I have a 2008 Honda Accord EXL V6 with an oil leak. My mechanic replaced the valve cover gasket and cam seal; but 6 weeks later I was out of oil. He says I need to replace the VTEC solenoid valve. But I'm getting the impression that it is just the upper gasket that is leaking. Honda doesn't sell the gasket for the V6 separately. Can I get a replacement gasket? The ones on ebay and amazon don't look like the one in my 2008 V6 model. Should I just use Hondabond on the gasket? Is there a way to get the gasket? Thanks! MMG
