is there anything inside the catch can?

Nothing yet. Just condensation. So should I add a hose from the preturbo nipple instead of the filter or leave it as is?

I looked at various setup's in the end i just said bollox to it and bought 2 catch cans.

The coldside has a 1 way valve as well as the PCV to stop the boost pre cam cover.
The other catch can is just connected in between the cam cover and filter.

if you want to route it back, fill the can with something to catch the vapors. I've used used steel wool in the past, but be warned it may make its way into your motor.

if it was my setup I would leave it as it

xveganxcowboyx and I did both the compresson and leak down test yesterday.

Dry 2nd cylinder was 205psi, third cylinder was 170psi.

Oil in 2nd cylinder bumped the psi to like 235psi, if I remember correcty.
The third(bad cylinder) went up to 250psi with oil in it.

Leak down test showed moderate leaking on both 2nd and 3rd cylinders, a bit more on the 3rd.

We could not hear the air in either the exhaust or the intake. The only place we heard the air was through the oil filler cap.

However I noticed that the car smokes a lot only after hard boosting and only at idle after hard driving. When I drive nice and don't boost there is hardly any smoke. And we noticed that my drain line on the turbo goes horizontal for a while before it enters the oil pan.

I am going to remove my ac compressor that is in the way of the line an see if making the line go totally straight down will help.

I know but I don't think it would be smoking tag bad with one ring bering bad. And 170 is still pretty good compression.

Had my friend drive behind my at night and the car smokes a lot! How would I check if my turbo seals are bad? I know my cold side is not leaking. The intercooler is dry.

took the DP off to see if there is any oil on the hot side: no oil, no shaft play, just a lot of carbon build up.

I wouldnt think youd see much blowby from 170psi either, but 250 wet sounds suspiciously high. I'd be willing to bet the gauge is bad and all your readings are are off by 40-50psi.

Is there a lot of smoke coming out of the oil cap?

no smoke out of the oil cap. We used two different gauges. high readings are probably because of the oil collecting in the pistons. I am going to redo my catch can and see if that helps.
