The turbo is not the original one off of the 850’s it is the bigger 16g, I am assuming there is a step kit for that as well?

For sure. And as stated it is probably a 16t, check the ID plate on the turbo it likely says TD04H-16T

It is a TD04HL-16T

I just ordered a rebuild kit for my 16T. About $55 plus expedited shipping from gpopshop. Worth a go. Mark the shaft and compressor wheel before you disassemble it and you can probably get away without rebalancing it.

Long story short. I installed oe breather and oe hoses to breather, new 5/8 hose and am installing a 5/8 inline catch can. Ordered all of the stuff to rebuild and reinstall the turbo. Smoke is almost gone but the oil cap is still pushing oil out even with a new oe cap seal. No smoke from the dipstick. While off cleaned all the ports and seafoamed the top port. Let it sit overnight then changed the oil. I am convinced it is now either the turbo building crankcase pressure or the rings. We shall see once the turbo is rebuilt.

My oil cap continued to leak even after replacing the gasket (and passing the glove test). Bought a new Volvo oil cap, fixed the problem. After 20 years of heat, I think the caps deform to the point where they leak no matter how nice of a gasket you use.
