Strange knocking sound...?
Sometimes when i drive off with a cold engine, it knocks a little bit on low revs (below 2200). OK that's a bad valve i thought, or the cam time variator. But the strange thing is that *sometimes* when i have the AC on it doesnt knock wink is'nt that really weird? Sometimes i can hear the knocking on low revs on 1st and 2nd gear but not the others. Hmmm, broken frame layer or other layering?? But then it would knock when i brake and put the pedal to the metal simultaneously as it is more resistance for the engine, right? Very odd knocking sound. Damn it is too noisy in the compartment to record the sound on minidisc or something otherwise i could demonstrate the sound with a MP3.
Ooh, and when i "engine break" the car it makes a little scrapeing/rattling-like sound that might have something to do with the knocking!? But that on the other hand can have something to do with the low level of brake fluid (i know it is REALLY stupid to have little break fluid, fillup coming soon), or the low level of powersteer fluid (again i know it is REALLY stupid to have little powersteer fluid). The scrapeing/rattling-like sound can be either the brake servo och powersteer servo that is dissapointed with the air in the system, right?
I have checked the cams and they are not worn down, all valves seems OK and all the belts are changed 9000 kilometers ago.
Any ideas of what the hell this can be is rewarded with a cyber-hug eek!
