    You can figure it out. That one plug that is wet seems out of place so I would focus on that cylinder. It also seems more white than the others. The blue smoke that you showed a pic of should make the plugs foul a bit more. All the plugs dont look to bad really. If it is a leak from the rings your compression would be low as well since both the oil ring and compression rings wear at about the same rate. It could be a worn out cylinder but that really is rare I believe. You can do the leak down test to rule out the bottom of the engine. Then rebuild the top. You might as well rebuild the top anyway since its the cheaper and easier way to go first vs changing the bottom.

    My bad for not being more specific on my build. This build has less than 400 miles maybe even 300 miles on the top end. The heads came from hinson that I supplied to him and are ported. I think the seats were clearance for extra lift as well if the time ever came. He also installed the seals to accept my XP cam. So that means all the other gaskets are new on the motor and GM which I put together. Indeed cyl #2 is my culprit. Cyl 4 has minor white on it too but nothing crazy. So those are my culprits on why it smokes blue. More so cyl #2 at the threads are wet. But what gives they are right next to each other. Seeing my compression number in #2 is higher than all the others due to it being so wet with oil. The funny thing is I was watching a tv show this weekend on flipping cars and they were working on an old vette. Well it smoked bad at idle and startup and they were like well that's the culprit of bad valve seals. So they pulled the plug and it was wet with oil like mine. Then showed how the seal was wasted. I thought to myself well isn't that nice! Of course it was a totally different design lol

    But I will have to do a leak down test on that cyl and a known good one in the front.
