A good friend of mine wanted to take my car for a spin, so I let him go for it. Heres where it gets interesting, he floored the car a few times and I heard a noise. The noise was like a rattling or tapping sort of thing. At first I thought it might be my grill loose or something, but that wasnt the problem. I called another friend, who knows his stuff, and explained what the noise was and what was going on. He came to the conclusion it might possibly be my valve being off. I was wondering if any one has ever had this problem or someone knows what the problem might be and how to fix it.

 

go buy a compression tester and follw the instructions (it won't tell you to remove the sensor from the drivers end of the camshaft- but you need to to keep from jetting fuel in the cylinders when you turn the engine over). If your compressions are at least 160 then it's not your valves. Actually, if you have valve problems, chances are good you'll get really close to zero compression.

And what have you done to your engine? If it's nothing involving the cam gear, cam or head it's probably not the valves.

 

sounds like it may be a possibility, lesson learned tho i bet, that y i dont let n e one drive my car..lol.. good luck

 

I just changed the oil other than that the engine is 100% stock. Lol im not blaming him for it.

 

wait- at full throttle you heard the rattle or after your drive? Because if the rattle sound is at idle, it's just your lifters and there's nothing you can do about it, so don't worry.

 

I hear it slighty while im ideling and its when I get to high rpms (5k) were its REALLY noticeable.

 

well if you haven't done anything to the car, take it to the dealer and explain the situation to them fully and have them ride along with you while you replicate the noise. But for an unmodified car I'd say you have very little to worry about.

 

I hope its covered under the warrenty.....

 

Bump!

 

i agree with previous posts, if it's stock and you've maintained it changed the oil etc you should be fine... unless you're running out of oil in which case you will hear it at idle and all rpms, but louder at higher rpms. it's not a sound you want to hear!

definitely get it checked at the dealer asap

 

with my old engine when i let off the gas at high rpms it would make a horrid noise at high rpms

 

I agree, but I had well over half tank gas and i just got a oil change the other day.
