I was drivin home and my oil pressure dropped to 0 for about 2 seconds, then came back to normal. Then about a minute later it did it again, then came right back up. And had not done it previously, and didn't do it again for the rest of the 10 min ride home, should i be worried. tomorrow i will check the oil level, i just got it changed yesterday.

 

I had a friends that did the same thing so we changed the sender on the engine and it has never done it since.

 

Sound like a bad sender. Very common problem with the 2nd gens.

sender......if you have oil in the crankcase, you pretty much will have pressure despite what the guage says....

 

was this when comming to a stop? when My oil pressure drops when going up to a stop sign I know its time to change the oil because it is low.

i just got the oil changed the other day, started happening after i got it changed. I just got the truck and the previous owner used kendal oil and i started with some mobil 1, think this could be the problem, and it only does it when coming to a stop. There is plenty of oil, but the oil looks wierd, kinda greenish, but i never had a diesel so i guess the oil is different

 

Just a thought, when you suddenly change from a regular dino oil to a synthetic, there is the potential to loosen up some sludge. Going to a synthetic can "clean" or break loose old build up in the engine. But, it sounds like you just changed the oil, so it may be a little soon for this to happen, and the "cleaning" or "loosening" of sludge may be a little blown out of proportion, but I believe it can happen.

I agree, more than likely it is the oil sending unit, but just wanted to mention the possibility of the above. Good luck, Kevin

 

My Dad's 98 12v 2500 did the same thing,bought new sender from Cummin's all was fixed good luck!

 

hmmm seems wierd that it was right after i changed my oil...maybe just wierd coincidence, worse have happened to me...how much did the senders run you guys, and is it just located in a bung in the oil pan or what

 

how easy and how expensive is the sending unit for the oil pressure gauge?? my looks like it sticks and something not quite right with gauge.
