Vibration in engine
 

Hey i wanted to see if anyone can help me with this diagnosis it's an 86 NA i have been having a vibration in the engine that's noticable 2,000 rpm's and above gradually gets worse the higher the rpm it happens with or without the clutch engaged I tried to see if i can see where the vibration is by looking at it under the hood but it's only noticable in the car it's not motor mounts beacause they aren't moving if anyone has an idea let me know
