truck is the 2005 one in the sig.
this week end My truck sat for three days and when I moved it out of the grauge I saw the pink anit freeze on My white floor, not much just a few drops on the floor, anyways I found its coming from the drivers side at the back where the Cylinder head and block meet, I cleaned it up started the truck and no leak I drove it to work today and ran it hard a few times and saw 13psi of boost (41*F day) and parked it at work , just looked at it and no fluid leak at all.
Has anyone heard of a head Gasket leaking a little coolant during cool down and fix it self?
BTW the most boost I have ever seen is 13.5psi with 17* of ignition advance no KR and I run Meth inj., I wouldn't belive this to be anough to lift a head or blow a head Gasket.

 

Are you sure it isn't the Radix intercooler connections? Is your bleader valve closed all the way?

 

Yes I'm about 99% sure but I will take a really good look with a mirror and bright light later this afternoon. Lokking from the top of the motor I can't see any fluid on the Back of or top of the head just at the head to block meeting point.

 

check the coolant tubes that run from head to head also

 

Thanks man, I'm going to check everthing over tonight.

 

I had the same problem on the passengers side. The coolant tube that connects to the heads under the intake was the problem. One of the welds where the tubes are connected was cracked.

 

Ok, it has not done this but only once, I looked all over the motor last night and the only sign that there has been a seep is where the head and the block meet on the drivers side rear, but everything is dry now. WEIRD
