Mike, Thank you for your prompt reply. I must assume then that it must be the timing chain tension gasket, as I can see all around the valve covers rubber gasket and it is dry. Your suggesting that all I have to do is set aside the air-conditioning compressor, remove the bolts of the chain tensioner plate, replace the gasket and bolt it back up. I don't have to worry about any springs or bearings popping out when I do so? Sounds too simple but I'll place an order for the gasket and get to it. Gregg
