Hybrid 4runner/pick up toyota 4x4 22r engine, making strange RRR..RRR noise

[whoFNcares83]

had a similar sound from 20r. was freakin out so i called a friend's hotshit mechanic. he arrives, starts it and in 10 seconds he blurts out alternator. I instantly thought he was a Jcat or a moron, but he reaches in while the motor is running and with two hands grips around the alternator and the noise stoped. I had thought timing initially as well. He explained that sometimes they begin to come apart from the inside out and make crazy noises. Water like oil is no good, water in the oil or thin

Did u ever figure out what the problem was?? This is happening to my truck right now an it's extrnrly frustrating

after changing oil, distributor cap, rotor, wires, fuel filters, spark plugs, agency oil filter, fuel pump, the truck runs very very good, but that strange sound is still there, man,,,,it is not the chain,..everything in there its new..too..but i am thinking about the steering pump..i need to flush it and we will see..the sound seems to come from there, i am pretty sure that the steering pump is my problem...if not well i will keep digging it is fun...

I am not hearing anything that does not sound like normal 22R sounds.

How long have you owned this truck?

[javiererl517]

i have owned this truck for about 10 years...the engine is fine..but if you listen carefully there is an rrr rrr sound, the timing chain is new, so ,i think the sound is coming from the steering pump, i am going to flush the system and drop in a good oil and we will see..i think that's the problem,,my oil looks like water.
