I checked the thermostat and water pump seals and do really see anything wet. Could there be a head gasket issue on this side? The motor runs great and doesn't smoke so I don't think anything is getting into any combustion chambers. Is this a common issue? It's not alot of coolant since the level hasn't changed much at all. Any ideas? I don't want to replace the head gasket if I don' thave to....Thanks! | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | Coolant can leak out the edges of the head gasket. If the engine has been worked on recently & the head was removed you could pull the valve cover & retorque the head bolts. If not or that doesn't fix it put in a can of Bars Leaks.

DO NOT loosen the head bolts an retorque them. Instead, set your torque wrench and torque (tighten) them again at the full recommended setting. Use the pattern shown in the shop manual. If it doesn't stop the leaking, I would pull the head and start over with new a name brand head gasket.

I have what my daddy called "cold water leak" where it seemed the water appeared after it got cold...
That said you may want to check the "gooseneck" and see if its warped letting some water out...either hot or cold.
I know my V8 is different but the gooseneck did the same thing on it. I could see coolant on top of the intake but it only showed up AFTER parking it and letting it set a few days. Well, I pulled the gooseneck and it was warped. Put on a new gooseneck and the leak went away. Apparently the neck was expanding when hot and would not leak...then do the opposite when cold.
So, perhaps your gooseneck is warped and coolant running down and being blown back where you see it????
Just a thought. You just never know!! | | | | | Joined: May 2010 Posts: 6 New Guy | | New Guy Joined: May 2010 Posts: 6 | Thanks guys, these are all good thoughts. My plan is to first pull the valve cover and go throught the head bolts with a torque wrench. It seems like the path of least resistance. I'll also try to look at the goose neck. Could try the Bars trick, just a bit cautious with a new radiator core and all. I don't want to gook things up if I don't have to. | | |
