What about that pipe/hose? that run along the top of the block. As far as I can tell that pipe front to back is fine. The gasket between the hard pipe and thermostat housing is good. No leaks there. So I took the thermostat housing off today and replaced the two small hoses that run down, one on each side. Guess what?! No more tail pipe smoke! Still drips something but the white smoke I had when I started this mess is gone. Still leaks though. As best I can tell it's coming from the drivers side at the back of the motor but I can't see/tell where its leaking. I still plan on having it compression tested tomorrow just to be safe. Ok edit: still smokes. But barely. Like just enough you can see it. Looks more like oil burn now than water burn. More of a blueish tint. Either it quit smoking by 90%

Oil burn is usually the valve stem seals.

Still learning myself what hoses go where, but perchance could it be the hose that goes to your heater coil inside the vehicle?

The bottom where they meet the metal pipe seems to be fine. Really hard to tell. There just isn't enough space from the top to see what's going on. As best I can "feel" there is no leak from that area. I'm kinda stumped.

So this morning before work I took a flashlight and put in down behind the water pump, started the truck and let it warm up. Coolant is pouring from behind the water pump down the V channel. I'm guessing its the O ring.
Goes to the shop today for full timing service and water pump replacemen . I specifically mentioned the o ring behind the pump and the tech said no problem they just had to order it.
So full timing service, along with that O ring, and front cam seals for just under 800$.
Guess that's not too bad.
Stephe .

This is somewhat a common issue on the 6G7X motors with that water supply O-ring from the front housing to the tube to the rear. Once that O-Ring gives up, you will have a nice pool of coolant on the top valley of the motor. Its a easy cheap fix...just have to remove the upper plenum and mid plenum to get to it. I had this issue on my wifes full size 02 Montero a couple years ago.

The lower part? Where is the O ring in relation to that? If its possible to get to it from the top I'll call the shop in the morning and have them skip the timing stuff in my truck. Its only about 30k old. I don't really have the 800$ to spend but will if I have to. Prefer to pay for just the labor and o ring. I don't have time to fix it this weekend and leave this weekend for TN to get married. Thanks for the info!

Thanks BD. In reference for the hoses I replaced during all this, here are some pics. The first one is the passenger side valve cover. Comes from the throttle body and goes back to the hard pipe. Second is both sides of the hard pipe. Left side is behind the engine against the firewall, right by the good old rear cam seal thrust case. The right side is past the throttle body again to the hard coolant pipe. These along with both the smaller hoses the went from the thermostat housing to the hard pipe under the plenum were replaced. I bought some hose cover material to recover them as the factory insulation was toast. Stephen

If you look at the picture you will see a water tube that sits right at the valley of the motor going from front to back and sits right under that knock sensor w/ bracket. That tube slides right into part of the thermostat housing and there is a O-ring there which is most likely the culprit.

Well I'm back from Tennessee. Survived my marriage. Picked up the truck today from the shop. 937$ for essentially what is a 2$ O-ring. Had the water pump/belt/etc done with the front cam seals. So the verdict? For the first time I've owned this vehicle it doesn't leak a drop of anything! Front cam seals were solid the tech told me. Leaking pretty bad also. I did the rears about a month ago. Brought it home today and changed the oil. I can't believe how smoothly the engine runs now. No oil dripping, no water pouring on the ground. No rushing water sound every time I start the truck. With 191k it feels like a new motor. Much quieter now also. Sounds great except for what I think is a light exhaust leak. Now if I can just find the money for all new AC parts I'd be 100%. Thanks for all the grats. Stephen.

Hope you have a better experience replacing your AC than I did. I will say that replacing the evaporator and expansion valve was much easier than with many other vehicles.
