Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Leading evidence: 'Check exhaust system - loose clamps' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check exhaust system - loose clamps' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

hi
i seem to notice a "rattling" sound when i start my car. the rattle is there just as it fires up when i crank the starter. is this normal? (2003 C2)
thanks
Don't valve lifters chatter for a couple of seconds before the oil gets to them, especially if the car has been sitting for a while? Is the rattle just as you start, or for a couple of seconds after as well?
Was this ever resolved? I've got what I think is the same thing...occurs on 75% of my startups...lasts a second or two. I'm being told it might be the starter catching on the flywheel...and that I need to replace it asap or risk damaging the flywheel.
Odd thing is it's a two month old starter!
Curious as to people's thoughts...
Trusted local mechanic when I described problem over the phone. I found several posts in the archives about this...most point to the starter. Indep mechanic confirmed that what's probably happening is the starter gears are no releasing from the "e-ring" or flywheel, and that if I let it go I risk damaging that component...which would be much more costly than a stater.
I'm just not sure HOW it can be a starter, as mine is only two months old.
Any other thoughts?
I have heard that sound described as "exhaust rattle" on startup. Mine only did it twice before I got the new motor (in 1.5 years), but does it EVERY start with the new motor. First start of the day only though. If I shut it down and start it again, it never happens twice.
My mechanic said it is the chain tensioners making noise before they get oil, but I have heard of the valve guides scenario as well. The way I understand it is that they don't all do it, but it is still accepted as pretty much "normal."
