Head Gasket Testing

I recently replaced my egr delete and oil cooler because I had signs of oil in the coolant. I purchased this truck in the winter and prior to the replacement of the parts I was not puking any coolant. I am not sure if this is because it wasn't hot or I wasn't towing with it at the time. Well fast forward to this summer and while towing my 3000 lb boat I puke coolant. The coolant and oil temps are always within 10 degrees of each other. Also, I am noticing when I decelerate I hear that tea kettle sound that many hear with bad head gaskets. I am looking for advice on the easiest way to test the system. I recall reading a thread that stated you could run a piece of tubing spliced off the overflow lines into the cab, throw a pressure gauge on it, and monitor while driving for pressure over 16 psi. Is this the easiest/proper way to test for bad head gaskets?

since you have done the egr delete you may just want to take the lid of the degas bottle start the truck and see if it puffs out the bottle, also check your coolant for fuel, if you have an injector cup starting to leak it can also give some head gasket type symptoms.

If I get a puff out of the degas bottle when I start the truck what does that mean? Something wrong with the egr delete or head gaskets? How do I check coolant for fuel with some kind of coolant test kit?

That's how the Ford techs do it. T fitting with a hose and gauge coming off the T into the cab.

This was the kit I purchased:

03-07 6.0 POWERSTROKE FORD EGR COOLER BLOCK OFF KIT: eBay Motors (item 360288217672 end time Sep-06-10 15:50:22 PDT)

Is it possible that something is wrong with this kit?

Hey sorry for the delay in response, but what I understand is if you get puffing from the degas bottle you have pressure in coolant system. So since the egr cooler is gone your not going to get pressure from that source so possibly a head gasket (lets hope not) but if you find fuel in your coolant (I don,t know of an actual test other than looking in the degas bottle or draining a small amount of coolant from the system) and looking and smelling the coolant for signs of fuel. If you do find fuel in your coolant it could be an injector cup which can be replaced with the head on the truck. You also may want to get the truck scanned to see if a cylinder is running out side of its tolerances, such as low boost on a cylinder, ect.

the way you test for combustion in fuel system. install remote start and take off fuel filter cap. if you get bubbles through filter housing, you have combustion
