S40 Engine B4204T3 Blue smoke when idle

Ended up grinding down a box end wrench. I'm able to get wrench on but can barely get any turns on it. Bad design.

Bad design.

The S40 is a subcompact. Like any compact or subcompact there is not much space for the engineer to work with. Not much space is the nature of compact.

Engineers cannot bend the laws of physics ... tho some do dream of constructions that are bigger on the inside then they are on the outside.

So true.
Though I like wrenching on cars, the S40 is not what I'd consider a pleasure.
Everything is just so tight.

Can a S40 can run without a turbo charger? Thought I'd ask. Ordered a cartridge but didn't sit flush in the turbo chassis. Sent it back and looking at new one just under $300.

I think there were non-turbocharged S40s in other markets. But not sure the 1.9L was used.
North America only received 1.9L turbocharged models.

You've got an interesting question.
My brain says the ECU would have a hard time compensating for a missing turbocharger,
but I've got no empirical evidence to support that.
Your post makes me think that you will remove the turbine. If that's the case, how will you block off the compressor housing?

Post results if you try it.

The new turbo is in and seems to be running ok. I understood there would be smoke for a while since the exhaust wasn't cleaned so oil build up will have to just burn off. When I first started, I expected smoke, it finally stopped. Feel goods to have it running. Next project is a s60 transmission issue. Hope there's a product that can be used to flush out buildup. Dealer says the oil is lifetime rated so doesn't see how changing fluid would help....Will start a different thread on that issue. Thanks for all the support given.

As I thought, the smoke eventually stopped. New Turbo seems to be working great. Now, I'm getting P0017 code and put an oscilloscope on the top sensor and it seems to be functioning as designed. Voltages look correct.
I've read where low oil could cause this code. Would any of the vacuum lines cause this code?

Updating subject line to reflect solved.

Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor 'B' is the code.

Found the oil vent pipe coming off the bottom of turbo housing into block was seated poorly and gasket was passing oil. Had to pull the turbo just to be able to take pipe off turbo. NOT HAPPY. Local Volvo dealer closed so ending up making a make shift gasket out of a rubber grommet. Put it all back together and P0017 code cleared. Getting code P0018 now. (Water Temp)
