whining engine noise (1FZ-FE DOHC Engine (1 Viewer)

[Jack Michael]

Gentlemen:

I am currently having this engine noise problem with my subject SUV and was wondering if anyone can help? The mechanics of our local Toyota repair shop have given up in solving the problem - it seems they are not ready to open-up the engine. after a week of trying to solve / locate the problem.

Actually, before this noise really came about, a leak from the vehicles power steering pump was noticed. The said pump was then removed and some o-rings / other parts were replaced. While I did think the leaking problem had been solve, a certain noise from the engine came about after a week of using the vehicle. Anyway, it was determine that the power steering pump was not re-installed properly and had caused the body of power steering pump to crack. In the absence of a new pump, the cracked pump was temporarily welded together and re-installed. While we saw that the repaired / welded power steering pump was working well, the whining noise has not dissappeard. While the mechanics think I should just live with the new engine noise, I honestly believe some internal parts may have been affected when the power steering pump was not installed properly.

For your added info, the noise is not coming from the repaired power steering (ps) pump as we did try starting the engine after removing the repaired ps pump. The whining sound was still there.

Thank you very much and hope to get some help from your group regarding my concern.

Seems like I've heard two variations on this noise. One very competent member here (can't recall who) put a new factory pump on and had a whine until the new gear on the pump shaft wore/meshed with the engine's direct drive that drives the pump. Then it went away.

Someone else had an install issue like yours that damaged the engine's direct drive and a new pump didn't solve it because the damage caused a lifelong whine. Your pump clearly was improperly installed/assembled. Dunno which result you'll have, but some input for you. I believe in the first case above he also put the old one on as an experiment and got whine noise despite the gears having worn in together, because different gears were now meshing.

Hi Jack, trying my luck here but did you resolve your issue and find out what the problem was? I am in the same boat as you.
