How Do I Get The Fuel Rail and Injectors Back Into The Air Intake?

[beechner]

This question is related to my efforts to fix an intermittent coolant temp gauge, oil level and oil temperature reading failure on a 2007 Boxster with the 2.7L engine and a five speed. My thought has been that there was a wiring issue perhaps related to our very active local chipmunk population thinking the top of the engine was a lovely place to stay in the winter when the car was not being driven. And since the wiring for both the coolant temperature and the oil level/temperature unit is on the top of the engine on the 4 -6 cylinder side I thought I would have a look. Following the instructions in the service manual, I removed things down to the 4 - 6 fuel rail with injectors and then came to the realization that the front bolt on the intake tubes sits under the AC compressor and I had no way to get to it without removing more stuff than I wanted to. I could already see that the wiring looked good although the top of the engine was covered in chewed up acorn pieces. I vacuumed those out and then wanted to reinstall the injectors but can't get enough leverage to get them back in nor can I pull out the fuel rail/injectors to put on new o-rings. What's the trick here to getting this back together? I'm incredibly frustrated at this point since I've never had any difficulty on other cars doing the equivalent with fuel rails and injectors where there was actually space to work.

Try a little lube on the o-rings. Dielectric grease should work.

Also on the 996 at least you can safely drop the engine a few inches to provide additional working room. Not sure if this is true about the 986/987.

Thanks for the suggestion. I do intend to lubricate the o-rings once I can actually reach them. As it stands at this point I can't even reach the o-ring on two out of three to do that. I had thought about resorting to dropping the engine a bit and I'm thinking it's possible but I'm hoping that's a last resort. The main thing in my way at this point is the air box so I'm going to try to get that out to give more room but I have to remove the roll pin from the last attachment to the body and then even with it free I'm not sure there's room to pull it out. Anyway, I'm going to give that a go along wiht the o-ring lubrication and see what happens.

I'm wondering if you found the answer to the intermittent coolant gauge and oil level sensor? The same problem has just started to occur on my 2005 Boxster 987 S
