  1. Yeah the compromise of a direct injection engine is they don't have the washing effect from fuel being injected upstream.
  2. The fuel line is a flare fitting. It can be separated from the manifold and aligned into the flare first before the manifold is lined back up. I understand your frustration. The first time around is a royal PITA. If you had to do it again, I guarantee it would go much quicker. Sent from my iPhone using Tapatalk
  3. The T25 screw is threads up as in you’re unscrewing it down towards the ground. Sent from my iPhone using Tapatalk
  4. Mine is a 2009 3.6L V6. The black horizontal tube you're talking about sounds like the step where I said to remove the water hose bracket with a T25 torx bit. The bracket is a keyhole slot so once you remove the T25 screw you can slide the bracket towards the front of the car and release it. Once that is free the black tube moves out of the way giving you access to those triple square bolts.
  5. You can kind of tilt the intake manifold towards the back firewall and free the fuel line after you’ve pivoted it up. It does take a little bit of wiggling/working it. It’s a flare fitting which looks like a cone that fits inside another cone. The fuel line flexes around a little which provides the resilience you need to pop it out. You can pull the line down a little with your hand to free the cone from the upper fitting. Sent from my iPhone using Tapatalk
  6. If everything is unbolted, you should be able to pull the intake manifold up from the passenger side and pivot it up from the drivers side. Once its up a few inches you have a little bit of space to wiggle it free from the upper fuel rail nut.
  7. Thanks, I get it. The first time I removed my intake manifold was for the same reason, failed PCV valve. I got a replacement diaphragm membrane for $20 and spent the whole night removing the intake manifold because there was no tutorial to follow. It was frustrating. I was slowly working my way around the engine trying to find all the mounting bolts and wiggling the intake manifold until it felt free. When I put it all back together I had a slow gas leak due to the fuel injector seals. Coming from the BMW world where there is a tutorial for everything, I decided to document the process this

  10. Interesting. When I did the cooling system refresh I replaced the water pump (front of engine) and thermostat (side of engine) so that confuses the hell out of me why they would call that a water pump thermostat housing if neither of those components are back there. Was it a fairly straight forward job? Doesn't look like I would have to remove much to get to it. I may take some pictures and make a DIY for the job.
  11. Thanks for the PN! Doesn't look very expensive, my local dealership has it for $26 and the o-ring is less than $2. I think the thermostat is on the back of the 3.2 V6 but for the 3.6 V6 the thermostat is on the side of the engine (driver side). I know this because I replaced it during my cooling system refresh at 90k miles. However, there does seem to be a housing for something back there, I'm just not sure what it is..
  12. The common coolant pipe issue seems to only affect the V8 Cayenne's. I'm wondering if my coolant leak is a common problem too. I've been losing coolant on my 3.6 V6 Cayenne at a fairly slow rate compared to the other more common issue. I'm having to top it off about once every month or two. Last weekend I was changing the oil and started investigating the leak. It looks to be coming from a black plastic coolant hose fitting on the back of the engine, passenger side. Has anyone seen this problem before? I'm wondering if there is just a bad o-ring behind that fitting or if the whole
  13. Follow up post for anyone who has this problem in the future. I replaced the thermostat with a new one and fixed the issue. I confirmed it was a slow opening thermostat when I removed the old one and put it in a pot of boiling water with the new thermostat. The new thermostat opened as expected while the faulty one did not open until later. Both thermostats were bought from the Porsche dealership. Side note, the replacing of the thermostat on the 3.6L V6 is a PITA. It is in a hard to reach area with hoses and wire harnesses running in front of it guaranteeing that you will walk awa
  14. I recently replaced the thermostat on my '09 Cayenne 3.6L V6 with a genuine Porsche thermostat along with water pump, belt, etc. Ever since I replaced it I've noticed that on the first start of the day, when the engine is bone cold, the water temp creeps past 1/2 mark and to the 3/4 mark sometimes before it settles back to 1/2 mark. Once it settles at the 1/2 mark it stays rock solid, no issues whatsoever in 100F ambient days in stop and go traffic. Did I get a bad thermostat? It feels like a slow opening thermostat to me. Sometimes I think its in my head and maybe it behaved this
