  1. Hi. I had a problem similar and this turned out to be the duelmass flywheel. Regards.
  2. Hi 5700ci I am sorry, you have reminded me that I should have put some feed back on my post. Oops sorry again. Yes the problem is now cured. There were two problems that I discovered I am not sure which was the culprit. The first was the valve timing. I decided to remove the plastic plugs in the camshaft covers and remove the oil scavenging pumps from the camshaft covers. I then rotated the engine with the crankshaft nut to align the cam shaft marks. The Durametric tester indicated that the misfire was on bank 1 so I decided to move the adjustment by moving the gear on the camshaft slightly towards the center of the elongated slots in the gear as the bolts were to the extreme left in the slot. This brought the timing marks into alignment. I can only assume that whoever owned the car before me had done some work to it but it had not been done correctly. I am not sure why the misfire only showed up on tick over when the engine was hot???? The second problem I found when I was checking out the valve timing, and which I hadnt heard before, was when I switched the engine off there was the sound of a bearing or gear still spinning down. I thought it must be the clutch release bearing, so I removed the gearbox to change it. I discovered that the flywheel was in two separate pieces. The center rubber cushion of the dual mass flywheel had completely broken up and there was no signs of bits in the housing, its a mystery!!! I wonder how it drove with no symptoms like the clutch slipping or jerking. The thought is whether there was an imbalance in the engine that was detected by the sensors and the ECU tried to compensate for it causing the engine to run rich and cause a misfire. Regards lib.
  3. HI. Thanks JFP and Wayne Thats very useful stuff I will remove the green plug and cautiously try and make progress. Thanks very much Regards Lionel
  4. Hi All I have a 1997 Boxster 2.5 man trans. RoW. I have the Cyl. head off bank 1 and the chain to this bank has moved from the camshaft gear. The question is how do I find when piston number 1 is on the compression stroke and not on the exhaust stroke without taking the cam cover off bank 2. Would I check for piston #4 coming on to compression or is it piston #6 coming on to compression that would indicate that piston #1 is on the exhaust stroke which would line up on the crankshaft pulley. I hope I have been able to explain clearly? Many thanks Lionel
  5. Hi PK Thanks for your info. The Porsche centre pu 6 new coil packs in a few months ago and said that would solve the problem but alas NO This is a real stinker of a problem just cant seem to get yet. Regards Lionel
  6. Thanks Loren I will check out the wiring and let you know. Regards Lionel
  7. Hello all I have a 1997 ROW Boxster 2.5 which when it gets up to temperature will misfire at idle and put the cell on. When I first had this problem of misfire at idle the Durametric showed misfire on bank 1 and cam adjustment fault. I subsequently removed the variocam adjuster and changed the slipper shoes as they were slightly marked but could not find any thing wrong with it. I fitted it all back together and road test. te car went really well but after a few miles i stopped at a junction at idle the engine started to misfire again. when I checked it with the Durametric I discovered to my amazement bank2 had the misfire and bank 1 was OK!!!!! I then fitted another o2 sensor to bank 2, I had previously fitted one to bank1 I also changed the maf sensor as durametric showed fault with maf hot film. Today I checked with the Durametric and find that the fault has changed back to bank 1. I have done nothing to the car other than clear the faults and test it again to See what faults will show up this time. I have added the fault codes in the hope that someone can interpret them for me. P0102 Porsche fault code 115 - Hot film MAF sensor P1530 Unknown DTC: 1530 P1115 Porsche fault code 13 - Resist. limit O2S ah. of cat. conv. B1 exceeds limit value P1119 Porsche fault code 5 - Resist. limit O2S ah. of cat. conv. B2 exceeds limit value P0301 Porsche fault code 508 - Misfire cylinder 1 P0302 Porsche fault code 510 - Misfire cylinder 2 P0303 Porsche fault code 512 - Misfire cylinder 3 Many thank for reading my tales of woe. Regards Lionel
  8. I guess that's possible, but I don't recall changing any wires or plugs per say, just added the small bulb into the socket that was fit into the back of the tachometer and high beam light. They worked appropriately when I put them in. There do appear to be some connectors floating around that don't appear to have a home (so I've placed electrical tape across them until I can trace them either by the wiring diagram or manually over the winter. I've also ordered a replacement switch via eBay (US $40 vice $205 at other store site) - hope it works out - same part number and all. Would you know the correct positions for each of the wires that come off the back of the light switch? I was deliberate in marking them, but some were "fused" to say the least. Hi Skip I have a wiring circuit that may be of some help . Hope I can get it to copy ok . Regards Lionel Sorry about this, I just cant get the diagram to show. I have uploaded it , it dose not show anywhere. Lionel :huh:

