385km later, it started knocking and my engine died.

Just to be sure, keep checking, keep "being paranoid" about it for a while, and if you doubt, bring it back asap.

My first problem was the day I got it back from the dealership after the recall. Turned out to be a bad ocv. Got it fixed a week and a half later

Two weeks after picking up my car again, my engine failed on the highway. Spun a rod bearing

Hey Ermax, listen to this and let me know what you think.



Thanks,


Happens only in gear, warm engine, letting off gas, around 1500-2000 rpm.
(dealer tried to tell me the noise is cuz engine is about to stall)
Or sometimes does this at cold star for few seconds.

Sounds only under these circumstances. Can't make the noise in neutral. No noise at higher rpm, or when giving more gas.

Sounds like rod knock to me. Rod knock makes the most noise on a cold start and then when not under load. So like when you are in between gears and the engine is transient it will knock and then when just cruising. It typically goes silent when you give it some gas or heavy engine braking.

The car does make noise when bogging the engine but what I hear in the video definitely isn’t the sound it makes when bogging. Did they hear this video?

This is some sad shit.

[msaikhan]

They heard more than the video. I drove around with service director, service manager, master tech. The director and manager straight up tells me they don't hear anything. Or they tried to tell me, i'm going too slow in gear when i'm above 1.5k rpm, tried to tell me engine is bogging.



Master tech was coming to test ride, and i can see the service manager next to him, saying stuff to him. When the master tech rode with me, he said he doesn't hear it. But it become so damn obvious, he was like, oh i think i do hear some tapping. And he tried to tell me its because of the cracks in the header. THERE is small crack in the header, and because it's aftermarket they trying to blame it on header. I told em i'll put the stock one and come back. WHOLE f***ing service department is shady as F***.

Want to see something else sad? I just drained a quart of oil out, as suggested. Here's two fun pics of what was in that sample. Just sent a sample out to Blackstone. What should I expect from the dealership? This was about 600 miles after having the recall done.


Pics were taken of what was left on the bottom of a clean pyrex four-cup container sitting on a white paper towel after pouring the drained oil into another container for safe-keeping. Everything you see was in the oil, and is NOT dirt underneath the glass.


Thoughts?

And I’m sure a bunch of that crap is in your pickup. I’d suggest changing the oil and filter ASAP but that would also throw out evidence so instead I’d stop driving it and take it to the dealer to do an oil change.

Does it feel like rubber?

You could be bogging at 1500 if you are heavy on the gas but cruising at 1500 will not bog. Again, what I hear in the video isn’t bogging. It could be a cracked header I guess but that doesn’t explain why the sound changes with load. If it was a cracked header it would resonate at a particular RPM regardless of load. I’d throw the OEM header on there and get it back to them and see what their next excuse is.

Hmmm.. the quote thingie isn't working for some reason. No, that stuff doesn't feel like rubber, it's very hard and sharp feeling when you roll it between your fingers, and you can't crush it.



Sigh....

Yea, that's my next move. have my feet completely off gas pedal at 1500-2000 and it makes that noise.

Could be bearing material. The bearings have a few layers of material. The outer layer is dark and the center is brass and will sparkle. If you shine a flashlight on it do you see swirls of gold reflective material? I guess it also could be carbon deposits.

To give you an idea, the bearing on the left is toast. The brass has completely flaked off. The bearing on the right has brass starting to peak through. A good bearing should have a uniform dark gray surface unless it’s been deprived of oil.

Looks like dirt to me. probably washed in to the pan when the engine came apart. Heavy enough to settle to the bottom of the pan and not get sucked up.

Bearing material is obviously bearing material. You'll have nice oily/shimmery stuff on top and metal on the bottom.

These are not Subaru engine, but you get the idea. First one was a nice deep thud thud thud, engine replaced under warranty. Second one was a crisper bang bang bang, the majority of the bearing material was gone at that point. Also required a new engine, on a brand new van.

After the recall within the next couple days I did an oil change. I bought a new black oil pan and didn't think to inspect it after I poured the oil out. I'm going to give a close look to the surface of the pan and hopefully not see debris left over from the oil that the tech put in.

These reports are freaking me out, I'm at about 150 miles since the recall and everything is running fine, engine sounds are same as they where. This weekend my plan is to try and rack up miles and see if something goes wrong.

At what point do you guys think one would be out of the woods in terms of issues from the recall. I'm guessing if nothing goes wrong in the first 1000 miles after the recall service, then I'll probably be okay?

My thinking is based on the reports on this forum that seem to be from 200 miles to 700 miles in which the engine failure occurs following the recall service.

What do you guys think, is the overall life of the engine shortened by this recall? Is 1000 miles since the recall with no problems a indicator things will be okay?

1K seems about right to me. If the bearings are starved of oil they aren’t actually bearings anymore and disintegrate fairly fast.
