Re: Engine vibrations, narrowed it down. Mon, 02 August 2004 12:49 Go to previous messageGo to previous message
mate that would definately be a bandaide fix! could also make things worse as you would be utting more pressure and strain on whatever is wrong.

if you bolt it up then whatever the problem would be wont have anywhere to release its strain, hence the vibrations. also it is highly unlikely it is bottom tensioner OR chain as you would hear the chain rattle on startup until oil builds up in tensioner.

so if there is no noise at atart up then its definately not tensioner or chain. the benefit of having a chain is the FACT that you can HEAR it when its stuffed.

this isnt something you hear all the time but when the motor is on, in neutral and you rev over 3500 have you tried holding the tip of the exhaust? i know it would be a bit hot BUT if the exhaust shakes as much as the plenum and as bad as the vibration then it would most probably be something loose (engine mounts, ex/in mani, etc) or overall engine balance off. i know the exhaust always vibrates but make sure it is the same magnitude of vibration.

also the reason it vibrates most at the plenum would be cause it is the least supported part of the engine. when reving can you notise the engine shaking as bad aswell? or is it just a feel and not visual? if its a feel then i would have to go for internal balancing (crank, rods, etc)
