Well I have a 94 Cadillac Fleetwood and I recently changed my distributor and o-rings and seals. I changed it the first time and had a leak coming from right behind my distributor. So I took it out and changed everything again. Right now when my engine is idling or moving oil drains from behind my distributor. I was wondering can anybody tell me the problem. Or what I can do to eliminate the leak. Is their a rig job I can do. because we tried everything.

SOunds like one of the three seals in the timing cover are leaking. This would be the water pump shaft seal (top), distributor/opti seal (middle) or crankshaft seal (lower). These seals have a teflon subtstance on the outside and must be pressed in DRY (no oil on outside so they slide in easier).

SOmetimes the top seal (WP shaft) leaks and drips down, making it appear as though one of the other seals are leaking.

The most common leak is the water pump drive seal being installed incorrectly; the seal has to face inward, there is a special tool from K-D and others have used a sharpie pen cap; I prefer the “coke” can method myself ; the important think to keep in mind here is the seal orientation ;

Notice that the black seal lip faces inward toward the block.

This is why you need the spiffy install tool .. to keep the black seal inward .. with out the tool; as you slide the seal over the shaft it would flip the black part of the seal outward and then you have an oil leak .. I cant tell you how many shops cant figure this out .. I’ve had a bunch of b-body owners contact me because the shop they were using could not stop there oil leak .. “ hi Kenny? I here you are the b-body master.. I have an oil leak my shop can’t stop” .. I know just what the problem is .. come on over … :D ..
