Ok did compression test and surprisingly its 160 all 4, everyone i know has different stories on what it could be but im just leaning at valve seals. cold starts it dont smoke and after it warms up smokes alot.

i know there is threads on this but i dont wanna base my situation off theirs.

some valves are wet and some are dry but even the ports with the dry valves seem to still get wet, also the pistons get wet not alot just light as from what im not sure.

Mine did the same thing. It ended up being that the second compression ring below the top ring was collapsed on 1 side. The top ring were free so a compression test showed normal results.

does this sound right, if my intake valve seals are bad would that suck in oil and make the pistons wet and plugs coated in a little oil? and blow it out the exhaust making wet ports? also if it was a ring problem would i have excessive blowby cause i have very very little air that pushes out the pcv vents on the valve cover.
 
Good compression does not necessarily mean the rings are good. You should do a leakdown test to be sure. If all is well there, then look into the valve stem seals. Is there oil on the back side of the intakes?
