[QUOTE=HeyYou;3520035]Yep, that is the ONLY way to correct it. The tolerances are measured in thousandths of an inch, and single digits at that.....

Do you know the tolerances allowed?

 

[QUOTE=NeilP;3520110]Not on the newer motors. Info is likely in the service manual, but, I don't have one. Best bet is to pull the head, and have a look. Problem might be obvious. Don't take much to prevent a good seal.

 

Just removed the left head (looking from the front of the truck). The gasket is the top left (which should be the driver side), yes that happened!!!!! Well at least I took a straight edge and tried 0.13mm and it wouldn't go through, testing for warping on the block. I am still going to check the head one more time just to make sure, it still good, but I imagine it is because I never got to start the engine. The leak occurred when I was just adding the coolant. I am going to call the dealer and see if they recommend replacing the gaskets although I never started the engine.

 

Yes. Replace the gaskets. They have been torqued down. They are not re-usable.
