You could try getting in the bilge when the engine's running. The oil will be coming out in a steady stream and should be quite visible.

Ian I was a close as I could get to it...with all the pulleys and the water pump on.....it runs out from behind the balancer so I'm going to put in another seal tonight and give it another shot if it still leaks ....I'm done for this year.

Having done this myself, granted it was at 3 AM trying to get an engine back together, but is it possible that one of the oil galley plugs has a tiny drilled hole in it? They are drilled in 2 plugs behind the timing chain to oil the chain. If one of those ends up in any other place, bad leak will happen. Just a thought. I also thought I had a front seal leak but it ended up being this plug. Yours does sound more like a seal though. I also would look at the front seal alignment with the crank. With the balancer off, check the gap between the seal and the crank snout. Should be the same all the way around. Could the crank snout be bent? Does the harmonic balancer look like its running true?

Hope you find it. Have you talked to Crazyhorse about it? He seems to like this stuff.

I agree with the other responses. That's a huge amount of oil from a front seal. There should be no pressurized oil to leak from there unless your breather/pcv is clogged or you have a HUGE amount of blowby. Check that before changing the seal.
Not sure if an oil slinger (or lack of one) could be the problem with that amont, but it's also something to consider.

Yea, if it was a plug, it should have leaked on the floor when you broke it in. How about the corner between the oil pan and the timing cover, a famous spot to leak. I dont remember if you had a Mark4 or what. I got tired of all the silicone and holding my breath when putting oil pans on and went to the one piece gasket. Much better. But, it shouldnt leak out of there either sitting still. Youd think it would have to splash out.

I had the same problem, drove me to drinking, it was the bolt hole where the accessories bolt to just in front of the fuel pump cavity on the front of the engine block. That hole is machined all the way to the fuel push rod. Put in a bolt with sealant and wa la no leak!!! Make sure the bolt isn't to long or it will bind the push rod.

Easy there. Having a shop do it doesnt guarantee any better results. I know it sucks but in the long run, youll have much more enjoyment out of it knowing you did it yourself. Just check one thing at a time.

Get one of those mirrors on a stick and a good light, youll find it. Finding it is the hardest part.
