Unhappy I am not sure what happened but it doesn't sound good

While driving today on the highway, approx 15 minutes into my trip,
I started to feel a sort of knocking when I accelerated. I was
going about 55-60 mph. I would let off the gas and it would
decrease to a very low level or maybe even stopped. I tried to
accelerate again and it began to knock again. Went on for approx 5
minutes when my engine light came on. I travel approx 2 miles to a
gas station and checked my oil and belts. No major problem, added
about 1/2 to 2/3 a quart of oil and the dip stick read completely
full. I drove maybe five miles and this continued to my house where
it sits. Any diagnosis? Possibly oil pressure problem or even
worse a bearing problem. It is a 1997 limited edition with 170,000
miles, 4 x 4, V6 Engine. Any suggestions or feedback appreciated. Im new
to the board so hello all from eastern NC!

Limited edition what? What type of vehicle? Engine size?

I agree with Darrell. Sounds like internal engine failure, rebuild time .

A shop can check the oil pressure with a gauge and advise you if there are internal problems.

Unhappy Sounds like bad news

Its a toyota 4 runner 1997 limited edition 4X4. How can this problem happen. Old age? Improper treatment? I have only had this truck for about 3 mos

Mileage is up there at 170k. It could have been abused before you got it. It may have had poor maintenance.

Things also just wear out, which is a possibility at this mileage. Chances are it was happening for a while (losing oil, leaking, etc).

Was most likely bad from the beginning. I have seen a guy with a veh like that, knocking and no oil pressure, remove pan and without checking anything, just install a set of rod bearings or mains and then use a trailer to haul to the auction. They dont run a long time after that kind of hoodinie treatment. But some guys have no concience. Once they start knocking, the end is near.

had someone look at it

and they said they thought it was a CPU problem. The oil pressure and levels were fine as well as the engine temp. How does this sound?

Doubt it. Oil pressure is a mechanical issue. Only way that's possible if if the engine was flooding with fuel due to a rich mixture commanded from the ECM. In such case the truck would run terrible!

It's either been neglected or the motor is simply worn out. Period.
