I certainly hope that you have used NOTHING but genuine HONDA COOLANT in this car. Using the "green" stuff may have eaten holes into your cylinder head. It is an aluminum alloy that is vulnerable to the chemicals found in many coolants. THERE IS NO UNIVERSAL COOLANT!! I have seen many Honda cylinder heads that look like Swiss cheese due to improper coolant usage. You MIGHT get lucky IF you find someone who is willing to re-torque your cylinder head, according to the sequence and procedure listed in Haynes manuals. This MIGHT straighten out the warped head and re-seal the gaskets. You can do this yourself with a little bit of determination. If you try this and it DOESN'T work, then you will have to remove the head, have it cleaned and lightly resurfaced, unless it is severely warped. In this case, it will have to be heated in an oven and restored to it's original shape. Obviously, you will need a head gasket set (kit). Use ONLY genuine Honda cylinder head kit and ONLY genuine Honda coolant. Use the internet to price these things out. You may as well replace the timing belt and water pump at this time. After all this work, the engine should last another 150,000 miles. Good luck!!
