I have a fully built and boosted 2200. Im leaking oil from the crankshaft seal. I have replaced it twice and its still leaking.
Is there any special procedure im missing?
I remove the pulley, remove the old seal, pack grease behind new seal, insert new seal, replace pulley.
Could the turbo be heating the oil up, and changing its viscosity drastically to make it leak past the crankshaft seal?
This is a very frustrating, small and constant leak.
Any Ideas
Thanks
Are you seating the seal all the way? Is it leaking between the seal and the block, or seal and crank?
make sure the spring in the seal is staying where it is suppose.

Do you have an underdrive pulley?

Its seating flush with the timing cover. You asked if it between the block, no, its not the rear main seal, im talking about the one in the timing cover.
It leaking between the seal, and the pulley.
The spring is staying in place, that is why I packed it with grease. The two that I have removed, still had the spring in it too.
No I do not have an underdrive pulley, just stock crank pulley.
Should I try to press it on further with a rubber mallet, or a 5lb sledge with a block of wood.
Could it just not be seated all the way, to seal on the pulley?
Okay, how many miles are on this engine? I ask because something you won't believe tends to happen to engines with higher miles on them: The lip of the seal tends to wear a groove into the part they come in contact with. This happens most-commonly with the harmonic-balancer & the like, resulting in less than ideal contact of the lip with the surface in question, and causing a leak. Fortunately there is a cure: Many companies make replacement seals meant for "groove-worn" balancers & what-not that corrects the problem... It's only a matter of searching for it to get it, which would mean using the right keywords, of-course.
Go beyond the "bolt-on".

In the bolded text. That's why I asked if you had an underdrive pulley. I know a lot of times the aluminum pullies will get a grove worn in them real quick causing a leak. I think there's someone on the boards here that will put a steel ring on those to help with just that problem. That's why I'd asked. Check to see if there's a groove in the crank pulley from the oil seal, or whatever it's touching.
