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?

It could also be something as simple as a different brand of oil at the oil change performed after the flush. This is well known to quiet down an engine and vise versa. If there was a true blocked oil passage to the vvt solenoid then a corresponding code would likely be thrown. I wouldn't necessarily be going crazy with flushes due to one experience

I second this. As a rule i stay away from them. I did it as a kill or cure. I would advise anyone to stay away from flushes unless you have a problem.

In my case though i have used the same oil for years - Castrol Magnatec 5W30 A5 fully synthetic. After 160,000 miles/12 years i guess some crud built up somewhere.

Oh and the flush i used was a "Forte" brand and didn't cure my oil burning issues but i never expected it to.
