Default Metal Shavings in Oil change - 04-19-2018, 05:12 AM

I posted this over in 2addicts but wanted to get as many opinions as possible. I'm wondering if anyone has any guesses to what the issue is and how to resolve it. What would the worst case vs best case scenario be?

I have sent 2 oil sames to Blackstone labs already, and I have sent the oil filter in for analysis at another lab as well.

Are there any relatively simple checks I can do like looking through the spark plugs with a boroscope? Or into the intake mainfold?


Just did an oil change and found some metal shavings in the oil pan and filter. I snapped a couple pictures attached here.

The pieces are not magnetic. And the scale shown it the picture is in inches. The round one measured .002" thick. The others were thicker. This is a small sample of the shavings. It's pretty difficult to quantify how many shavings there were. Maybe a small pinch of salt... Or 100 total shavings this size or smaller within 7 quarts of oil/ filter. It didn't not seem like a large amount. The pieces pictured were the largest ones that I saw.

The car is a BMW m235i. I bought the car brand new and followed the correct engine break in procedure.

The car is currently at 35,000 miles. This was the 4th oil change. The dealership does them every 10,000 miles. I decided to start doing my own change between the dealership changes. I just did this one myself at 34,000 miles. I also just installed a magnetic oil drain plug on this last go around.

The car is currently fbo with methanol injection. Last season I did a few hpde events as well.

So the question is should I be worried about these metallic shavings? How worried should I be? What inspections or testing can I do to confirm if it's an issue or not? Should I send an oil sample to Blackstone labs for oil analysis?

I know some metal shavings are normal with a new engine. Maybe since I tracked the car last season more are showing up from increased stress/ heat etc?

From the size and roughness of those pieces, it looks like it could be casting flash. Seems strange it would still be coming out at 35K miles. Post up your Blackstone reports, too. Did they indicate anything unusual?

I hope so. I let the oil drain for about an hour so I was hoping maybe it was still sitting in there because they do it quickly at the dealership.

I just sent them out. Hope to have the results within a week or two. I will post them up.

I would definitely be concerned
Blackstone should elucidate a lot for you.

Just got off the phone with the oil filter analysis. He told me what he found matched what Blackstone e had sent out. The filter was basically clean. The few particles that he did flush out we're idententied as aluminium.

No traces of other metals we're found.

I'm sticking with my original assessment of block and head casting flash. I think you're in the clear. Just keep your oil changes up and you might want to do and oil analysis each time, just to stay in the know on what's going on with the motor.

Those are my thoughts as well, and that's my plan as well. Good to know someone else is the thinking the same thing.
