I think the hole you are refering to is just a peice of gunk. Posting some pics would be nice, thanks

Just got off the horn w/ Ekess, it sounds as if there is a gasket mis-alignment to be dealt with. I think he on the right track, but a tad bit inexperienced, which is how we all started out.
Good luck with it Eric.

it's raining today so I can't do much at this time. I am a little concerned that have some standing water in the combustion chambers some where that could possibly be rusting?

Just pull a plug(s) and turn it over. If your really worried spray some WD in there but I think youll be fine.

Here is mine the "this side up" should be visible between the middle of the two sets of runners. kinda where your 9th injector is. if you see it in both those areas, then they should be on correctly or on backwards. But man that amount of water out the exhaust seems more like a water jacket issue then a simple gasket mistake.

If you stick you finger into the thermostat hole twards the passenger side you will feel the tubular intake runner in the manifold. its straight in where these holes are on the front of the intake. If you did get into a water jacket this is where you did it. So see if the #1 cylinder is filling with water, because no coolant ports are close enough to intake ports on the head to where I would think a simple leak would do this. If the gaskets were missaligned I would think it would go in the oil before it would ever get into the cylinders.

however if you did infact hit the water jacket it will suck the cooling system dry real quik. and still excess coolant will bypass the rings and go into the oil.

Update: pulled plenum and I had a ton of water up there. Once I got all of the runnners off, the gasket seemed to be well alligned so I decided to put some compressed air to coolant system via the manifold. It seems to only leaking from the 7th cyclinder but I can't really see where.

Any ideas before I go any further?

did you torque the manifold correctly ?
I think it would be obvious if the gasket set was on wrong.

my buddy did the torquing of the bolts and I didn't pay enough attention like I should have. It is extremely possible that a combination of things came into play such as: cleaning the surfaces with with a wire brush + no rtv around the water ports mixed with a bad torque sequense spelled disaster for start up. I will be taking the base to a local machine shop for his opinion about the manifold base.

Hopefully if I get **** about it this go around I won't have the same issue. Otherswise the motor is going to get pulled and completely gone through with an of a ceratain 1 peice manifold and some new heads, come hell or high water.

thanks to all from providing help

well round two ended up the same. Water is still leaking around the #7 cylinder. I bought new gaskets and made sure to put some right stuff around the water ports. I also took the base to a machinist and he said it looked fine.

What else could be going on here?

Here's one pic of the manifold gaskets, that's the way how they are supposed to be there:



Now that you mentioned the #7 cylinder...are you sure, that the cylinder head gasket hasn't broken? The #7 cylinder is the most likely to have a leak in the head gasket. Almost every time you blow the gasket, it's that one.

Here are a couple of pictures of my previous '87

this guy is right. But talking with the OP, he is saying coolant is getting up into the plenum as well. I've never seen a TPI do this with a blown head gasket. Almost wondering if he has a coolant hose hooked up wrong on the plenum or TB and its sucking coolant out of the cooling system.

After further review, It's a head gasket I really don't know how this car ran so well with it blown- or ready to blow. I had been expriencing some coolant loss prior, but not a huge amount.


So where to go from here? Engine has 130,000 so I guess I know the best answer would be to pull it and do a full rebuild
