Yes, it is what they parent metal bearing, just machined into the casting with no bearing insert.
You should drop the oil pan and clean the pickup tube for oil pump and replace seals on the pickup tube and the other tube that goes from filter housing over to oil cooler outlet.
It would be a great idea to take off the oil feed line from front side of block to turbo and make sure it is clean in case the prior repair didn't get that cleaned out. If you have time the pickup tube and turbo feed pipe would be best cleaned by cleaning vat soaking at a machine shop or parts store with machine shop. Their cleaning tank chemicals will get that sludged oil out. Cleaning with brake cleaner spray and .22 rifle cleaner round brush is also good.
You may have to order those o rings for the pan, pickup, oil cooler feed, and turbo pipe copper washers.
I bet you'll find the oil pan could use vat soaking.

Great. I've already done the oil pan, and since seeing how bad it was I've been worried about everything else. I guess with good reason. I think I might check turbo lines. Since a impeller was found in exhaust! Still waiting on my seals to come in

Well motor is out. I now have a question. The flexplate moves , the center part on flexplate where bolts go through has 2 plates that look to be plugged welded together. But mine I can hold that center part and rotate the outer, which would be the plate and cranksensor relutor wheel. So I figure that explains why my timing was getting off ? The crank wasn't reading right and vvt would try to adjust and throw itself off. Explains why one trip drove good and then light a light switch it an awful

I'm shocked it wasn't making a whole lot of racket.

Well it would rattle periodically , and knock. I took it apart at the middle support washers ( flexplate) and the center around the bolt ring was broke all the way around And the back had a gouge on the back like a bolt had hit it, so I wonder if when the tranny was done they dropped one That's when the problem started

I'm done! I pulled engine out and flexplate was busted allowing the outer ring to spin which threw off crank sensor reading. I got it all back together and ca seems to run great. Thanks for help along the way

Same problem, 2.4T fails when I give it gas, starts great but as soon as I put a load on the engine it bogs down. I had changed my timing belt and tension.

On Alldata shows the timing set up is different for variable valve timing units and or with engines with different serial numbers? I set mine up not realizing that and am wondering if that maybe my issues.

see alldata picture, hope this helps, I haven't reset mine yet just using another car.

ask your question in a new thread, faster responses that waking up an old thread.

By the way, you'll need the cam timing lock tool to realign everything correctly. You probably have the timing off a couple of teeth because you did not realign the CVVT gear

You can watch this tutorial. It mainly deals with timing belt replacement and CVVT setup for volvo engine. I hope it will help.
