  1. Schnell, one thing that has not been talked about on your problem is the mechanical timing between intake and exhaust cam. A common problem that is easy for the chain to slip over a tooth when trying to assemble the cams with chain and tensioner especially if you don't have the engine vertical. There are two gold colored links and two dots on the gears to time this(of course you already know this, I think this is a new build?). You can check this quickly by putting the engine in TDC same as setting the cam timing for the exhaust cam. then remover the cam plug above the bank 1 oil pump, look at the tang for the cam sensor, it should be pointing directly to 3 o'clock away from the head. If it's anything other than 3 o'clock the cams will have to be removed and retime intake to exhaust cam timing. I have seen this a few times and it will cause code p1341 and also will not allow cam actuator to advance/retard timing because it is too far out of spec.(14.9). There are 24 teeth on the gear that means 1 tooth off will give you 15 degrees off ie 14.9

  2. To get the center bolt the best option would be to buy the Pelican Parts kit for $165. It comes with an improved center bolt and also the needed spacers to install a single-row bearing in place of the dual-row. Since the dual-row 23.8mm wide bearing is not available to the consumer (only Porsche can get that one), I'm assuming you are either using a 20mm wide dual-row , or you are using the 14mm wide single-row. If your preferred bearing is a 14mm single-row , the spacers from the Pelican kit will be what's necessary. If your preferred bearing is the 20mm wide dual-row, you will still have to source a 3.8mm spacer.You didn't say what bearing you were using, but IMHO I would not be using any type ball bearing , a roller bearing only would be used, or the Ultimate IMS Solution.

  3. Codes p1130 and p1128 are codes indicating the mixture adjustment has reached its adjustment limit. It could be the max limit lean or the max limit rich. The  best way to tell is to look at the RKAT values before erasing any codes or resetting values , if the RKAT is at -.38 the system is at the lean limit indicating a rich condition( usually a faulty MAF sensor) , if the RKAT is +.38 the system is at rich limit indicating a lean condition(usually from an air/vacuum leak). Using this method will help keep from false diagnosis.

  4. If I were you , I would spend a little time searching through TSB's . I seem to remember about 10 years ago a TSB about the ground wire connections on top of the engine. There is a ground for each bank, if the ground is faulty it will cause all sorts of crazy codes and intermittent problems. Its been quite a few years since I have fixed one of those , but I have seen a dozen of so.

  5. Its a good idea to check the cable mounts like previously mentioned ,I have seen a lot of them tie-strapped due to retaining clips broken . Also adjustment , if the factory alignment tool will not fit the B&M just align both cables perfectly even . As far as the cable function , ONE cable is for selecting one of the 4 shift gates,(R-) (1-2) (3-4) (5-6), the OTHER cable is for selecting up(R-1-3-5) or back(2-4-6). So when doing the 2-3 shift the function is, cable 2 shifts half way up to neutral, then cable one switches gates from (1-2) to (3-4), then cable 2 shifts the rest of the way up.

  6. Had a customer once who had a sulfur type/ rotten egg smell coming from the exhaust pipe off his 997 and some times a light white smoke from the drivers side exhaust tip. Turned out a chipmunk (rodent) had been storing dry dog food in his drivers side muffler !!! Dumped out about 1/2 pound of burnt dry dog food from it , strange thing is he said he didn't even own a dog .. and far as he knew his neighbors didn't either!! lol

  7. Disconnecting the solenoid does cause a DTC (although does not turn on the CEL) the DTC is there next time you run the scan . Although some solenoids disconnected, like the one on the air cleaner ,for Helmholtz resonator will set a background DTC and ALSO disable sport button . Switching to a resistance of equal value WILL satisfy the DME and not set DTC if the switch can be done instantaneous , with no drop or rise in resistance . Give it a try , it just may work!!

  8. I think if you defeat the DME in this manor you will set a DTC fault (although the check engine light will not illuminate) . The DME looks to the solenoid for resistance checks on start up to see if any wiring , solenoid , resistance failures are in the circuit. The only ways to have the PSE on all the time without setting DTC's are (1) to disconnect the vacuum lines ,(leaving the electrical" as is") or (2)to add another control system like wireless remote to control the PSE . I have a wireless remote that I use for Sound Symposer Retrofit kit for 996 997.1 that will work for PSE also. I'll attach a picture and can visit my website at www.bansheestethoscope.com for more pictures and info . Best regards
