Hello,
New to this Forum but am also on a couple of others. This looks like a good site as well.
I have a 1991 944S2 Cabriolet. My question is on installing a new Hall Sensor. Those little things are expensive!
It looks like I may have to take the valve cover off just to get one of the bolts out to replace the sensor. Is that really the case? If it is, how difficult is it to take the valve cover off? Do I need to disconnect the fuel lines in back? Do I need a new gasket? And last but now least is there a right up on this process so I know what to look out for.
Thanks!

 

Nope, no need to remove the valve cover, but it is tight. A 5mm allen is what you need to remove the hallsensor (2 screws). Unclip and reinstall.

If you want to remove the valve cover, then you needto undo the 2 fuel line connections and make sure you wake up the valve cover bolts with a punch and hammer to knock the corrosion loose. They have a tendancy to break otherwise. You will want to put on a new valve cover gasket and the 4 spark plug gaskets as well if you go this route.

 

Thanks! I'll give it another shot. I do want to pull the cover at some point to clean it up. Maybe powder coat it. Thanks again.
