OCV/VVT and filter removal need oil drained?

It was a very tricky job to get the plug undone and fish it out with pliers. One of the little plastic tabs on the end of mine was missing but i couldn't see any debris in it. That said 10,000 miles before that i ran engine flush through for 40 minutes because of a timing chain rattle which the flush cured.

So evidently the tensioner or VVT cam was losing oil pressure. The flush fixed it.

Wow. This cure is important to know, and first I've seen here where a number of engine rattle at start-ups have been posted. What did you use for the flush? Would it also tend to remove the carbon causing stuck piston rings?
