Oil leaking from exhaust manifold

[Toddishere]

I have a 2007 Ram 1500 with the 5.7L Hemi that has been sitting for several months. When I finally went to start it, it fired right up, but it started smoking almost immediately as it warmed up. It smelled like burning oil, and I found oil leaking from the exhaust manifold where it connects to the rest of the exhaust system.


Is this something that will clear up on its own—perhaps just dry seals from sitting—or is it something more serious? I’m about to clean it up and do some maintenance so I can start driving it again. I didn't have any issues before I parked it for a bad fuel pump, which I recently replaced (though the new pump unfortunately has a bad sending unit). It runs fine and there is no loud ticking, just the smoke

If you have oil inside the exhaust I would suspect valve seals or valve guides.

Another thing that can put alot of oil into the intake manifold is an old, worn out PCV Valve. You be surprised how much oil the stuck PCV Valve will allow into the intake ports of the cylinder heads.

How many miles are on this motor? Being that the motor is nearly 19 years old I would put a new set of valve seals in it and go on with my day. You can install valve seals without removing the heads. You can do this by pressurizing the cylinder with compressed air to hold the valves in place and remove the valve springs and seals. It's a relatively simple straightforward task.

If you really want to verify your diagnosis, disconnect the exhaust from each exhaust manifold and see if it's wet with oil. Then stick a flashlight and a bore scope in the exhaust manifold and look for wet exhaust ports and oil trails.

It has 208k miles and I've taken good care of it other than letting it sit for a very long time I'll try your suggestions I appreciate the response

valve cover gaskets?
