hiya. have recenly bought an alfa 156 2.4jtd saloon. with engine noise. the crankshaft pulley wheel had been repaired badly and wan't running true. fitted 2nd hand pulley wheel which made a difference for a while,but is getting noisey again. Have just put brand new crankshaft pulley wheel on but still got engine noise. Can only describe as a ticking rattle coming from bottom left of engine veiwed from front of car. I now know what it isn't as i had engine running without crnkshaft pulley wheel / aux belt. so i know it's not steering pump / air con pump or alternator. Anybody got any ideas or had this problem themselves?
