Engine making weird noise - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys, I just picked up a 1993 240sx and its making a weird noise in the engine bay. It has a faint knocking coming from it sometimes. While its knocking it sometimes sounds like there are squirrels fighting in the engine. I don't know how to explain it any better than squirrels fighting

Does anyone know what it might be? I am dreading its a spun bearing. Maybe a throw out bearing? Please help!

PS....WOOT 1st post! LOL

You might try making a video of what happens so people can see and hear... fighting squirrels lol.. How is the performance of the car?

No loss of performance.

What the hell was that screeching sound from 0:27-0:30 in the video? Some starwars jedi lightsaber engagement? Haha nah, but a knock should be louder and more noticeable.

WTF, that made me jump lol. If you think it's the TOB, does the sound change when engaging the clutch?

when I got my 240, it had a actual desert squirrel living under the hood!

That was me busting out my light saber! LOL it was my phone. When I pressed in on the clutch it didn't change.

Its hard to tell in the vid, but I know the mechanical clutch fans make that noise like crazy when they get worn out

I don't have a clutch fan anymore. Have 2 slim electric fans. Tomorrow I'll get my HD camera and get a better video.
