Title: Weirdness on the way to work
Post by: sKrEwBaLL on 24 October 2003, 10:08

I was driving to work this morning and I was booting it in 3rd on a sliproad and then changed gear at about 6000 revs and then suddenly I heard this strange buzzing noise, it was loud and quite high pitched.  At first I thought it was coming from the engine, but it seemed to be coming from the dash, probably the clocks.  I slowed down a bit and tried to figure out what was going on.  It carried on for about 5 minutes and then someone phoned me and I explained to them that I thought my car was shafted, I said listen to the noise...  as soon as I said that it completely stopped!!

Any ideas as to what the noise couldve been....??  ???

Cheers

Neil

its not high pressure, its a lack of pressure at high rpm's (i think!)

could be caused by a bit of dirt getting sucked into the oil lift pump in the sump which is enough to reduce the oil flow when the car is under load

I had this same problem on my cab. It used to happen at the same point every journey, so I put it down to interference, on the radio,  from a RADAR on the airfield next to the road - however it happened on another road one day, and I pinned it down to my speedo - it used to make the high pitch whine at 62mph+. I took the speedo out, and cleaned the coupling between the enertia disc and its housing, put it back together and it has never happened since. I reckon it could have been a bit of grit or dirt causing it to vibrate at higher revolutions.

The only thing that worries me is that I was red-lining it just as it happened  :(

Just checked my oil and it is very low, which is worrying as I topped it up about 4 weeks ago.  I havent noticed any puddles of oil under my car and I dont think it is burning oil (theres no smell or smoke from the exhaust).

what grade of oil are you using?

i find i need to be using 15w40 any lower and it'll just drink it!

Title: Re:Weirdness on the way to work
Post by: sKrEwBaLL on 24 October 2003, 12:21

I think it 10W-30.  Is this not suitable..?

Hey screwball
I've only ever heard the oil pressure warning buzzer once. That was on my first 16v years back, scared the sh!t out of me when it started (ear piercing even over my sounds!).
Anyway it's usually a bad sign, especially when using oil as you described. It turned out I had blown my head gasket. Have you got any sludge in your expansion bottle?

Yes tobz, I papped myself as well.  It should come with a warning light as well so that at least you know what the feck is going on.

The headgasket has been replaced about 5000 miles ago, so I dont think it is that.  I noticed my oil level was VERY LOW so I nipped out at lunch to get some oil.  At the same time I noticed a little puddle of oil underneath the car, so I think I've got an oil leak.  Would low oil cause the buzzer to go off?

I havent noticed any sludge in the expansion tank.

Where is the oil likely to be leaking from...?

well if there is a lack fo oil then it cant circultate enough especially when redlining, hence loss of pressure as it starts pumpin air!!

10w30 is too thin, goto 15w40

get VAG silver synta

I bought some 15w40 oil from Halfords, didnt want to spend too much while I've got the leak.  They were doing 5L of Castrol GTX for a tenner so I got some of that.  Its funny how the Halfords own brand stuff was more expensive..   ???
