Oil Pressure Switch

[mgbrv8]

I heard some horror stories about removing the Oil pressure switch on our motors. Some people would lift the motors up with a hoist others would remove the motor mounts and jack up one side of the motor even read one story or a person removed the exhaust header on that side. Mine was leaking so I decided to take a stab at it. I started from the passenger-side trying to get to it but after a while my hands started cramping from trying to fit in the tight spot at a odd angle. So I step back and took a long look at the situation. I Figured out if you lay a series of blankets over the motor from the drivers wheel over the engine to protect everything and if you lay on top of the engine from the driver side you can reach your left hand in very easily. I also disconnected the oil cooler lines to ease access and plug them with plugs I had in my toolbox, this gives you a few more inches of freedom with the ratchet but it isn't absolutely necessary. Its also nice because with your left hand is in there working you could look right down at the switch through the exposed section. I also dissected the bad switch to see what failed.

Well, I had a leak on the passenger side for awhile bu it wasn?t too bad. Recently, amount of leakage got to a point where oil was collecting on the cradle and drip on to the garage floor.
Ordered a replacement sensor from Jerry?s gasket and decided to replace it yesterday. To be sure I had necessary tools and for metal assurance, drove to Phils?s (Jagdpanzer) house.
Looking at it, not much but looked like I could stick my hand in there and get it out without drastic removal of oats. Impatient as I am, I started attacking it before the motor had time to cool. Holding 27mm sensor removal socket, 3/8? drive to 1/4? adapter and a 1/4? drive ratchet (wish I had swivel head), stuck my hand in there. After fiddling for awhile, 4 burned spots on my hand and skin peeling off, got the piece out.
Getting the new piece started was a breeze with Dr. Phil?s impromptu wooden extension mated to sensor connector head. Bolting it in was much easier since I am pushing and more room in that direction.
Phil did a postmortem and interesting the failure identical to mgbrv8?s finding.
I tried to upload the image but somehow I can?t convert to jpg.

Figured it out.

Thank you Z06scentair I just want to help our and future members and owners

I forgot one helpful hint. To keep from straining my wrist while turning the ratchet and trying to hold up the ratchet and socket combination with my fingertips I made a 10 inch length of stainless steel wire with eyelets on each end. I put one eyelet in between the socket and the ratchet head and protruded the other end up through the view port of the oil pressure switch this allowed me to not only hold up the socket against its weight but also to help place the socket on the switch initially. Another point the finer the ratchet the better because you don't have much swing in there. The job in total was about 35min.

Seems they could have integrated the OP light into the OP guage...

Get Cliff to link it in 'Solutions'...

Could have.... but better to have redundant sensors on critical functions. It's helped more than on ZR-1 driver when one has failed, usually the gauge sensor. Personally, I prefer a mechanical oil pressure gauge added to the pressure switch.
