1139.0. "funny noise" by SHIRE::GOLDBLATT () Mon Jul 09 1990 08:23

    My Golf has developed a peculiar noise when the motor is running cold.  
    It sounds like someone inside the engine is beating on an empty tin
    can.  The noise is not too loud, and completely disappears when
    the motor warms up.  Nothing's loose, at least I can't find anything
    obvious rattling around, and I don't think it's this because the motor
    runs very smoothly when cold.
    
    Any suggestions as to who's trapped in the engine ?

1139.1	Put some oil in it!!!	IOSG::MARSHALL	Harry Palmer	`Mon Jul 09 1990 10:55`	11
	Low oil level => low oil pressure during first few minutes of running => Poorly lubricated camshaft/tappets/rocker mechanism => tapping noise. Problem compounded because (unless your car's very old) you've got hydraulic tappets. There is usually a "whine" for the first few seconds of running, until the oil pressure in these has built up. Maybe this is louder now as well? Don't rely on the oil warning lamp on the dash; that won't come on until the oil's low enough to have already damaged the engine. Check the dipstick weekly. Scott

	If the oil level is ok, you may have some blocked/partially blocked oil passages. Try adding some gunk removing additive to your oil before the next change. Warren

	� 1139.3 Sounds like "piston slap" to me!! Is that better or worse than "piston broke"? ;-)
1139.5	Any one who smokes Silk cut!	REPAIR::ATKINS		`Fri Apr 24 1992 11:25`	11
	I've got a funny noise! It can be heard at high speed,it sounds like the alternators whinning,but I could be wrong.Does anyone else have this problem?Is there a cure? Also do you get more road noise from low profile tyres,than from ordinary tyres?(Are pirelli P600 classed as Low profile?) Andy...The-motor-hypercondriact.
1139.6	Oh, you haven't got one?	DCC::HAGARTY	Essen, Trinken und Shaggen...	`Fri Apr 24 1992 16:38`	3
	Ahhh Gi'day...� It's the turbo.
1139.7	No turbo.	REPAIR::ATKINS		`Mon Apr 27 1992 10:27`	10
	RE.6 As you say I haven't got a turbo(but I was thinking of getting a courtney turbo,but at 2500 pounds it's a bit expensive).A small question.Does the alternaters revolutions increase with Rpm's? Any ideas?? Andy....Lucky-lucky-Leeds-boo-hoo-boo-hoo....MUFC...

	>> <<< Note 1139.7 by REPAIR::ATKINS >>> >> Does the alternaters revolutions increase with Rpm's? Well take a look under the bonnet, see that the alternator pulley is attached by a rubber belt thingy to an engine pulley and then tell us what YOU think. :-) :-) Stevie. (Oh alright then, the answer is yes.)
