If you were off one tooth either way it would not start or run as good as you state.
Don't take it apart........
Use the Mechanic Stethoscope, a Long Screw driver directly to your ear. you can isolate the noise better that way unless you have or could borrow a mechanic stethoscope.

 Well Here is the Entire Parts Store of Mechanic in a Can. All just Petroleum Distillates and Marketing Hooplah. Does little to Nothing mostly Nothing but receive your wallet. This is 36 years experience on the Application alone. This would just expand enough on a hot day under load to stick open for 20 minutes or so then cool and snap back in place,start run repeat. As it did stick it still did Not Burn the valve on the flame travel side. Now the Sicking Valve does Stop it from Rotating its lil bit on every hit I have had Lots that Did burn to a Un-refacable Valve. Some even used Stelite coating on the Ex, but really didn't matter. The Above Valve and Others also enjoyed More than regular oil Changes, Dino to High End Synth, Stabilizers, Cleaners etc. And unless I'm at mechanic in a can why would one take apart a engine, finds its gooped up and put it Back together and add Mystery Oil? |

I used the flange style and the exhaust is very tight I would still look at that gasket. You can get the bolts tight, but if the flange is not right it can still leak. Listen to the video you posted when you hear the sound the muffler sound is in time with it.
The flange is a bit hard to get to seat right. That is why you need everything a bit loose when you tighten it down so nothing will bind and interfere with the tightening down of the flange. If it does bind it may be tight, but not sealed.

Use the Mechanic Stethoscope, a Long Screw driver directly to your ear. you can isolate the noise better that way unless you have or could borrow a mechanic stethoscope. I had a race car mechanic listen to it with a stethoscope (Luckily one next door to where I work) he said the engine sounded fine! But the noise is driving me crazy. something is not right somewhere... and I'm afraid to drive it for fear something major is going to happen. I've checked TDC and it is fine, I've pulled the variator off and started it and it still makes the same noise, so it's not a bad roller or anything. The chain issue sticks in my head - when I was setting the piston to TDC the chain slipped off the sprocket inside the engine, behind where the variator sits. I put the chain back on the sprocket and went on my way to putting it back together. It is in THIS area where the noise is coming from. It is as if something is loose and rattling inside. |

the sound is coming from no where near the exhaust. it is coming from inside on the bottom, right behind where the variator is and where the chain sits on the sprocket. I've pulled the exhaust 3 times and a mechanic with a stethoscope listened to it and assured me it was not the case.

Ok cool on the mechanic listen. A noise of what you explain in the internals would Most Likely caused a Failure by this point. Hold off on taking it apart..... Do a run thru check of the time chain tensioner as you looksee with the Valve Cover Off. I would think if the CamChain is flapping round in there its more then enough to jack up Cam/Valve timing and would run poorly, but on the other hand you say you quad checked the TDC Cam timing and is Correct?? |

here is a pic with my finger pointing to where the noise is coming from  |

Yes I've checked TDC by pulling the spark plug and watching the piston and it coincides with the mark I put on for TDC. the engine runs great which make me believe it is right on the money. The chain is tight, the cam chain tensioner seems to be working as it should. |

From what you indicate, Its running to darn good to take apart.
Clapped out Cam Chain Guides to the point the assy makes noise I would cause inconstant tune and one would notice this.
Can you Video up close?

Pulled the valve cover and looked down into the engine and chain and guides all seem to be where they are supposed to be... So i know everything there is correct

here is the best I can get without getting the camera in the variator. with the CVT cover on you would swear it was a roller bouncing around, I took the variator off started the engine and still the same noise. it sound like something is bouncing around inside, somewhere. when you rev the engine it gets less noticeable but still there. If you put a marble in a jar and shook it up and down, it would sound the same It never made this noise before the original problem. |
