White/Blue Smoke from the Tail Pipe 97 R Wagon

When the original hose did not cure it, I did the mod and went with the up sized hoses. It does pass the glove test.

TCV has been drilled as big as it can be to still give the hose clamp something to clamp to.

Sorry not TCV , PTC was typing to fast for my brain

That should be fine, but you'll be smoking both white and blue if the two top hoses on the oil trap are switched around.

They are correct. Left rear top hose goes up to valve cover and the one more center on top of oil trap to ptc.

A little confused here. The port you open up on the PTC is on the base of it, not where the hose clamps.

Sorry for the confusion I have clamps on both ports

This is what you opened up, correct?

I don't think the PTC mod has much positive effect as claimed (my opinion). By drilling the bottom larger only when the throttle is open will it help a little. When idling that hole being larger hurts the system, as the throttle is shut the small vacumm line that is attached to the PTC will have a harder time clearing the gases from the larger PTC hose when it's able to pull air more easily from the bottom of the PTC opening. What is beneficial and was later done by Volvo is adding a quality one way valve along the small vacumm line going to the PTC, having it orientated so it can pull vac and crankcase gases but block off the flow of positive air from going back through the PTC and into the turbo when on boost. Makes sense? Better clearing of the crankcase when under throttle, plus no boost leak which is what happens without that check valve

Sorry took so long to get back to you all and thanks for all the help. That is not the port that we drilled. We drilled the port with the small hose going in which I am sure ruined the valve. Ugh. I will source a new intake tube and will put the in line check valve that was suggested. As far as the turbo, it is dry no oil leaks. This is another link for the one I bought if you all think I should change back to stock I am completely down with it just want you all to look at what I got and see if this all could be self inflicted. https://www.ebay.com/itm/Turbo-FOR-Volv ...

Last one more mention here is that there is oil pushing out from the oil cap. I forgot to mention this before but thought it might be something to mention in all of this.
