Perhaps, if tiny sand-like particles broke off from those pieces, and got ingested by the oil system........but who knows

pop open that OP (carefully) and see if there's any pitting or scuffing inside

Holy wuuuuuuuuuuuuuuuuut. O_O

I had a similar thing happen when i finally tore down the MX6 motor after 225k miles. I was on my 3rd turbo since 172k. The first one died a violent death when it ingested a flange adapter bolt that hadn't been sized properly. Second one slowly blew out the seals and got a bunch of play.

Imagine my surprise when i found relatively intact chunks of the first turbo in my oil pan...

FORTY THOUSAND MILES LATER


My cylinder walls were much more jacked up than yours, though. Motor didn't seem to care in the slightest.

I've given the insurance company all i can give. Next step is filing a complaint with DOI because it shouldn't take a month to settle a total loss claim and i'm super sick of driving Major Hater every day at this point.

Almost every vehicle i've wanted in the meantime has already sold, so i'm just not shopping anymore until i have cash in my hand. :(

Good call Comrade Vlad

Dammit all....

.005 feeler gauge slides under no problem, lots of pitting and scoring. Oil pumps ain't cheap either!

Yep, that turbo definitely didn't want to go peacefully, or alone.

I did feel like it was too fortuitous that the turbo blew and nothing else was damaged.

Ugh. I hate to ask, but have you pulled the cams to look at those journal surfaces yet?

I'm sending the head back to the shop to check valve lash and resurface the deck. I'll see what he says.

I don't see why they would be bad after being freshly rebuilt though....please god don't let that statement bite me in the ***.

Hopefully, anything post-oil filter will be OK.

Yeah I thought about that too, and also hope the same as Rick.

You really should check it yourself though, and really it's best done with head still torqued down to the block.

Make sure the head is checked and surfaced ONLY if it absolutely needs it. Your head has been cleaned up a couple times already, no? You don't want to end up with a det-happy engine like cordus from decking it down too much. ESP since you're on pump gas

Plastic or metal, ferrous or not (stick a magnet to it) will also help with identification. I mean, if its plastic that's not going to help, but you get the idea. in4answers.

Ahem. I stated that two posts before you.

Good it was finally figured out.

Yeah talked about that with the machinist. He said he is only going to do a skim pass to ensure a good seal with the MLS gasket.

I'm VERY happy in a glass half full way that I tore the block down. Any longer with these issues and this could have been much much worse.

So, to the experts: is that op salvageable, or is it toast?

I just sent an email with the pictures and information to BE. From comparing it to other "bad OP" it looks pretty hammered. I'll let you know when I get a response.
