Hi All, a question or two for you... First, I notice at seemingly random times (wether engine is hot or cold), the oil (pressure, level?) light in the instrument panel flashes for a few seconds before going out. I had thought this was a pressure light since immediately after performing it's first oil change on my clock, the light flashed for a few seconds leading me to believe the system was building pressure. Is this right? And, is the random occurence anything to worry about? Also, I'm wanting to change the front and rear diff fluid to work on getting all fluids switched to synthetic. I can see the drain plugs on the diffs, I'm assuming it's good to make sure the fill plug comes out before draining them - maybe using some penetrating oil if it's really tight. I've never changed diff fluid in a 4x4 - any gotchas or different procedures to be aware of? I'm a fan of Mobil 1 Products and was going to use thier gear oil - what's the best weight for these things? Regards, - Ryan | ||

Ryan, what yr. model? In regards to the gear oil 90 weight is the best weight. Just take off the fill plug first then the drain plug if difficult to remove then you could SLOWLY loosen it with a braker bar. When speaking of changing rear fluid there is not much difference between 4x4 or non 4x4. Trey & Melissa Burns 1989 white Range Rover "Redneck Rover" | ||

Does the oil light just flash for approx. 20-30 seconds on start up (assuming its an RRC)? If so, that's your low oil level sensor. Try cleaning the connection between the sensor and the harness. It's down right next to the pan. I have to clean mine up every spring as the salt gets into the connection and corrodes the contacts causing the sensor to indicate a low oil level. | ||

Trey, sorry - it is a '93 County LWB. And thanks for the tips. Just about as complicated as I thought - not too bad a all. 90 weight as well - that's great. The Rangie takes all the same wieghts of fluids as does the Benz, so I've got plenty lying around. Is there a fill mark to know how much to put in? And yes Bill, it flashes but not even for that long. I've repeatedly checked the level and I'm right at the 'full' mark, so I know I'm good. I'll get under the beast and look for that sensor - remember which side of the pan it's on? Regards, Ryan Seattle '93 County LWB '95 E420 | ||

i run 80/140 red line synthetic in the diffs in both my 95 disco and my 93 lwb...i carry heavy loads often down to mexico and do lots of wheeling...not so much in the rover.. if you do wheel or carry loads often put 80/140 in | ||

Sensor is on the passenger side of the oil pan, can't miss it, mine randomly flashes once in a while too, I wouldn't worry about it if you check you oil levels often. Fill diffs till they overflow out the fill hole then plug it up. | ||

1/2 inch socket fits in perfectly to remove differential plugs...also make sure to drive your truck a bit to warm up the fluid for ease of draining...also the night before you do the change over spray the plugs with pb blaster for ease of removal | ||

Yep, oil level sensor is on the passenger side of the engine (i.e. right side of the engine). Sensor-to-connector wires are maybe 4-5 inches long so the connector that needs cleaned up will end up being just about at the same "height" as the pan-to-block joint. | ||

I cut my oil level sensor wires off so I would not have to jack with the oil light flickering on and off. If the level sensor does not fix it, you should also check your oil pressure switch. Giggle the wires while someone looks to see if the light flickers. Trey & Melissa Burns 1989 white Range Rover "Redneck Rover" |
