oil on pistons
compression check will test out how much pressure is inside the cylinder but will not test how long its there, so check it by doing a leakdown test.... if there is no oil in any piping then 1 its not the turbo unless the turbo is spooling to much boost for the engine and will cause alot of blowby, but as stated before theres no oil in piping, so either valve stem seals or ringlands. in between the sleeves is coolant so we know its not the sleeve.
also let the car idle for a hour lol, turn the car off and verify no oil is in the cylinders. then do this take all plugs out take the harness off coil packs and injectors off as well and crank it. Dont forget to put a towel over the cylinders. if it gets oil in it doing this with no compression i can only see the rings being bad. If the valve stems are missing itll smoke all the time and if they were bad and not missing itll smoke all the time as well just not bad. rings were bad itll smoke at a high rev but at idle lower oil pressure and the oil spitters underneath the pistons arenet shooting oil as fast.
thats what gets me about ure motor. all four shouldnt go out all the same time unless you didnt have the crank balanced and or you put the rings in the incorrect spots. also only do compression test via dry test, meaning no oil in cylinder, with the oil in the cylinder itll cause the compression to go up since the seals good lol

i was thinking valve seals but dam for a bunch of them to go bad to get oil on all the pistons
let me ask you something, you know how theres vents that go from the valve cover to the head and idk where those vents in the head go to, is there anyway threw those vents that oil can get to the cylinders because of the turbo oil return line on the oil cap
the vents are routed like a v they are like runoffs sorta they route to the pcv system and about the oil return, ive always thought that was a stpuid idea because of heat and because of the oil sump system..................... i just dont get why all 4 cylinders............... do a leak down test you will find your issue...
when u take your spark plugs out is the oil on top of the spark plug or just in the cylinder, meaning only on the electrode and the ground strap. another thing that could have happened was you have a lean spot and blew al the rings from the heat
theres only oil on the top of all four pistons and the plugs are dry oil free
k, i know you dont have a pcv valve lol ive had a lsj ss, but to me u need to do a dry compression tests. but tell me this when you first start your car in the morning does your car smoke heavily or no if not the seals wont be bad, becaise if the seal is bad then the oil will seep into the cylinder more when the car is turnbed off,

bro its hard to tell, leave your car running for the long period you said, then make sure no oil is in the cylinder once the car is off, then leave it off for about 10+ hours, start the car, if it smokes valve seals are bad, this is the easiest way to check stem seals. Piston rings will let more oil pass by as with more rpms because less compression but more oils pressure.
Anyways, I'd almost certainly bet the valve stem seals were installed incorrectly.
This is gonna sound dumb but what oil did you use to break in the motor?? If you read the total seal te h page they say not to use synthetic oil for break in due to lack of piston ring seating... I have a buddy of mine that built a camaro and he has very similar probe cuz he used mobile one as break in oil... Also those gt35r is known for oil consumption... I have a friend who put 2 on his skittle and they smoked... Went back to a forgot what turbo, prob gone... Who did your machine work? I highly recommend Phil and Richard at south florida machine shop... Great guys.... And blazin what happened with the coilovers?
