terrible engine vibration...
helly guys.. maybe somebody could help me identify the problem.. a week ago.. the car engine started vibrating very hard even on idle.. and when i accelerate sounds like a harley with dual exhaust... by the way a lot of white smoke...
Re: terrible engine vibration... (deathBooster)
That white smoke means you're burning oil. The vibration could come from many places, but if one of your pistons isn't working properly then it can destroy you engine's balance and therefore create a lot of vibration.

Blue = Oil, Black = Fuel, and White = Coolant sounds like you have a blown head gasket throw a compression tester on their and see what comes up... Also, If you don't have a compression tester and don't have the means to get one just check out your coolant if theres oil in there, or if theres coolant in the crankcase your head gasket is leaking. Or just start it up leave the cap off the radiator until the car warms up completely to operating temp if the coolant boils over you have exhaust gases backing up into the cooling system via blown head gasket as well.
But, then again vibration isn't necessarily due to a blown head gasket but you could have extremely low compression in one of your cylinders from the gasket being blown for a long period of time making a dragging effect in your engine essentially making you run on 2-3-3.5 etc. cylinders. Let me know what comes up, I know plenty about this I just finished rebuilding my engine due to a blown head gasket.

hey make sure to check ur gas injectors...my engine is doing that now and i had it diagnosed at the dealership they said one of my injectors was stuck on open so my #4 cylinder wasnt firing...
im not getting heavy white smoke...at least not that i can tell since its pretty cold out and exaust is fairly hot... so ya kinda always get white exhaust...anywho...
im pretty sure u have an engine missfire so find that one cylinder and pinpoint the problem...
once you have found the missfiring cilynder check ur coils make sure u have current running through it...check ur spark plug make sure its still good...and last but not least check ur injectors
if worse comes to worse take ur car to a dealership and have them run a diagnostic check with Consult.

^^ Agreed. If your engine shakes check out your injectors and do a wiggle test at the plugs. See if that smooths things out. Next thing to check would be your engine mounts, but unless it was real bad (before I changed my engine out, I had a torn transmission and driver side engine mount but still held in decently without too much shaking) so check that out.
