Hello,
Truck developed a ticking noise which was finally traced down to the head gasket. Weird part is that there is no coolant in the oil, no oil in coolant, and neither in the combustion chamber. The leak developed on the number 4 cylinder and at idle one could put their finger under the exhaust manifold and feel combustion product blowing onto their fingers. The head gasket has material missing where the combustion gases were coming out. All the rings look to be in perfect condition from what I can tell.
We bought the head brand new and had it surfaced along with the grooves cut in it for the fire rings(block deck was not surfaced). Fire rings and gasket came from Haisleys. H-11 head studs were used and torqued to 140 ft lbs and checked 3 times after a couple of heat cycles. The fire ring gasket setup has maybe 5000 miles on it but over a period of 3 years as the truck got to sit a lot more than I wanted it to.
Question is what to do now? I have the stock head that is unmolested and am wanting to to get a minor porting job done either route I go (i am going to do the manifold myself if I ever find time). Should i just buy new fire rings and gasket and put it all back together? Put the stock head on untouched and torque to 140 ft lbs? Get the stock head machined to go with a O-ring setup (that is if i can not just swap my cut head over already?)? Any other ideas?
Other questions I have are: 1)there seems to be combustion crossover between 1-2, 3-4, and 5-6 which almost looks by design of the head gasket...should this happen? 2) Do all styles of head gaskets have very small holes in them (I mean they don't fit the contour of the passage) where the water passages are, and what is the reasoning for this?
Sorry for the long post but I just am trying to give you guys as much information as I can.
Thanks
Adam
