Vibration
I seemed to have developed an engine vibration at high rpms that I don't believe was there before. It only seems to be there when I go over about 5k rpms. It's not real severe, but I don't want to ruin my motor. Its a really high pitched vibration which seems to correspond to engine rpms.
The engine still seems strong and everything, but I'm afraid to take her up to higher rpms until I figure out what's going on. I'm pretty sure that the engine is what's vibrating, doesn't make a difference if the clutch is in or not. It almost feels like the exhaust is rubbing on the frame, and I haven't been able to check this yet, but it wasn't there before and the exhaust was installed about 8 months ago. What could cause this vibration? Thanks... |
could be the driveshaft

Thanks for the input, but no. The vibration is consistent with engine rpms and does not change with vehicle speed. I've experienced driveline vibration before and am confident that this is not related to the driveline. Thanks...

How long has that engine in the car ? There's a couple of different things that could be the cause of this vibration ! So, now if the engine was recently pulled or not is where i would start the process of elimination.

Original engine, untouched with 190,000 miles on it. No oil loss or burning. Vibration is not severe, but I seem to recall that a rotary that I had before was very smooth all the way to the redline. Thanks.

Found the problem. One of my exhaust hangers came loose allowing the exhaust to rest against the frame. Back to silkey smooth high revving once again! :)
|
how did that cause an rpm dependant vibration?

that is what i figured would cause it, but i didn't think it would be that significant
|
Yeah, it wasn't real bad, but thinking it was coming from the engine I was pretty concerned about it...
|
ahhh, I have the same problem and it must be the same thing, I just installed my racing beat exhaust myself and didn't hook up some of the hangers because they were too rusted and stuff, I need to get it into a muffler shop to get them to fix the mounts up...
|
when i installed my rb exhaust i didn't hook up some of the hangers and it made a kindof squeeking sound, not really a vibration
|
I had that for awile before my engine blew.
|
shoo, go away before you infect my engine and it blows
