Lower intake manifold leak obviously. I was hoping this wouldn't happen to me before I got rid of the car 11 months from now. I'm not going to spend the money necessary to fix it right, I'll get rid of the car first since it is an extra car anyway that just keeps me from putting miles on my other car. I'm going to try some Bars Stop leak with more frequent oil changes with cheap oil and see if I can keep going at least a few more months. I would like to drive it until next spring if possible. After a few short changes I'll do another UOA and see if I should keep driving it or get rid of it. I plan to donate it to a local charity that also has a full time mechanic and teaches people in need how to fix cars. I don't want to keep driving it if I'm going to wreck the engine so I'll play it by ear and see how it does. I want it to be fixable when I donate it or it will be of no use to them. I was going to play around with a few different oils before getting rid of the car but that plan is now over. I'll probably waste my last 4 qts of Mobil 1 on it since I don't want to use them in my other cars based on their UOA's. What is the cheapest acceptable oil I can get? I've checked the local ads over the last week and haven't seen any good deals on cheap oil. Lots of synthetic on sale but no cheap dino.
