V8david Posted July 3, 2008 Share Posted July 3, 2008 Hi again everyone. Since putting the motor back together (3.5 V8 Efi), the only oil leak I have (so far!) is from around or through the oil pressure switch on the oil pump cover. Can't tell if it's coming through the switch itself or the sealing washer so I've got a new switch, with washer. I'm changing the oil very soon so I just need to know if I can change the switch over with the pump in situ? Will removing the switch mean that the oil pump will need re-priming. Ideally I want to empty the oil, swap the switches, put in new oil, job done! No more leaks! For now! Cheers David Quote Link to comment Share on other sites More sharing options...
Guest noggy Posted July 3, 2008 Share Posted July 3, 2008 yes, just a case of draining the oil and swapping the switch over, or you could not drain the oil, and do it really fast and then just top the engine up... it does get a little messy but ive done it Quote Link to comment Share on other sites More sharing options...

Did think about the quick swap but as I'm draining the oil anyway I'll be ok! Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted July 3, 2008 Share Posted July 3, 2008 I've done it in-situ without draining the oil, just be a bit quick. To find the leak, spray it with brake or carb cleaner to get it totally clean & dry, then you an see where any new leaks are coming from.

When you undo the old switch a very small amount of oil will out of the oil gallery that it sits in...............here ne are talking an eggcup full. Often the actual switch body leaks .................... the quality is poor, regardless of supplier.......... I usually get through at least one per year.

I can just swap them as and when... Annoying thing is there are no other leaks now, just this tiny bit through the switch. Better touch a big bit of wood now! Probably go outside to find the sump contents on the drive Quote Link to comment Share on other sites More sharing options...
