I see the line. there is oil on the exhaust manifold nuts and such which are above this line. I got the exhaust manifolds off and am taking off the intake manifold. the nut and bolts on the intake man are somewhat hard to get to. you either need to use tiny tools or have very tiny hands to get the bolts on the bottom. I bought a useless manual online (read the thread about ebay manuals). so I'm just winging it.
