Default Saturn engine front crankshaft seal leak

Hi,

I just installed a remanufactured Saturn DOHC in my 95 Saturn. I bought it from getsaturnparts a advertiser on this site. Everything appears to have gone well except for oil leak at the front crankshaft seal.

No big deal at this time, however, when replacing the seal that was new (but leaking) with another new crankshaft seal -I was surprised how easy the new seal installed in the front cover. I was able to push the seal in place with just my thumbs. There was hardly any resistance fit at all!No service tool or proper size socket was needed to install the new crankshaft seal.
The drain hole into the oil pan was clear.

My questions are :
Is there sufficient oil pressure at this seal to blow it out of the front cover?

Is there any techs out there who have noticed this front crankshaft seal is not always a super tight fit installing the seal in the front cover.

This engine cost me a lot of money ($1700) and I would hate to have my wife drive the car one day and have the seal pop out of place.

Is there a spec for the cavity size in the front cover?
Is there a sealant that I can spread around the outer edge of the seal to assure it stays in place?

The engine purrs like a kitten ,but a sudden oil leak is putting some fear in this engine install!!

REWARD EXCELLENCE!

The front crank seal is not a tight fit as you've noticed. When we installed them at the dealerhsip, we covered the circumfrence with Loctite 515 and pushed it into the cover.

One additional note if you haven't done so is apply sealer to the inside of the crankshaft pulley or the pulley washer to prevent oil leaking at that point.

Never done it, and I've literally removed hundreds of thousands of crank pulleysfrom S Series cars. Certainly couldn't hurt I guess, but not at all necessary either.

I've just completed the rebuilding of 99 SL2 the only problem I'm having is the front seal seams to be leaking. My Haynes manual talks about the depth of the front seal. Currently the new seal is flush with the timing chain cover, is this an issue? Is the seal a one time use? I had to replace the original cover with another and used this same new seal?
