Hello again
I rebuild the engine about 1000ks back and now the new crank seal has started leaking. there appears to be no obvous damage to the seal itlsef and yet theres oil allover the flywheel and on the sump. the seal came from 126 fan and made sure it was oiled before installaton. all the bolts on the bearing holdr are tight a there's no damge to the paper gasker behing the holder
thanks
