Metal in oil filter and on magnetic plug

[Jake Raby]

Based on the size and shape of those particles collected on the drain plug, I'd expect that you have a failing camshaft/ lifter in process.

I would pull the sump plate and look for more. I would also pull the swirl pots and pull them apart. Since return oil from the cylinder heads/ valve train area passes through them, they collect a good bit of debris before it gets to the sump. The side with the most debris is the side where your issue lies.

Most importantly, cease operation of the engine until you find the source of the issue. With all this debris being generated as the engine runs, it's destroying its self from the inside out. It will run perfect until it pops, then you have thousands of dollars worth of collateral damage to contend with.

Please don't drive it to death.

That certainly makes sense I got a variocam actuator cel a few weeks ago. I don't remember the exact code number but it was bank 1 variocam actuator fault.

There ya go... Its not the actuator, thats just whats out of range from debris generation and wear.

Tear it down.

I think the thing you learn most from reading these forums over the years is who you can trust. It is amazing to this humble observer how the same 5 or 6 people so consistently contribute to our knowledge and help people out all while running their day jobs.

Treat them kindly lest they burn out.
