starting a new one now after my findings, so here is a basic rundown of what i have done so far.
compression test 148=150 across the board
leakdown 5-8% leakage
checked for vacuum leaks/exhaust leaks all clean, checked all plenum and intake bolts all tight
fuel press 43psi
pulled downpipe did not see any traces of oil, cold side is clean no oil and shaft play is normal
pulled crossover pipe to inspect if any oil inside, its clean
new denso 02 sensor installed
pcv valve is ok
new plugs installed

so what happens is i start the car no smoke at all,so that tells my seals and guides are ok since there is no puff of smoke at start up like a dripping seal overnight, 5 min after idleing it's a bluish smoke that is so toxic it will kill a man in a matter of minutes!! and i can not nail down if its oil or just dumping fuel from a stuck open injector, as i have read some old threads that raw unburnt fuel "can be blueish smoke" and to not confuse it for oil, also oil changed a few weeks ago, maybe 10 miles on the oil and an hour of idle time and the oil stinks of gas,and spark plugs showing no signs of oil,plugs are very dark like its real rich, any ideas??? i bought the car not too long ago, current chip is 93-alky TT chip #60 injectors, im considering just trying a entire new chip and all new injectors, im about to lose my mind, im running out of things to check!!
 
Blue smoke is normally oil burning. Does it smell like fuel or oil?
If it was an injector the plug on the bad cylinder would be black as coal.
 
Before you "lose your mind", how about posting some data, such as SM, PL, FP, etc?
A bad temp sensor, air temp sensor, map sensor, and as mentioned a bad maf, come to mind.
 
02 milivolts 680-750
l8 30
af 04
bat 13.9
ine 128
blm 136
mph 00
clt 172
ats 97
r 875
tps .42

I have the ls1 maf and translator, I unplugged the maf while running and it did stumble so does that mean it’s working or maybe not working properly, smells like pure fuel and have not tried another maf

Sure it isn't oil in the DP burning when the DP heats up? Possibly the turbo leaking oil through the exhaust side into the DP?

I have checked for oil in there and don’t see any or smell any, it starts to smoke after 5 min from a cold start so I don’t think that is long enough for oil temp to come up and push oil past the seal, after 5 min engine is just barely warm, and the fact that I can’t smell oil just heavy rich fuel
 
Pics of engine, maybe something out of place

Does the turbo have extra play in it?
 
Are your cc's moving smoothly or are they stuck or sluggish?
 
It doesn't now or it never showed it?

Did you check the settings in the translator to make sure they are correct for the MAF you are using?
 
Thanks for the plug oix. They do look quite fuel fouled. One on the bottom right looks a little greasy. Is it?
