Matthew Cheek Says: i just put oil in this car 9 dollar a quart synthetic and dont have more than 5 miles on the oil i dont wanna waste it...do i just reuse it?2. roger Says: I can understand the problem but 9 dollar a quart synthetic is a waste of money ace. Go buy some cheap oil in quarts dump your crankcase oil in your oil change bucket close the drain plug and then dump the cheap oil in your engine and transfer the 9 dollar stuff into the cheapo empty quart bottles After the intake manifold gasket is replaced and you get the engine up and running use the cheaper oil to help wash any debris from the engine work into the crank case and then change the oil at a few hundred miles or what ever dump the cheap oil in your bucket and put the good stuff back in. Piece of cake..3. Amanda Says: I have never seen a car that had oil that flowed through the intake manifold. You may want to drain your antifreeze so it doesn't leak all over. My opinion is if you don't know that, you should hire a mechanic.4. bikerwoody Says: I am not familiar with the vehicle, but I've never known a car to have oil flowing through the intake manifold.