  10. Hi Thanks I kept feeling around looking for a 17mm nut the same as the lower fixing. I now know what to feel around for. Many thanks wvicary. Regards Lionel :D :renntech: Mine was a 10mm Allen Wrench on a 3/8" socket that I used. The only way to easily access (somewhat sarcastic) the upper bolt was over the top of the transmission - seems odd, but there's a heck of a lot more space than directly from the front. This way I could guid the socket into place by feel rather than simple trial and error. Hi Skip. Thanks for your reply. Yes mine happens to be a 10mm too. Phew what a job! I still havent managed to get the allen bolt loose. I have tried with the 3/8 sockets but it is to tight to move. I bought a 10mm 1/2 socket but the long extension is to long and of course the short extension is to short?? I dont know where to go from here Ill have to try and think of some thing. Thanks again Lionel

  12. Hi I'm glad you sorted it out. I am trying to remove the starter from my 1986 carrera 3.2. I have removed all the wiring and slackened the lower fixing nut but I cannot get a spanner in on the top fixing. I should be very grateful for any help on how to remove the starter motor. Thanks Lionel
  13. Thanks Mike I shall have a look on eBay, hope I can find it. Sounds quite tricky. Thanks again Lionel ;)
  14. Hi, me again I am in the process of putting it back together again. I have refitted the camshafts and the variocam mechanism, which by the way I didn't find anything suspect. Every thing appeared fine So most proberly I can expect the misfire and fault code to return. Anyway, the reason for writing is, there are 4 bolts holding the gear and oil pump drive plate on the end of the exhaust cam. These 4 bolts pass through 4 elongated slots in the chain gear into the end of the exhaust cam. Do you know what this adjustment is for, bearing in mind the slot at the opposite end of the exhaust cam sets the timing. Thanks Lionel Boxster 2.5 my97. 5 speed box. RoW. :renntech:
  15. Thank you suberban99 The video was superb, I certainly would not have been able to sort it out without this info. and the other info. on this subject. Thanks again and to Renntech great site. :renntech: I will write again and let you know how I get on. arctic silver my97 2.5 man. gbox. RoW
  16. Hi excellent stuff. I am in the process of doing the same job, I can see the timing marks for the crankshaft and the exhaust cam but I cannot see how to align the inlet cam. I should be grateful for your help with this. Thanks Lionel
  17. I did not notice the timing was out when I first dug into the engine. After I changed the solenoid the same error codes kept coming back. Before changing the solenoid I tested the wires from the solenoid to the DME...and the wires for the camshaft position sensor to the DME. I also swapped the camshaft sensor from right side to left side and still had same error codes on right side. The second time I took it apart I put the engine to TDC #1 and check the timing marks. The chain between the camshafts had skipped 1 tooth. I pulled the camshafts and the Varia Cam unit and the camshaft guides on the bottom of the Varia Cam unit were broken and you could see where chain was getting caught. A new varia cam unit is about $600-800 and the used one I got was $100 (excellent shape) The only way to get them in or out is together. Not very easy when the engine is in car but possible...
  18. Thanks Loren I will check the wiring but the MAF was replaced a few months ago. Thank you again Lionel Hi Loren I have carefully checked the wiring to the Maf sensor and there is continuity in each wire, no shorts and no earths. I have 5volts between term, nos. 4 and3,and 12volts between term. nos. 5 and 3 The resistance between term.1 and 3 is 2700. on the maf itself. The maf was replaced a few months ago in a attempt to resolve this problem. The Bosch number on the new maf was 0 280 217 007 Any help solving this issue would be much appreciated Thanks Lionel
  19. Thanks Loren I will check the wiring but the MAF was replaced a few months ago. Thank you again Lionel

  22. 1998 Boxster 2.5 RoW 5speed manual box. My car has been nothing but trouble since I bought it. It has new CPU DME unit, ignition switch, coil pack set, maff sensor, oxygen sensor over the years but it is still not fixed. I am reluctant to take it back to the main dealer as I have lost confidence in them. I have bought a Durametric test tool and its latest fault codes are listed below. I should be grateful for any observations that would lead to this Boxster becoming a real Porsche. Regards Lionel.

  23. Hi My Boxster does a similar thing and my Durametric tester tells me there is a lock problem drivers side and the interior sensor is not working. So I think 2 beeps means that one of the devices that ensures that the car is ready to be armed is not working i.e. luggage lids. doors, glove box and hood.
