Looking for idea at why this may be. I recently had my original engine replaced by a re-manufactured engine and had a relative do the install. During the break-in period of the new engine, noticed an oil leak. Discovered leakage on left valve cover, wasn't torqued properly, same with oil pan. Tightened both those down and that seemed to fix leaks in those areas..
Now, what I originally thought was an just exhaust leak on the right side manifold turns out to also be leaking oil. I've got UV dye in the oil and I've confirmed that the valve cover above and the spark plug socket next to the leak are dry. There's a head bolt next to the leak but it's tight and oil is not coming from the bolt. I had pulled the exhaust manifold bolts and noticed one of them (double-ended stud that the AIR pipe bracket mounts to) was covered in oil. Without pulling the entire manifold off, I cleaned off the bolts, cleaned up the threads, and retorqued them and the leak persists. I can see the oil collecting and bubbling right where the exhaust manifold meets the head (There is a gasket in place, btw). It then leaks down and burn off of the manifold.
Any idea why oil may be leaking from here? Engine seems to run fine, otherwise. I don't have oil and coolant mixing anywhere so I believe the head gasket is ok.
I don't have the means to pull the engine myself but I can pull the manifold off and investigate further if I knew what I was looking for.
