Hey Porsche gurus,
I have a 2011 Cayman S PDK that I bought this summer. Had a good PPI, and no issues since I have owned it. It has just over 60k miles, and I have only put 2k miles or so on it. I drive it regularly, a few times a week. Oil was changed this summer when bought. Doesn't smoke on start normally. ONE time it smoked when started after I parked on a freakishly steep parking lot which put the right bank low, so I chalked that up to oil seeping past the rings. It smoked for a minute and that was that. I routinely check the oil and haven't noticed much if any oil consumption. Was running strong and sounding great all week. I just put a Carnewal GT exhaust on and was really enjoying it!
Today, after driving it on a few errands (car totally warmed up), I put the car in reverse to back into the driveway (thankfully I wasn't in the middle of the drive up the mountain I was thinking of taking). When the car shifted into reverse, something immediately began to knock. Not a tick, but a loud rhythmic knock. You know, the a knocking sound that would make you think stuck lifter or the dreaded rod knock. The knock seems tied to engine rpm, not gear or wheel speed. It does it at idle and when backing up in gear. It seemed like it was coming from the drivers side, but I didn't spend too much time checking for fear or further damage. I backed in the garage and shut it down, but not before grabbing a short video clip. It sounds metallic, and clunky, not like a tick. It also seems like it might knock
Collapsed lifter? Timing chain? Rod bearing? I know it is hard to tell on the internet, but was hoping someone could point it out if it was very specific sounding to them. I suppose it could also be an accessory... I have half a mind to take the belt off and fire it up...
Thoughts?
