What are the most likely spots for oil leaks on the front of an M110? I'm working on a truck with a real bad leak or leaks. First thing to do is valve cover gasket. Also power steering pump gasket is hard as a rock and leaking.
The primary leak seems to be engine oil though, and lots of it. I'm assuming front main seal but it's really hard to see. I'm not very familiar with this engine. There appear to be some side covers in the block under the exhaust manifold? Do these open to oil passages? The front most one is soaked with oil, but maybe it's just coming from the F.M. seal. Anything else to consider before tearing into the crankpulley?
