  1. Iv recently purchased a Porsche 966 C4S with 55k miles with a rear end wreck, it had sat for at least 2 months with out a proper start up. upon arrival i did an inspection, it had a few pulleys bent including the tensioner pulley so i can't necessarily run the serpentine belt with out removing the engine and replacing it, air box was broken so it had to be removed including the mass airflow sensor. exhaust was untouched. no damage to the block. after preparing it i started the car for the first time, it ran good i listened in no ticks or knocks everything was running fine ( it ran with out a serpentine belt nor a air box/mass airflow sensor) i ran it for a few minutes then it started to have a slight tick and gradually increased to a steady ticking, i ran a OBD2 test for fault codes, the only codes i got was a mass airflow sensor fault and the throttle body code, other than that no other codes. i read around online i should replace the oil, because it could have been a stuck lifter or sticking valves. i changed the oil with 5w40 and added a valve cleaner to my gas, ran it a a few times for a few minutes at a time not to over heat my engine, at the moment i don't know if this may fix the problem because i can't necessarily drive the car, if any one can tell me if I'm at risk of loosing my engine if i do fix the engine up drive it around, or i should fix it up and take it for a drive and it may go away. or i should just take it straight to a mechanic. Please let me know your thoughts.
  2. My 04 CS has developed a new issue, anyone have any ideas with this... When the engine is started and running, doesn't matter if its started fresh or has been running hard for an hour, there is a distinct sharp ticking noise, very rapid, that sounds like its coming out of the throttle body on the top front of the motor. I have been through the threads and heard the various postings of the dreaded scored cylinder wall or slapping pistons, this sounds nothing like that, this is a sharp ticking noise and its not coming from the cylinders. Near as I can tell the noise is coming from the top center of the motor from or around the throttle body or even right below. its not loud either, you can only hear it if you open the hood and lean in. No faults, No engine light, some very very small rough idling when coming to a stop sometimes but runs ok, no burning oil, no leaks as far as I can tell anywhere. im stumped, 75K miles and I know its overdue for service. I am going to change coils, plugs, oil and filters soon so I wanna tackle this noise while I am doing that I just don't know where to start.
  3. Hi Porsche enthousiasts! I am reading a lot since a few days on these forums, especially the 986 ones there i am a fresh owner since march of this year. There my Boxster is driving perfect i am wondering about a weird noise at cold startup and sometimes but not often after a restart after e few houres of driving. I have already asked this at two Porsche specialist over here but none of them are able to tell me exactly what it is. The only thing they do telling me is not to worry about and to drive the Porsche wihout sleepness nights. The first one is sure that the noise is well know also on the 996 engines and will not go away and not will harm my engine eighter. The second one thinks about the timing chains but also, nothing to worry about. I don't now what to believe or todo with it. I want to know where the noise is coming from so here is the link of a soundclip attached. The noise is on the driver side and at cold startup for a few seconds, than it goes away and my car is running perfect. Hope someone can help me over here. Thanks a lot guy's !! Startgeluid_Motor.mp3
