hi guys my friend has a 97 gt. just had new rings and a vavle job done and replaced all the internal bearings. this was done professionally and i put the engine back in the car 5th or 6th engine removal/ installation.... the car is burning alot of oil.... like 3 quarts in 500 miles. it is commin out of the exhaust in clouds. We believe that it is a vaccum line sucking oil into the intake/heads somehow and burning in the cylinder's. does anybody have any idea what this can be and where i can find a complete vaccum diagram for this car.. any help will be greatly appreciated.... im gettin desparate
