New EQ Heads - Small Amount of Oil on Top of Pistons (Boroscope Camera)

Hi everyone, I have an 01 Durango which has the same 5.9 as you Ram guys. I initially found out about the plenum oil leak issue here so I figured I would ask you all your thoughts. Truck has 110k I had a ton of oil consumption before the plenum fix.

After doing the plenum fix from the forums I was still getting ping, figured it was my plugs since they were iradiums and probably too hot. Anyways I was going to clean the top of my pistons using mopar combustion chamber cleaner and change my plugs. Well good thing I decided to inspect before with my boroscope. I saw small pockets of coolant in a few of the pistons. So long story short I got new EQ heads. I couldn't tell how the coolant got past the heads, gasket looked fine and and I didn't see any cracks, figured probably a hairline crack that just started on both sides but again no evidence.

Installed the heads and the whole intake over again. Also redid my plenum and used blue loctite. Ran the car for a short trip (about 5 miles) then decided just to check with the camera again the following day. I had cleaned the top of my pistons perfectly mind you, took a ton of elbow grease. So I check the pistons 8 1 and 7 I see small amounts of oil. Heads are new and the only thing I did was spray a bit of fogging oil before putting in my new plugs (2 secs of spray).

So now I am baffled, I have no clue why I have oil showing up (after a short trip) on my piston tops. Plenum has been fixed. Here r some photos

Give it a bit longer of a run. 5miles or so isn't long enough to fully heat up the internals to get a proper ring and oil seal. Not surprising to see a little oil on there. Some of that is likely even combustion and pcv emissions pulled in with air.

Get it up to good operating temp, make sure there's no external leaks and it's not overheating, take it for a good highway run and see how it's sitting after that

Thanks for the reply dapepper9, So far I have done at least 3 short trips the other two were about 7 miles and 20 minutes or so. I took another look in two cylinders today still seeing some oil. I then looked down the intake and I could see I light amount of oil on that that new bottom plate. Took a napkin and screw driver and def have some oil on the bottom plate (thought it was my eyes) Very light coat but its there. My PVC is pretty new. Is it normal for the emission system to put so much oil back in through the intake like that?

Idk that I'd call it normal but it's not abnormal. You can install a catch can and clean the intake then watch it for awhile and see if that eliminates the issue. Comp test wouldn't hurt either if you don't know how it reads right now
