Rattling Noise Coming From Engine

[Ronaj]

Hello guys,

I'm new here. I'm currently stationed in Japan and I just bought a 89 skyline GT-R. I drove it around yesterday and it was driving fine. I took it out for a drive today and a rattling sound started coming from the engine while i was driving. Any help would be greatly appreciated, Thank you.

The noise is constant and doesn't change when i rev up or drive around.

doesnt sound to good at all mate. is noise coming from bottom end?

Main bearing mate

I'm not too sure. It sounds like its coming from the top, it started doing it out of nowhere. Me and my buddy were out for a drive and he said that he saw something come loose from the bottom. so i don't know what it could be. the noise seems to be loudest when i'm standing near the top though.

Also the car didn't seem lose any power and still drove fine and was responding fine when i step on the throttle.

yep no good did u just buy it? that sux man..

[Ronaj]

Yes, I bought it 2 days ago, this really does suck. I just want to know what to problem is so I can fix it.

Could be low fluid level in the power steer or bearings in the power steering or alternator. Check PS fluid level. (I assume you've already checked engine oil level).

Nah man they all sound like coming from the top, it's the bottom end. or your cam bearing had spun or could be main bearing. conrods bearing usually click click click or clack clack clack sounds like main I'd be pissed.

cam bearing? what cam bearing?

[Ronaj]

Thanks for the help! I'm going to take a look at it today since I've been busy. Hopefully it's nothing too serious.

Could be wrong here, but if noise it constant, then wouldn't that rule out a main/rod bearing?
