a little oil in the ic piping is normal (not pouring out) but a coating inside due to crank case venting back into the accordian hose before the turbo, Did it smoke when it was running last? describe it if it did.? when my turbo blew the oil seal, it was just a puff at first then next day it got worse as i let off on boost to an idle at speed it would smoke bad. bad enough i parked it for repairs. I havent heard of anyone actually having to install rings on these supras due to blowby, Not saying it dont happen but its not common that i know of? i guess it depends on your cash flow and what you plan is with the car, if your going for seroiuse power id pull it, but if your basically stock, i guess i would mic all the cyinders and look for sloppy pistons and if therewith in tolerences, slap it back together?? i got 157k on stock block and ive been at 10-14 psi for 2 yrs now woth no smoke issues ever..cept the turbo..
