  1. If the sensors are going to be changed out, a good penetrating oil should not be an issue. If they are going to be reused, I would heat the sensor bung with a torch before pulling on the wrench. In either case, a very small amount of anti seize on the threads of the sensor before installation is a wise move to avoid future maintenance issues.
  2. While the vehicle may contain VW parts, some of them are running Porsche software, which the VCDS cannot even see. Sometimes these modules drop offline when there is a water short, assuming it is not totally dead, the PIWIS should be able to see and communicate with the module, bringing it back online so it can be calibrated. If the PIWIS cannot communicate, you will need a new module, which will need to be coded to the vehicle, which the PIWIS can also do. Just remember, the 911 and Boxster vehicles also carry VW components, but the VCDS is useless with them.
  3. Yup, reactivate (assuming is it salvageable) and re calibrate the module in question.
  4. Suggest the following as I have learned to never trust pelican instructions: Post Delivery Litronics installation instructions
  5. Are you sure you have the Lits and the control module wired correctly?
  6. Welcome to RennTech Try the Durametric website.
  7. Get LN’s replacement oil pump drive shaft; the factory unit is investment cast junk, LN’s is chrome moly steel. Well worth the twenty some dollar price. I would also get all new hydraulic chain tensioners and their sealing rings, you have no idea the condition of the ones in the replacement engine, and while you have everything locked down to move the IMS Solution over, it is the prefect time to update them.
  8. Welcome to RennTech Most likely you have fried some components, particularly the voltage regulator. These vehicles do not like having polarity reversed. You need to get the vehicle scanned with a Porsche specific tool to see what has happened.
  9. We have a member here that has a 996 with a small block Chevy in it, he summed up the experience by saying he would not do it again...……………...
  10. Which may indicate a problem with the module itself, which will require the use of a PIWIS.
  11. Welcome to RennTech According to Durametric's published model and feature matrix, it should be able to read or clear codes for the Targa roof, but that's about it: Model and feature matrix What are you trying to do?
  12. Fuel in the oil at appreciable levels is usually the result of either leaking injectors or a totally failed sump evacuation system (these engines are designed to run at around 5 inches of water vacuum signal in the sump to aid low tension ring sealing). Without the proper vacuum level in the sump, water and fuel will accumulate over time. I would scan the engine for fuel trims to look for leaking injectors, and test the sump vacuum level with a digital manometer.
  13. The stability management system and DME should not be capable of doing that; only invoking "limp mode". You will not be able to "pick up" a PIWIS, they are only available for lease at $20,000 for the first year. That said, you need to get the car scanned before moving forward; anything else would just be guesses.
  14. P0503 is the code for a bad wheel speed sensor, the rest sounds like you have transmission problems. I would get the vehicle scanned with a Porsche specific scan tool like the PIWIS.
  15. Welcome to RennTech Check Loren's posts earlier in the thread, they contain everything you need.
  16. Two possibles: Oil cooler or cracked cylinder head. Cooler can be removed and pressure tested easily, if it is sound, you have a cracked head.
  17. Seriously doubt a head gasket as they are multi layer steel and acutally stronger than the heads or engine case.
  18. You may have an air pocket in the system from changing the water pump and thermostat.
  19. Welcome to RennTech Common problem, usually the sending unit going goofy. Easy DIY.
  20. More common than you might imagine, Porsche used a strange design cam follower that is very easily susceptible to varnish build up and particulate debris.
  21. Yes, cam followers can bleed down, and can be replaced. Not a small project, however.
  22. Not really, there only so much a digital multimeter can tell you about systems with control modules in them; they cannot see the module programming, state of activity, or read the signals they send out to see if they are correct. You are limited to voltage, continuity, and amperage; which may not answer the question. This is the problem when you have digital "thinking" modules in a electrical control circuit; you need to know what the module is, or isn't thinking, which requires a more sophisticated tool.
