I got the manifold off but there are no signs of cracks. Is there anything specific I should look for? There are some signs of oil around the upper exhaust manifold gasket but I've noticed that before. There are also signs of soot around the inner rim of the 2 bottom gaskets. Not all the way around but in different areas as if it was blowing slightly outward. I'm not sure if it was there before but it wipes away easily like it is recent. IDK. ANy thoughts? I will get a new set of gaskets tomorrow but I'm still lost here. Any thoughts or opinions will be much appreciated.
