No apparent loose or busted fittings/hoses but a couple of still pictures showing the leak after I put water in the reservoir. Also a video which is a lot more telling. Any thought? I haven't researched the plumbing diagram as of yet. Thanks.

FWD end (you can see the rear sway bar):

No visual signs from up top. It sounds like it is running through the hose that runs down from the tank. Since whatever I pour in comes out w no pressure I'm thinking a connection somewhere or fitting vs head gasket.

 

Thanks for the info. I bypassed the tank and poured water directly into the hose running down the backside of the engine (that was connected to the bottom of the reservoir) -> water came right out as in the video. ����

 

The hose that bottom feeds the water pump is good. Maybe the interface of pump to block? It's a pita to find the origin.

 

Agree but I bypassed it and it still leaks; can't be the tank.

 

That's exactly what I did. PITA but can't be worse than gearbox install w engine in!!

 

Just behind the alternator there is three small hoses and tubes that can fail.....Hard to see but a possibility.... It was my case ;-( . Called the water pump housing.

 

JP good point Thanks. Those are mostly hidden until alt is removed? I might try some fluorescent dye; impossible to see up in there and flows out quickly.

 

Right....those lines are above the wp.

 

You still raise the level of the fluid into the engine block and water pump housing...I think I miss something here ???

 

Sorry, I don't see other possibility of leaks here....

 

The leak is not coming from the WP. It is somehow coming from the top of the engine and running down. I'm going to take off the inlet plenum and other stuff to see if I can find what is going on. Within about 30 seconds of pouring 6-8oz of water in the bypassed hose leading to the bottom of the WP it will run down the FWD side immediately adjacent to the gearbox bellhousing/engine block interface. I recall some coolant line here....

 

90% sure you lost the fitting on top of the motor by the oil cooler. Engine will need to come out...

 

Glorious. How the F did that happen? You got pict/diagram?

 

The glue turns to powder and out it goes! Can you wrench? This can be a 500 fix or 5000.
