Small oil leak at rear of manifold?

[rmm]

I seem to have a very small oil leak coming from the lower rear of the right manifold by the bolt on my port '88 Crusader 454. Appears to be coming out between the block and manifold. It is minimal, like a couple drops after running for 2-3 hrs. The odd thing is this leaking oil seems pretty dirty and the oil per the dipstick is still pretty clean. The motor burns no oil, have about 1500 hrs, FWC, the manifolds I just figured out are original as I found the date stamp.

Any input on this? Minor leak just keep an eye on? anything else to look for? or have the mechanic check it out?



Thanks

if you are talking about the right exhaust manifold, it is likely to be from the rocker box cover. The dirt is likely to be collected as it flows down the cylinder head & manifold.

Could also be a manifold/ block leak. Easy to fix (though the distributor has to come out).
