3.6 Pentastar oil pressure sender woes.....
I have done many of them. The van is only one you can get it out that way if you lucky enough to have the fitting in the adaptor not spin on you. It's not bad to remove the intake on them anyway. Now the 3.6 in the Grand Cherokee sucks to get out. I have replaced many that the oil change places crack cranking the oil filter cap down.
