replaced clutch in my 85 back in Nov.( with new transmission mount )_ car has run great but recently heard a intermittent rumble/ rattle first heard when turning hard left and accelerating
in trouble shooting i checked timing belt tension it was all ok
used a long screwdriver as a stethoscope but could not pinpoint
during that I found that would go away when i lifted up the engine a bit
lo and behold my ac compressor pulley was touching the frame due to seriously worn engine mounts had to drive car and ac does not work anyway so i cut belt .
I then noticed a higher pitch squeal/metallic jingly sound at approx 2700 to 3200 rpm no sound below that rpm and maybe not as much above but hard to hear over regular engine sounds.
is coming from front area of engine
replaced both mounts yesterday and have the battle scars to prove it ( also working on a black car outside no shade in Texas when heat index is 115 is the pits but hey I am an alfisti ). made sure all was tight no loose things to make noise all in adjustment
still have same noise
can find nothing loose and i even stabilized the ac compressor pulley even though not turning in case it was a rattle/sound from there as it would turn on its own when the sound would start .
after much study it seems like sound may be coming from water pump bearing
I replaced the Water Pump New from centerline last August /Sept but noticed when i first heard the grumble rattle during initial troubleshooting that ,that the belt was WAY too tight . adjusted
after yesterdays . wrenching and still chasing the elusive squeal /rattle I noticed that the fan pulley assembly has between a 32nd and a 16th play . Car is a daily driver could a pump bearing go south that quickly due to over-tightened belt ? If not is there another direction the all knowing and powerful alfabb folks could point me towards ?
