wierd problem? im stumped..

[turbo2nr]

ok i was putting the car into my drive way, and letting the car warm up.. i see a little white smoke , i think nuthing of it maybe condensation.. also i hear a wierd noise. like a hi pitched squeal, kinda like a blet squeel but more hi pitched and sounded motor wise.. as i reved the car it got louder and and sound like it was moving faster..

by now the car was up to operating temp. and the white smoke was still apparent.. so i pull the car in and decided to check the plugs. lose the tension form spark plug #1 and oil comes spraying out the spark plug hole.. WTF? the rest of the cyld were fine, clyd 1 had oil in it.. but i say no blue smoke form the exhaust..

did a comp test. i got 180 across all 4.

the only thing that was not normal was that my wastegate is going so i was driving on the hi way the other night and my boost spiked to 15psi, i had good fuel tho, i was still 11.7:1 on the wide band..

now the part that stumps me i put the plug back it, start the car up and the noise and smoke is gone!. the compression is still 180 across all 4. and the car sounds healthy , idles fine...

my setup is a ka-t t4. on 8psi. ka has 113k on it..

any clue on what when on?
