check gauges ligth comes on when idle


Asked by Sep 28, 2015 at 01:13 AM about the 2002 Dodge Ram 1500

Question type: Maintenance & Repair

I got a problem with my 02 dodge ram 5.9 check gauges light comes on and OP drops to 0, this happens when the temp gauge is at normal and RPM are at 650 if Rpm are at 700 or temp gauge is a little bit below normal it won't do it, I have replaced the oil pump, the strainer inside the engine and the OP sensor and it still does the same, I want to note that when I drop the oil pan it was like mud inside it looks like they had drop the pan before and when they put it back they overloaded the oil pan gasket with silicone because even the oil strainer was almost clogged with silicone I did clean the oil pan and I could pick up with my two fingers the sludge out of it, any suggestions or ideas of what I should do next, will be very well appreciated, some one told me to drain the oil and add a gallon of diesel into the engine to flush it, should I do that? thank you in advance for you advise.

i didn't even read this man do not drive that truck anymore anymore unless you want to spend a bearing. Pull the pan and clear out all the the pick up to the oil pump stuff clean it all out get all the freaking gunk out there and clean the tubes the pick up tube everything then change the oil and try it

oh sorry I just now read that LOL. Throw some seafoam In it. you did the right stuff to me and my buddies just three weeks ago freaking locked up tight from the same thing Brett had to put a brand-new motor in it


Thank you, Joshua, I saw on a forum a comment of a guy saying that draining out the oil and adding a gallon of diesel and run the engine for about 15 minutes then drain the diesel out then replace the oil and filter will work, I am thinking about doing it, do you know anything about doing that?
