The pitting looks like casting marks imo. The other two look blueish which would mean an issue with oil burning, as is indicated by blue exhaust. And if you didn't work out the air bubbles in the cooling system when you filled the tank, you would get some settling in the coolant level. Not to disagree with the mechanic, but I don't really see symptoms of head gasket failure nailed down at this point, but a whole lot of burning oil. And that is a very pricey repair. Now, a combustion chamber flooding with oil will definitely cause the engine to misfire.

ok, it seems to be adding up now, as the mechanic says he would change the rings and grind/replace valves, change gaskets etc.
the big question i want answered however, is...would the shorter plugs installed and used for 2 weeks or more e responsile for this oil egress and malfunction?

I would GUESS no, though it probably wouldn't help with the engine performance either. The tube gasket is above the head, the plug screws into the head, so I figure that wouldn't have anything to do with oil egress, but I'm just snowballing here. I would imagine it affects the spark timing because it's higher up in the combustion chamber, maybe even shorts to ground, could screw up valves.
Changing rings means he thinks oil is getting into the chamber from the lower portion of the engine, probably poor cylinder compression would be a result.

I disagree that it doesn't have a blown head gasket, that one cylinder wouldn't be that clean if there wasn't something going on to make it look so pristine and clean as it is compared to the others.

If the rings were bad it would be blowing blue smoke all the time it's running and not just at startup, bad valve seals are almost always the responsible culprit for blowing blue smoke only at startup.

That clean silver cylinder head is the classic sign of head gasket failure.

There's also significant oil infiltration the combustion chamber, and it is a problem unrelated to the head gasket. I think AU Seeker nailed down this one.

[QUOTE=Seymore Butts;3427718]That clean silver cylinder head is the classic sign of head gasket failure.


It makes sense... coolant cleaning the area???
Honest question, is this an already stablished, well known sign of HG leak?
(I have a low mileage 2003 V6, so far so good)
Thanks
Carlos

Carlos, the water content of the coolant fluid cleans off carbon deposits very effectively.

I believe it. Between the abrasiveness of coolant and the scalding hot liquid under pressure, I get it would be very effective at cleaning carbon off of a head
