alright in the final stages of turbocharging the car, however its pissing oil out of the sandwhich plate, now i havent took it off yet (no time) but i was thinking it would be the plug screw. would teflon tape fix this? or would anything else be causin this? also on a side note, o2 sensors, do the thread patterns vary from wide band compared to narrow band? any input would be great. alohaz.

 

normaly NB and WB sensor have the same bolt patern
M18 x 1.5 mm also WB need bigger hole because the end of the sensor is bigger
check carrefuly
for your oil leak, you should take if off to see, it could be a crushed gasket, a bad plug..
regards

 

thanks, im taking off the sandwich plate tomorrow, wating on my wide band to get in. i just hope that the threads of my 02 bunge arent messed up cause thats what its looking like, any way thanks.
