So long story short, I bought my project car with no engine in it and bought a built engine off someone from the forums. I've finally installed every mod that I want to so it's time to get ready to get the car tuned and painted. It really only has idle time on it but it's been burning oil every since I got it running, (I know this because the smoke coming out of the exhaust and I have pics of the exhaust ports if you want to know the extent of how much oil its burning, spark plugs are also fouled). To find out what is causing it to burn oil I did a compression test today to see how the rings are.
The Results:For the dry test each cylinder was exactly 180, with throttle WOT, and for the wet each cylinder was exactly 210, with throttle WOT.
Just wondering if these results were enough to confirm that it's the piston rings and enough to warrant getting this fixed. Should I do a test to check the valve seals regardless, (a leak down test I believe)? I'll answer any more questions you guys need to know because I want to make sure the engine is absolutely running right before I take it to the dyno/track.
Spark plugs look like this on every cylinder
Dry Results
Wet Results (About half a cap full of oil)

thats just carbon build up. It wont stay clean all the time.
. I just want to make sure I'm not missing anything thinking about this. The only way for oil to get into the combustion chamber (which it obviously is because my plugs are fouled) is to either get by the valve seals or rings right? I'm thinking that maybe just the oil rings on the pistons are bad and the compression rings are good which is why I have great compression? I bought a leak down tester so I'll do that this week and report back but I'm just looking for other thoughts as well. Is there anything else it could be that I'm overlooking? I think I have all the information that's important answered earlier in the thread but ask me any questions you might have.
