Start Up Problem

[DeanT]

Hi all, i have noticed recently that when i start the car up, especially in the cold, it makes a (and this is the only way i can describe it so bear with me!) quick scratching noise! it lasts about half a second to a second. if i turn the car off after the journey then start again 9 times out of ten it wont do it but if i leave the car for a while to get cold and i start it it does it again any ideas???

Hiya Dean... Sounds like metal to metal contact as my first idea...

BUT, could also be something quite simple - Try this...

When your motor is cold, have someone start the car whilst you locate that noise, hover over the engine to determine where this noise is. As it is a very short time you'll need to be on yer toes matey...

Probable causes -

- A pulley seal/bearing.

- A belt (daft as it sounds).

- Poor oil pressure.

- Cam/Crank main bearings (you would hear a "Knock" when warm tho).

- Cam/Crank end bearings.

- Starter motor.

Can I ask, does it rattle at cold-start?

I agree with Dabsy try that ;-)

I had the same problem last week (Exact sound). Reason:

PAS belt was too tight.

Only happened when the car was cold AND on start up
