LOW OIL PRESSURE?!?

jsklenar · January 7, 2014

Your problem is the screen under the oil pressure switch. you need to remove the sensor again and take the screen out from under it. you can clean the screen but your best bet is to just replace it. I see this a lot and just replace the screens with the new sensors.

Your problem is the screen under the oil pressure sensor is clogged. you need to remove the sensor again, then remove the screen. you can clean it but you are better off getting a new one.

My 05 had the gauge cluster problem. Some mornings my tranny temp would be at 250 the moment I turned the key. I also had oil pressure between 0 and 180 PSI, which was unsettling. I sent the cluster out for a rebuild, and it set me back about $125 including shipping. Works great now. Easy to replace. Drove the truck with just a Garmin while it was out for repair.

We've seen the screen issue a lot at work

Have been trying to search for this Topic Title. Can't find much info. Was wanting some help in this area.

2006 2500HD 6.0 Low Pressure Oil 162,000 Miles. 0 oil pressure on gage in truck, engine making lots of noise, Sounds almost like a pulley/bearing going out. I'm going to test pressure in sensor spot today with mechanical gage. Thinking its the Oil Pump. Was wondering if someone would point me in the right direction as to how to change oil pump by steps. With maybe some diagrams.

The Chilton manual has a decent write up on this, just be prepared, you need to raise the motor a bit to be able to get the oil pan out with the motor still in the car. While you're down there if you can get to the rear main seal you may as well change that. (Might as well put in a new oil pan too! they are cheap, and do rust) This is a long and tedious job.

That said, engine making a lot of noise, probably is a bearing. You can change them while you have the pan out of course, but that MIGHT not solve the problem, if its a cam bearing then you need to take the top of the motor apart as well and pull the cam. May as well pull and rebuild the motor while you are at it, it will be a shitload easier to do the work.

Your oil pump may well be perfectly fine, oil needs friction to make pressure. If the bearings are shot even the best oil pump won't solve your problems.

Wow that's a lot of work... lol but thank you for the reply. A friend is coming over to look at it and help me do a oil pressure test to check that first. Will give you and update on it after that thanks
