I would try leaning down the idle circuit by turning in the idle fuel mixture screws a 1/2 turn leaner and then go drive it for a 1/2 hour+ and take another look at them to see if they look more to your liking or not I don't like to see any oil, shiny, on the plug parts inside the combustion chamber, not good Two or more ways for oil to get into the combustion chambers, bad rings and cylinder walls, bad valve seals and loose valve to guide clearances and or intake manifold gaskets leaking oil into the intake ports, all of them can be fixed I would do a leak down(or compression test) test first, dry and wet. If good then I would remove the valve covers and look inside the valve springs at the valve seals to see how they appear to you if those items look good then think about checking out the intake gasket sealing Good luck, let us know what you find and do

Thanks guys, I am pretty sure that I have an intake manifold leak somewhere - how does that pull oil into the chambers? Plaz On those motors, SB Mopar L.A. motors, the intake manifold acts as the valley cover over the camshaft and lifters as well as the intake manifold but due to the bottom of the manifold covering the lifter valley oil can be sucked up between the intake manifold gasket and the manifold and heads The stock and some of the after market intake gaskets are stamped steel, not fiber so they will leak oil into the manifold quicker than the fiber gaskets do

Thanks Cab, Feeling pretty dumb for not having that one figured out... It was a fibre gasket I put on there a few years ago, but did not use any sealant..I was a bigger nube back then Intake will be off soon enough will address that then. Thanks for the advice Gents. Plaz

There is oil on the plugs but that thing is pig rich. Once you get the idle and cruise close you need to start cutting the shells off to look at the fuel ring.
I'd close the gap to .035 as well. The ignition looks a bit weak to me, but it's hard to tell from that angle, especially in a picture.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Thanks all, I am gonna try and lean it out this weekend. There is oil on the plugs but that thing is pig rich. Once you get the idle and cruise close you need to start cutting the shells off to look at the fuel ring. I give - what is cutting the shells off, fuel ring?
I'd close the gap to .035 as well. The ignition looks a bit weak to me, but it's hard to tell from that angle, especially in a picture.
What angle do you need to see - the plugs are on a bench - I can snap more pics.. Thanks all Plaz

$150 wideband setup sure helps get rid of a lot of guess work. Ya Goody, wideband is in the cards soon with the EFI install that has been ready to go for a year and just hasn't happened.. Thanks Plaz

If you are careful you can use a hacksaw or a cut off wheel and cut the shell off at the bottom of the threads. It makes it easier to see the fuel ring. I need to see the center wire and ground wire up close. You should get the oil and fuel cleaned up first and then look at things closer. I forgot to look at the timing mark to see how close that was.
