Q:
Ive looked for a search on this but unsure,but i have this rattle on first start up in the morning,cold engine. When firing up u get this rattle thats sounds like its coming from the bottem pully end of engine, rev of the engine and you can hear it slightly, put my ear to pully side of the engine and moved up wards but im sure its from down below. Was thinking bout the tappets but the noise isnt coming from there. Would this be a rattling pulley as this gas a vibration damper on it{ according to etka} or is the bearins in the crankshaft going. Once warmed up the noise goes, its just that first start from cold. How hard would it be to change pulley and bearins ?
cheers

A:
what sort of year car / engine / milage??
could be any pully/bearing either cam belt, or aux belt. if you take the Aux belt off before the start up does the noise go?
A:
if it's a mk2 with ps it could be the water pump/ ps pulley that rattles on mine. They're mega expensive to replace though.
A:
does the noise stop instantly, or slowly die away? Does it get louder under load, ie when you pull away?
A:
the water pump/ ps pulley. They're mega expensive to replace though.
since when!

sorry guys a forgot bout this, its mk2 16v 88 reg, its done bout 123.000 but the previous owner said that its had a rebuid and that was in 98-99 he had the rebuild at 88.000 then. Nothing to back that up tho, no smoke out the back wot so ever, no blackness, all clear, put ur hand over the exhaust and rev the car , ur left with a clean hand!! its strange tho, cos i thought bout rattly cam cover maybe, but if u start it from cold in the morning then rev , it rattles for a bit , couple of seconds then goes but if u hold the revs it goes and when u drop the revs its quite, but when u blip the revs it rattles , let off, revs drop back, it goes. its not constant either when driving, doest make a noise when driving, just when starting on warm engine, no noise. I have got tappet noise but thats expected isnt it??
A:
I wouldn't expect tappet noise with new tappets...... check yer ancilliarys as mentioned! Otherwise have a look at the oil pickup and the other usual gremlins.
A:
Clutch release bearing? does it go away if you press the clutch.
A:
no its not that, i can hear the release of the clutch from in side the car,its supossed of been changed when i paid the garage to change the clutch. will check all bits and pieces see if any have play in them, but i have oil pump to fit on next oil change,so that will rule that one out if it still does it. Only on cold start in morning, anyway thanks anyway
