4U2NV

Alright, I'm getting a weird sound from the engine which becomes noticeable after 3K rpms... It may make the sound below 3K, but it's not nearly as audible... It sounds kinda like a baseball card in bicycle spokes, and goes away promptly when the gas is released... The car doesn't seem to perform any differently, and drives like normal, but just that damn noise...

Axles are good, drivers side was replaced about two weeks ago... I've checked all the bolts on the manifold flange for my header, so I don't think it's an exhaust leak... I do get a brief squeal/whir at startup, could it be something with the alternator pulley going bad...? I'm going to try a valve adjustment tomorrow, and if that doesn't work I planned on taking off both the p/s and a/c belts to see if that eliminates the problem...

If neone has experienced symptoms like this and figured out the problem, your remedies are appreciated... I'm open to suggestions... TIA...

Night bump...

2 things that I think it could be:

1. valve lash too loose, need a valve adjustment

2. loose flywheel bolts. I had this problem before and it sounded like what you said. Eventually they all loosened out and I had to pull the tranny.


So.. I'd try a valve adjustment (can't hurt) and if it's still there it's probably more serious.

had the same problem. at lower rpms you could barely hear it and once i got into the 3.5-4k range you would start to hear the noise again like a wood pecker. needlessto say on my way back from the dyno i started to hear this noise and about 20 mins away from the dyno it got louder and louder until my oil light came on and i knew i spun some bearings.

i would do a valve adj and if it doesnt go away drain your oil with 2 paint strainers you can get from local parts stores and see if you have any metal in your oil and if so it may be a main or rod getting ready to spun, how many miles do you have on it

ive had this problem too. does it sound like maybe the injectors are rattling?

actually it sounds like something in the combustion chamber, sort of like someone is rattling little shards of metal, making a rustling of leaves, but with metal shavings? sort of like that?
