Does the vibration happen allt he time? Is the vibration worse in Drive then in park, or at different RPM's?

Do you feel AND hear the vibration?

Yes I feel and hear vibration but the car is working good (Speed,Transition all are goods).
This vibration is happened suddenly after change Gasket, before that the car is working very very well.
Please give me a photo that i need to check because may be misunderstanding will happen.
Thanks for helping my friend.
Where is the sensor or another spar parts related to RPM's?

[ASG14]

RPM's, Tachometer (Revolutions Per Minute).

Also, check the Passenger Side upper motor mount. See if the rubber is broken/ripped/torn. This mount being bad can often cause a vibration.

I have the same problem. I recently changed the valve cover gaskets and the engine started vibrating later on. It vibrates on low rpm, low speeds, and complete stop. I can feel the vibration inside the car. I dont know what it is. Maybe its the timing, but I dont know. There are some weird noises coming from the timing belt area(the cover). Could it be the crank pulley/harmonic balancer? And ever since changing the valve cover gaskets, once or twice I've seen oil around the cap and around the valve cover area. Vibration is higher when in Drive and Reverse. There's little to no vibration when in Park and when the rpm is lower than 2000. Before the valve cover gaskets were changed the engine wasn't vibrating at all.

This is a 3VZ

Check and make sure the PCV valve is plugged into a vacuum source and that the hose is not cracked or kinked. A vacuum leak would explain the excessive vibration after VC replacement, and oil under pressure being pushed out the oil cap.

I wish I could, but I don't have the v6 in my Camry. Basically to do the rear VC gasket the intake plenum had to come off. There are a lot of hoses that connect to the plenum. I would just look anywhere you can see on the plenum for a loose or missing hose.

Open the pdf titled "1MZ-FE Engine (V6) (24.92MB)"

Look at pages EG2-200 and EG2-201 which talk about the PCV valve and how to test it. Other pages near those talk about other components of the vacuum system and hoses.

Thanks Lot for this Info. after I check i found the PCV valve is Ok after i Blow it from two sides by the same way as manual but i found the hose is very strong and the two sides are simple cracks.I'll try to change total hose & inform you what happen.

In the week end
I changed total hose & check PCV but unfortunately vibration still going.Could you please take a snap shot (Photo) for all small hoses.I think a mechanic didn't connect very well.I'm very tired.Please give me another possibility for vibration.

Any ideas please share me your information & suggestions.

Pull up the Manule and cheak to make sure all hoses are canected right. ( take your time it's easy to over look ) also cheak the vacum lines with the car running. If thay get soft thay will calaps and not alow proper flow.
