not sure where the vtec solenoid is on 6th gen v6s, but if you find it, give straight 12 volts when the engine is on. that will pressurize the oil.

a vtec solenoid will be located close to the camshaft, it only has one wire going to it through a plug. give that wire straight 12 volts when the engine is running. it wont mess up anything, but just dont it for more than a minute or two. but also remember, this will make the oil leak even worst.
