Default Smoke on start from engine right side

Hey all, could use a bit of information. Last time I drove I noticed a burning smell from the engine. Today I opened the hood (imgur link) and noticed quite a bit of smoking from the right side of the engine when I started it up. This seemed to go away after ~20 seconds or so. Any thoughts? Happy to provide more info. Thanks!

I was expecting to see. Smoke one side of tail pipe.
Good news. Is. Miniscule.
Looking at the clip. Smoke was very clear. Went away very quickly.
The silicone VC gaskets are amazing. With that said if original. I would inspect the easy side.
It is possible you could have a leaking knock sensor,
Coolant sensor. Even leaking dipstick.
A bright light, close inspection. Should help you pinpoint the precise location on PS. Jack the front up. Inspect underneath you should easily discover the pooling trail.

Most likely valve cover leaking down onto exhaust manifold.
