crank need? Both my front and rear surfaces are probably going to need one.

I've gotten them from Kaman Industrial Technologies. They are nationwide. I'm pretty sure I got some from Napa once as well.

I called Jack today and asked him about the "grove" on the Crankshaft, he said that he has seen many many of them and that there is nothing that I should worry about.....

Your situation is better than most people (with the crank still installed). Why don't you fix it the correct way since your engine is disassembled? Take it to a machine shop and have them weld it up and cylindrically ground or turned with a diamond cutting tool back down or flame spray the OD? At work on some of my production machines I do this all the time for seal surfaces (flame spray doesn't work for bearing fits). You'll have to call around and get prices but it's well worth it (that warm fuzzy feeling of reassurance

). If your going to just put it back in I'd put a undersized ID seal for a tighter fit (i.e. instead of a 32x47x10mm seal a 31x47x10mm seal, if you can find one at your local MRO dealer).

MRO stands for maintenance, repair and operations.

my crank was full of melted berrings, grooves from the seals and a ridged block as the previous owner never changed the oil, and after 20,000 miles on the same oil ran it dry and it siezed up, ridged the block and killed the rings. I used a chisel to remove the old berrings and emory paper to get the crank into this condition below for a budget rebuild. I am now 50,000 miles into the rebuild and The engine runs perfet with no leakage or oil burning!! I just ordered new parts from jack and honed the **** out of the cylinders, good to go!

My crank had a seal groove in the front main area also.

Most Freindly Local Auto Parts Stores (FLAPS) have "speedy sleeves" or "redi-sleeves". I bought mine from car quest but Oreilly or Napa has them as well. It comes with a handy "cup" to install with.

I seem to have lost the pic of the sleeve installed.

My crank had a seal groove in the rear main area as well.

You can see the sleeve is longer than it needs to be. The pic shows me "peeling" off the installation flange. I removed the extra tall area by scoring it with a "cut off" type grinder and then "peeled" it off like a can opener.

Here's the finished product!

My cam and intermediate shaft were grooved as well so I sleeved them also. They take the same sleeves.
