Metal shavings in oil - clogged VVT solenoids
My 07 redline (160,000 miles) was experiencing a rough "rocking" idle here and there recently, just before my last oil change. On my last change, I put in a bottle of Rislone thinking it was sticking valves. That seemed to help but not cure the issue. I also noticed in the oil when drained little bits of metal shavings. Not much, just a glistening.
Then, just last week it threw a P0011 code, while doing the rocking idle. Google says it's the VVT solenoids on the top of the engine and they are typical to fail. Ordered Dorman 917-215,216 from Amazon and replaced these today.....
Well....... the old solenoids, which electrically tested fine, were clogged up with these bits of metal shavings!!!
The good news is, the engine is purring like a kitten now. Even when it wasn't rocking back and forth, it didn't sound 'well' at idle, and seemed sluggish when stepping on it. No more of that.
But, I am worried about what is causing these metal bits, and what happens when it runs out of metal.
The bits are magnetic, and I guess I will be buying a magnetic oil plug as well. Anything else anyone can suggest checking/doing to prevent this from becoming a big problem?
