PICS Need help figuring this out Head and intake
Ok tore it down and it looks like I may have more problems then just leaking head gaskets. Found out the head gaskets where leaking on Numbers 7 and 8 cylinders. So.... Why do my heads look like this? I have a slight coating of oil in the intake but the PCV pipes and hoses do NOT have hardley any oil at all in them. I have left them up side down for 2 days and not a drop anywhere and nothing pooled inside. Rings? Why are the intake runners looking like this. Why do the combustion chambers look like this? How bad did I get F'd on this engine or is this normal??? I can't belive it is. Heads are LE2, bottom end is a 383 eagle rotating kit. Here are the pics. Best guestimates as to what my be going on and ways to test it? Please give me your best guess I had it built because I don't set up custom engine combos.
ALL of the exhaust ports look like this

Well looks like your burning oil. The one exh valve thats white looks like its been getting hot. Judging by how dry the intake runners are there might be an intake valve sealing issue. Causing the carbon to build up in the intake runners.

Lloyd did mill the heads because he told me the combustion chambers are now like 52.5 CC The intake is stock. But there was NO oil around the intake gaskets at all either on the head flange, intake flange or either side on the intake gaskets. they are compleatley dry. By the way this is only about 4k to 5k miles on this thing. all street use.

I would send the heads out to a "reputable" shop and have them one overred. There is a possibility that the valve could be damaged or at least have carbon build up preventing it from acquiring a good seal. At worst I could see excessive cam lobe wear and lifter damage in addition to valve and valve seat damage.

They just look like they have been running bad. Burning oil creates alot of nasty carbon build up. I'll have to find some pics to show you of some nasty LPG engines with bad rings lol.

Well the tune had just been redone and seemed to working really well. Yea it's really long story as to what happened. Short version is even long lol. Turns out yes no thread sealant on the head bolts which lead to a small steam cloud on a hot start up and lead me to think the head gasket failed. Tore it down to short block and found the heads looking like this. No oil in the PCV system anywhere, but light oil in the intake. It seems to be a general consensus that maybe because the heads where milled and the intake is stock that maybe the intake gaskets were leaking but I see no signs of oil any where on the intake gaskets. I am really starting to think it's the rings but I am not someone who ever messes with bottom ends or even really does anything to the heads other than I could bolt them on. IDK for sure yet I still have to take this thing to someone and let them actually inspect the bottom end and the heads and cam and see what has been done and if it can be undone with out needing new parts. Just been a PIA since the time I said ok to build it. Original builder out sourced it and I don't know who built it but at this point I have to find someone and fix F' ups.....again.
