Ok, an update. I hate it when I seek a solution to a problem and the symptoms are there in a post, but the post does not contain the solution. Here we go, turned out the timing chain on the left cylinder bank snapped (bearings intermediate shaft gone bad). It also took out a piece of the camcover. A few bend valves and also the intermediate shaft was damaged. Conclusion, engine overhaul. All parts that porsche had upgraded over the last 8 years have also been replaced by their newest version. Also all parts that are subject to tear and wear (chain tensioners, ramps, bearings etc) including a new intermediate shaft, valves, chains etc. The hole in the camcover could fortunately be welded (a new cover + head, they come together, would be very expensive!). Total costs 10.000 USD. I could also have chosen to replace the engine with a used one, however this can be recepy for another failure at any time. Revision gives me a warmer feeling. Now the engine also has warrantly on replaced parts. It runs like it's new and hopefully this won't happen again..
Without a PPI do not buy a Porsche. I have been there twice and couldn't resist (foreign country buy) and regret both ;) Get it thouroughly checked out by a specialist. I am not joking! Good luck man, searching for and buying a P is always the most fun part.. except fot driving it on a beatiful day haha.
doubleb replied to doubleb's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Found it. It is actually near Cyl-1 on bank 1 (see attach). Cheers.
Figuring out what's wrong with my baby.. ;)
I've been browsing the site and internet for hours, but can't find the location for a 996 2002 3.6L camshart position sensor for bank 1 (drivers side). Anyone any clue or pictures? Much appreciated. :notworthy:
I've been thinking.. could a bad camshaft position sensor cause these symptoms? Any way to check that?
Car hasn't been sitting at all, driven every day. Could it still be a battery problem even when one bank is fireing and the other is not (doesn't even have exhaustpressure at the tailgate)? I am thinking (hoping) the cat on that side has failed and is blocking the exhaust from that side hence had O2 readings etc.. Could that be it?
Alright, got the battery recharged and fired her up again, starter motor still not turning the engine with the same speed as I am used (?) but no rattles or strange noises. With the MAF connected she dies very quickly once releasing the gas throttle. So I disconned the MAF, that helped a bit. I rechecked the codes: P0343 - Camshaft sensor row 1 P0102 - MAF When idling (very rough) I checked both exhaustpipes for pressure. Seems the entire bank 2 (passenger side) is not doing anything. No exhaust gasses and pressure from that exhaust (passenger side) at all. What can this mean? Just the camshart sensor or a camshaft or timing chain malfuntion/defect?? :o Maybe a clogged catalytic converter?? Any thoughts? Would be appreciated!
doubleb replied to thx1138jtx2's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I have the exact same car :D Happy motoring! Regards from Holland.
Tonight I drove home and 40 miles before destination cell light went on and kept flashing. Was barely able to drive home on (my guess 2-3 cyliners and able to do max 60mph). Only with very slight amouts of gas the car would keep on rolling. Car: 996 C2 Automatic from 2002. Today i connected her to my durametric software and these codes came up: 0300 - general misfire 0301 - misfire cyl1 0302 - misfire cyl2 0303 - misfire cyl3 0304 - misfire cyl4 0305 - misfire cyl5 0306 - misfire cyl6 0343 - camshaft sensor over threshold 0102 - MAF 0139 - O2 behind cat bank 1 0159 - O2 behind cat bank 2 I deleted these codes (since there quite a lot :( ) in an attempt to start te car afterwards and see what codes would come up. Unfortunately it seems my battery has passed anway.. could this have been the cause? Ohh please I hope so.. Thanks all. Regards, Sebastian
doubleb replied to beegee's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Or what I've been doing ever since driving 911's or boxsters.. just turn the gas handle 180 degrees.. Yep that's right, put it in like you were standing on the other side of the hood.. works like a charm and people stare @you like you're from another planet.. haha Good luck!
Definitely don't buy that car if the shop who is selling doesn't want you to have it checked out by a dealer (10 miles.. come on). Why don't you let them drive it to the porsche dealer and you just follow in your own car... Any hesitations regarding this should make you stop buying this car immediately, something must be wrong! Just like vette mentioned, just don't fall in love with the first car you see until you are absolutely sure it is in mint condition. Good luck man, this is really the most fun part.. just finding your car.. B)
If you want to be sure (and you should be!) have a PPI (Pre Purchase Inspection) done by a respectable specialized Porsche shop. I cannot emphasize enough how important that is. FYI, if you buy the car and the engine (cracks?) blow up in notime you're looking at 10-15K costs to repair! What should be one of the best experiences (to own a Porsche) will become a nightmare. Take it from someone who learned the hard way.. ;-) (just very persistant.. haha). Don't mess around with Durametric software (with this tool you can dig intro the computer and such), but have the DME and all electrical stuff onboard read out by whomever is performing the PPI. There is a lot that can be wrong with the car without you even noticing it and could potentionally be very expensive to repair! Just make sure you do your PPI, then you'll be fine..
