is it best to get to it from the top or bottom of the engine ? and do i need the special socket or can i use a wrench or channel locks? ??

[scottykilmer]

@brandon1997bmx bottom, but get the socket or you'll break things.

Where would this be located on a 1996 plymouth voyager 2.4L ?

@brandon1997bmx on the side of the engine under the ac compressor, hard to get to

Hi Scotty. I have an 82 chevy pick up with a 350 and I installed a oil pressure gauge on it. When I start it, it marks that it has 50 to 60 psi and after I run it for a while and come to a stop it marks 10 to 0 psi. Can it be that I have a bad gauge or is it normal when the oil heats up and the viscosity goes down. And I already replaced the oil pump. And also, can it be that the cam has some thing to do with it. Its a small cam.

@XralphiX that's not normal, IF that gauge is working correctly, you have internal engine wear causing that, anythying from a worn pump to worn engine bearings creating too much space thus lowering oil pressure

@XralphiX it could be your oil pressure switch.

@scottykilmer Thanks Scotty.

@kurtnin42manson just fill it to the top of the mark, regardless of what the book says, all engines retain a certain amount inside when changing

@kurtnin42manson also, when I took it to Ford for the free oil change I got, i noticed on the paperwork, it said they only added 5 qts also. I know that I should also go by the manual, but what if it's just too much?
