However, I do suspect that my chain tensioner/guides need to be replaced… occasionally, during the initial start-up only, and on cooler days (35-55F), the rear end of car sounds like metallic marbles in a tumbler for a split second… then settles down nicely, and, as I said during the initial start-up only.
Perhaps, could it be the starter/flywheel gears stripping at engagement… or even the catalytic heat shield? I've not been able to detect anything loose underneath to give off that kind of noise/vibration.
Daily driver 8-9 months of the year, using M1, 0W-40, 5-7K change intervals… "clean-of-visible metal" oil filters after removal.
Any ideas, comments or suggestions are certainly welcomed... and most appreciated ;-)

Marc, thanks so much for the reply...
What symptoms were experienced with your problematic VarioCam solenoid and actuator; were the components easily accessible, or did the procedure require engine removal?
This disturbing, rapid, staccato-type, brief chatter really sources like a momentary slack in a chain which buzzes over another surface… then, as you mentioned, is quickly and totally dismissed as the oil pressure builds. It might be difficult (intermittent) to duplicate for an independent or dealer to check out.
What might be the consequence (and fix) for the chain and guide 'wear' continuing this way? This has occurred perhaps a dozen times during the past couple years now… with increasing regularity when cool temps.
Would I eventually expect to see bits of metal or plastic in my drained oil pan or old oil filter?
I don't really think it's the cats, but could be... and have not experienced CEL, yet.
Yikes, almost 268k... FrankZ, Chicago - Monday, 10 June, 2013, at 2:20:15 pm |
