well the problem is that my engine is different than Gregs. I got i6 and CPS is harder to get to than on V6 :(

So the WIS tells me to remove the starter but getting to the top bolt is just as hard as to the CPS sensor lol( which according to WIS is like 2 inches away) Is there a special
extension that can reach in there to unscrew the top bolt?

On the other hand i am really tempeted to remove the oil filter housing and end my missery, but dont know yet how hard it is to do that.

Well color me dumb, I should have realized that from your photos. My experience with the WIS is that except for a few rare occasions, following it to the letter will reduce your overall repair time. Good luck!

Bodya, I have not done the CPS on the M104, but just a thought, would removing the motor mount on that side and dropping the engine give you enough clearance to reach it? You'd have to watch wiring and the fan/shroud clearance, but that might work. Just a thought, maybe you can eyeball it and figure out if that would help.

This is one of those times that the task is easier on the modular engine, though that is not always the case. ;)

Good luck.

Hey Greg! after a lot of b**** I finally got to the sensor. Remove the screw holding it but it won't come out.

It's like it's glued to the crankshaft. Did you have this happen with yours?

I didn't, but some have. There is a thread from a 208 owner that was a relative nightmare. :( Oh, and it's just stuck at the surface and perhaps through the hole, the plastic may have deflected and expanded over the years. But it couldn't be stuck to the crank since it doesn't touch it. And if it did you'd have other problems. ;)

Spray it down with Windex, use a stream setting (instead of spray) if you can to penetrate under it. Wait a few minutes and spray it some more, then wait a few more minutes. Then grab it with pliers, try and be gentle and grab the extension of it where the bolt goes through, and twist it back and forth, the goal being to break it loose. Add some more Windex as needed.

Good luck and keep after it!
