2015 RT with an Oil leak - anyone know the torque on the oil pressure sensor housing screw?

I don't know if there is a torque value on that sensor. It's just a screw that holds the sensor in place. It doen't need to be all that tight. I hope you can seal your leak as you really don't want to purchase this sensor.

Part # 420264166

How bad was the oil leak? I have a 2016 RT with a short ton of miles. What was the part#?

Which part#? Do you mean the part# shown in post #2??

Yes. Normally the part# is a 9-digit number. Also, are we talking about the part that the parts diagram calls an "oil pressure switch"?

I suppose this could be a typical area for confusion. The 1330 SE6 has both, an Oil Pressure SWITCH, and an Oil Pressure SENSOR. (Both were referred to as switches in parts lists until halfway through 2016)

The Oil Pressure Switch is associated with engine oil pressure, and is located approximately below the oil filter, pointing to the rear. It’s the thing that lights the Low Oil Pressure light on the cluster. It’s literally a switch, either on or off. Upon double checking, I cannot see an O-ring or housing associated with it. Just a harness connector. The switch has threads and screws in on its own accord. There are Loctite and torque requirements

The Oil Pressure Sensor - AKA Clutch Pressure Sensor/Clutch Oil Pressure Sensor - is associated with the clutch and is located approximately below the HCM oil filter. It does have an O-ring and a housing associated with it. The housing is not removed in order to change the sensor. The sensor screws into the housing. The housing itself is screwed onto the clutch cover with two screws and a gasket. Similar to an O-ring. It can be replaced and the old sensor re-used. Sensor threads and housing screws (2) threads also have Loctite and torque requirements.

So, which one you guys are talking about should probably be clarified. Unfortunately, I can’t help with Ron’s part number. It’s not correct, and not a variation of the correct part numbers. Sorry. PS - since been corrected.

Thank you for clairifying this for me. Hope mine don't fail as the sensor is very expensive.

OK, my bad on this one. I was referencing the Cam Position Sensor, which is the source of a much more common leak issue. The part # I gave in post # 2 was not for the Oil Pressure Sensor located low on the engine. I have corrected that error.

Clearly, you don't want this sensor to go bad. The price on this is in the stratosphere! I really don't know how BRP can justify this kind of pricing. There just can't be that much money in these.

Part # 420264166

This is the current superseded number.

I apologize for the confusion.

Just a thought. Have you changed your HCM filter lately and have you checked that the bolts were torqued correctly?

As mentioned by BajaRon, my Cam Position Sensor failed and I got a limp home warning. The plug when I removed it was full of oil.

Have not changed HCM filter yet and did check the torque on bolts. Still could be the oil pressure light switch, will check that tomorrow.

Yeah, that’s quite a change in location focus from the clutch oil pressure sensor (Low - the one with the housing), to the engine oil pressure light switch; a higher point on the engine. And realizing we don’t know what you’re seeing, how long that you’ve owned this thing, how heavy it’s leaking, or how long it’s been leaking. You’ve got this potential item:


Or maybe your oil filter cap is not tight or the o-ring is leaking, or cam sensor, as mentioned above. Even higher points. Or just residual spillage from an oil filter change. Oil leaks run downhill. Not quite sure? I would suggest you get a can of Gunk Degreaser, hose down the area until it’s clean enough to eat off of, and then make a systematic observation to identify the source.

You can get a UV dye to add to the oil. It fluoresces under a UV flashlight, and makes it easy to spot the source of an oil leak.
Still helpful to clean it up first.

Harbor Freight may have it... Dye

Best I can tell after letting it run for 20min. looks like the filter cap, need to do an oil change anyway. Never had filter cap leak before. Time will tell. Thanks

Have you been changing the o-ring on the cap or reusing it?
