Hey guys, just bought a 1998 259k LX, full service records from Lexus , 40k worth!!! Anyways, I realize despite the clean records, this is still a 20 year old car approaching 300k, but I'd like it to be as perfect as possible.
Trying to figure out this noise coming from the engine bay. I only notice it in park or neutral, could be when in drive there's more engine noise covering it up. It's very weird to describe, almost like some sort of underwater pulsating in a tunnel. Shows up more if I put my ear closer to the radiator. I thought maybe a pump or belt at first, but now thinking the closest thing it sounds to is some sort of exhaust note. Perhaps a leak somewhere in the system? I have no idea.
I posted a OneDrive link of a video below. Probably better audio resolution if you download the file direct to your desktop. You have to listen for it in the background of the video, but it's consistently there throughout the video, gets louder in certain spots. One thing that might give a hint is my gas milage is obscenely poor at the moment. I see people complaining about 12, which is what I expected to get, and would dream about at this point. Feels like I'm closer to 8-10. Almost at halfway down on a tank and I only have 85 miles on it.
Anyways, if you guys have some free time I'd love to know what you think. Thanks!
