No. My only rattle was a cold start rattle. Here is an actual video of the problem



I replaced a ton of parts: The timing chain, the exhaust cam sprocket, chain tensioner, guides, VTC Solenoid, VTC Actuator, and Spool Valve assembly (may not have been needed). I forgot to order the crank sprocket.
Mechanic also did a valve adjustment as well.

About $1500 total for parts (I ordered OEM Honda parts online--$600, his labor--$900)

It is definitely NOT something to worry about. It does bother me when people categorize this coating with real "varnish", which is quickly (mentally) associated with sludge.


This is what I was talking about. People generally associate the brownish tinge under the valvecover area as "varnish" when it is not actually so. So that was my point to the OP, until you really know if it's "varnish" or "EP fallout" it doesn't really make sense to try to attack it... and since he's been using syn oils for a long time, it's probably more EP fallout.

This is varnish, and could become a concern:

This is EP fallout, and probably more likely what OP is considering varnish:

Well, I must say I learnt something today. I had no idea. Thanks for teaching me!
