Antifreeze in oil pan?

I'm trying to run a list in my head of where my leak could be before I end up tearing the entire engine apart and rebuilding this bitch again. This engine has never been turned over yet and I recently replaced the timing cover. As I poured antifreeze into the radiator I could hear it spilling into the oil pan at a pretty decent rate. Where the hell can this come from?

I figure it has to come from one of the following:
- Heads
- Cylinder crack
- Block crack
- Timing cover/water pump

I don't think it could be the heads because the spill rate was too high to be a leak from either a torn gasket or improper fitting. It damn well better not be a cylinder or block crack because I just had this block boiled and blueprinted. The only thing I can think of would be the timing cover but I can't see how it would transfer from the water pump to the timing cover. There is the +/- 2 inch area at the front of the oil pan that hooks to the bottom of the timing cover but it is separated from the water pump by that plate thingy. This is the first time I've ever used a Fox style timing cover and water pump so maybe I put it together wrong...

Any ideas?

Pulled the oil pan and watched from underneath as water was poured in. It comes pouring out of the rear drain hole coming from the lifter valley. I figure I must have the intake gaskets on backwards or something. When I pulled the plugs to check compression all kinds of water poured out of the #4 and #7 cylinder too... I guess I'll yank the intake off and watch to see what happens when I force water through there. Hopefully it's just a gasket problem.

Yeah I was working on doing a compression check but that's when I discovered the water coming out of the #4 and #7 cylinders. Decided I didn't want to chance it with that kinda gunk coming out so I pulled the intake and heads, not a big job.

But... I regret to say that I discovered what was wrong. I regret even more to admit it was my fault. See... I had lent my larger torque wrench out to a friend so I couldn't torque it with my remaining wrench due to it only going to 90 ft-lbs. So... rather than go to 90 and wait till I got the other wrench back I just left it as is until he gave it back. I had gone on to other projects and working on other parts of the car when I got it back and apparenlty forgot that I needed to torque the bolts down.

Unfortunately... there was water in there long enough to cause significant rust damage to the decks and parts of three cylinder walls. I'm gonna tear the engine down completely tomorrow and take a look at all the cylinders and pistons to determine if I will need a new block or will be able to simply hone out the damage.

Damn I'm dumb...

That's a darn good idea... maybe I'll start tagging the parts or something from now on.
