no oil pressure

[gobcumminstruck]

i was driving home last night, from work and oil gauge went to zero and light came on. i heard a noise and pull over to side off road. and the noise came from rt side of truck toke pipe of turbo and it was it. i limp it about 5 miles back to work.i put an mechanical gauge on oil filter houseing and find i had no oil pressure. its an early 1991 w250 non intercooled engine. and the truck has close to 600,000 miles on it i dont know for sure the excet miles, cause the odometer has work since i bought the truck and dont know how long it hasn't work. what could be my problem?

If the turbo failed it may have dumped all the oil out of the engine. Either thru the tailpipe or it went thru and burned it.

i check the oil stick and it has the right amount. i check it wend i got to work and let it sit and check againt it had more in it, meaning it was pass the full mark and it was black to, no fun color oil,and coolant full to. no coolant loss and coolant not different color.

I am suprised you made it 5 miles with no oil pressure. Are you sure you used a working gauge? You could pull a valve cover and fire it up and see if the oil flies or not.

i m to. the gauge works its an set i very carefull with thst i buoght to chek engine and or transmission pressures with. its an mac brad. and if say the oil by pass the oil filter and turbo then y the truck gague not workin cause it was workin before this

[Remps]

Well, I am stumped lol. I know my oil pressure gauge quit working on my D250 a few years ago. Shut it off and pulled over and pulled a valve cover and started it, and oil went flying everywhere, so it was just my gauge.

I have an engine that did that and the kdp took out the oil pump idler. I think the first place to go is to that front cover and remove it.....

[gobcumminstruck]

I know the gague senor works cause I replace it an year ago so I guess it works stall I guess. And wend I got the truck 2 years ago I made an plate to cover pin and red lock tight the bolt. I plan to take cover off to check it and the oil pump. I just see what ya's thoughs on it and see if this happen to someone to. I also find oil presuer regulater and check it.

[gobcumminstruck]

does anyone know how to get the oil pressure regulator out? i got spring out put cant get the pison out or whatever u call the thingy under the spring. i stall goin take ft cover off as soon i can get it from work to home.
and check oil pump.

[ellis93]

Well what was the problem?

[gobcumminstruck]

i dont know havent got an chane besides i been thinking of junking it case i need an vechinl to drove t work and dont hav the money to fix i think it be oil pump and need an new oil cooler cover cause the plunger for oil pressuer regaltoer is suck in it an cant get it out. and i need an turbo thats y i ask about them

[ellis93]

Junk it? Damn that sucks

I bought a used oil pump off of Ebay for 35$,the rebuild for the turbo should be less than 150$ (if you need a turbin shaft I can hook you up) as far as the bypass if its stuck in....who cares,cap that baby back off and forget about it (it's stuck closed right? )

[gobcumminstruck]

ok. i not sure were it stuck at i just dont hav oil pressuer anywere in engine i dont hav much money to fix right now so it either sit or junk so i hav/get sometging to drve. ya it does suck.

[gobcumminstruck]

well its for sure it needs an turbo and oil pressure regulator. and maybe and cooler cover cause the reglator suck in it and i need money and somwthing to drive and onlyu way i can is sell truck as whole or juck it. thanks for the help

Change turbo or repair turbo. By doing so your problem may be fixed
