Gastket Failing. Unfortuneately I will have to throw my hat into the same ring. Currently my car is running and fairly well but I am seeing a leak into the coolant system. The FelPro gasket that has been retorqued has lasted about 4000 miles. I am not gentle on the car but it is apparent that the leak is contaminating the coolant with gases. I must bleed the rad every time I take out he car on the road. Idling causes a break down in circulation and the car starts to overheat. There is a positive pressure in the coolant system at all times even after cooling down over night. My can of Heldite has dried out and I have a new can on it's way but the Post Office in Canada is on Strike. I will have the Heldite shipped to FFO and will have to change the Head Gastket when I am in Nashville or on route when I am at Bob Martins in Kentucky. I will go back to the Stock head Gasket and use Heldite. This method of installation has never failed on this car yet. I was impressed with the FelPro Gasket and felt that it was a better option with less cleaning when removing the head. Live and learn. TonyK. Grimsby Ontario Canada.
