engine vibration

[LTUDSM]

ok guys here is my deal

couple weeks ago i changed my motor mounts to prothane ones.the car was a lil bit shaky,thre days ago while i was driving, i noticed thats i have a big vibration from 2000 rmps to 2500 after 2500 it disapears.it doesnt matter if i rev at idle to 2000 or while i drive the car the vibration stills there. I was reading about the engine vibration and everybody is saying,that vibration could cause bad motor mounts or balance shaft,my mounts are almost new and the balance shaft is good too.All the bolts are tight really good.tranny is in great condition no oil leak ,gears are shifting smoothly.No CEL what so ever.I noticed that when i start the car ,it doesnt matter if its in the morning or after driving the blue smoke pops out of my exhaust and disapears.While im driving i got no smokes coming out.I don't know if that supposed to do anything with vibration. Come on guys help me out ,im totally lost here

When you go with stiffer engine mounts, you will feel alot more vibrations than with stock motor mounts. This is normal.

As for the blue smoke. That sounds like your valve guide seals need to be replaced.

From what I deciphered from your not-so-great description, I've come up with twothings. One-you will feel more vibration with 'thane mounts. Don't know how much you are ctually having to tell if it's more than normal.
Two-smoke coming from your exhaust shouldn't have anything to do with the vibration. But if you've added some kind of fuel control, and it's way out of whack...that could lead to a bad vibration in your motor due to a very terrible air/fuel ratio. Don't have enough info to tell though.

no its not normal,like i said before, When i put a new motor mounts (prothane) it was a lil shaky after the stock motor mounts ,But after a week i was driving and after a hard run i felt a big vibration from 2000 rpms to 2500. (with prothane engine mounts)
Here is the Video you can hear a lilbit how everything vibrates from 2000 rmps

That almost sounds like a timing belt tensioner to me. It may just be your exhaust.

If the car feels more sluggish than what it used to feel like, then it could be your balance shafts.

i took a car to mechanics but they did find the problem,they checked timing belts and marks,plus balance shafts they all were good.

The stock mounts are soft which cause you to feel less vibration the prothane mounts are solid so you feel everything you didnt before. So your motor is most likely vibrating just as much as it was before you can just feel it now. As for the smoke the other posts pretty much covered what could cause that.
