Replaced timing belt/waterpump/tensioner for the first time, everything seems to be tensioned properly, double checked the timing with a timing gun, everything seemed fine, only issue is a really loud vibration noise only in the cabin, double checked my engine mounts and they seem to be okay. I did find a ground lead running to the shock tower, but I don't know what it attaches to, don't think this could be my issue. I also replaced the torque mount on the one side which has a harder rubber than the old ones, but I dont think it should make THAT much noise. The vibration is most prevalent when you rev the engine, but it doesnt sound like a knock, and i did have the car on the ground and had the same noise. Any ideas?

Here is a video of the car running:

Any advice/ideas would be great.

 

Its idling at 1k rpm, and there is no performance gains from removing the timing belt cover.

 

Tension the timing belt as detailed in your service manual.

 

Car has always idled a bit high, used to be at 3k rpm before I fixed that. Previous owner didn't install the TB cover so I don't have one, car has been running fine w/o it for over a year now, I understand that there's a little bit of risk running it like that but it shouldn't effect anything performance wise.

Tension is fine, followed the proper steps, plus a service manual wouldn't help much as is a LS/VTEC engine swap

 

Why risk destroying the engine? Scout some local junk yards for missing parts as an insurance policy.

 

Post in the Hybrid engine swap forum where the LS/VTEC knowledge base exists.

 

Did you put the keyway back in the harmonic balancer when you installed it
