OK, I can see a trail of coolant running down the head behind number 8 cylinder but it looks almost like it is coming from the corner of the intake manifold, thats not possible right? Because the coolant ports are more towards the middle right? /forums/images/graemlins/thinking.gif I figured it was the passenger side head gasket from seeing the water but I notice that I am getting a small trail of white smoke out of the driver side exhaust for about 10 or 15 mins. after start up, opposite side to where I see coolant running down the head. /forums/images/graemlins/confused.gif /forums/images/graemlins/dunno.gif My 406 has been wanting to run warm for a long time but has gotten worse fast in the last month or so. I checked the water this morning and it was low so I am definantly burning or losing some coolant somewhere but the oil and water have not mixed yet. I have replaced everything in my cooling system except for my water pump but it seems fine and it's brand new anyway. I have narrowed it down that it has to be something internally in the motor with either the intake manifold, the head, or head gasket(s). A mechanic that works on our semis at times is coming to help me do something with it but I need to make a decision if it is just one head gasket, leave the motor in, and replace it. Or if it is both gaskets and I would be money ahead to just pay him to help me pull the motor out and rebuild the top end. /forums/images/graemlins/doah.gif What should I do? /forums/images/graemlins/dunno.gif What are some problems you guys have had with overheating issues, head gasket issues, anything that sounds related to my problem? Thanks.
