im gettin a lil blow by i think, ya see theres oil swirled in the inlet housing of my turbo... im also experiencing a little bit of smoke at high rpms, im thinkin valve seals since i put out perfect compression "215 all across" an the car runs and idles fine... question is, do I use d16z6 valve seals..?? it seems that all the valve seals have different part #'s but supposedly all are interchangable "even with b series i've read"... can someone shine some light on whats BS an whats real... thanks..
