Hello everyone, I'm new here and hope to get soen good advice from yall. I have a 2006 highhy awd with close to 270k miles. The car has been trouble free up till this point. There seems to be a big leak coming from near the oil filter. Because theres so much in that area it's hard to tell for me where its coming from, im fairly sure it's not the valve cover gaskets as theres no oil coming from them. Its leaking all over the exhaust manifold and burning smoke. I had a mechanic check it out and he says it might be the heads leaking, now I'm not a mechanic but wouldnt that also mean I'm supposed to be leaking coolant as well? I will post a pic soon.
