[QUOTE="Pappy, post: 438079, member: 3278"] [size=5]Time to jump in here again. It is time for you to pull the powerhead. These heads do not warp by themselves. Nor do they warp due to any manufacturing defect. There is and never has been any need to stagger the torque of the fasteners to overcome any defect in the many many thousands of these engines produced and still running. If warped, it was caused by heat. If you have followed any of my threads on this engine you will know that it is a given that the grommets under the powerhead need to be changed. Yours has all the tell tale signs of needing this done. Pulling the powerhead is a simple procedure. Fuel line, couple wires, shift linkage if yours is the old stye and around 6 fasteners. Once done you will laugh at how easy it is. Once off you can check the head and install a new gasket. Before pulling, I would check the compression and compare to any numbers you may have taken before. Are you running in cold water with no thermostat? If so put the thermostat back in before you go this far. [/size] [/QUOTE]
