|Plugs all look the same, I cannot tell anything from looking at them on which might be the problem cylinder(s).
I've had the plugs in and out a few times since starting it, since they were new I cannot really see one that had an issue.
Oil has since cleared out. I did install megan downpipes, and there was some oil in the exhaust, but that has since burned off. It's had enough idle time and test miles that its not anything else left burning off.
But the oil point got me thinking about something, there was a decent bit of oil in the cyl for lube when I pressure tested them, I'm wondering if I pushed oil past the copper coated headgasket and screwed up the seal.
