sr20det oil smoke on decel

[joshfng]

Hey everyone. Pretty new to 240's and sr20's and am having an issue. My sr20det blacktop is having an issue. It smokes randomly after a large decel. If I take the rpms up and engine brake down, when I get back on the gas a puff of blue smoke will come out the exhaust for a few seconds.

My first thought was turbo oil seals so I pulled my charge piping and there are no signs of oil in them. I pulled the filter pipe off and checked for shaft play and oil and all is good, zero shaft play. It's a fairly new isis rs turbo swap from what I understand.

I checked my pcv valve also and it appears to be functioning properly. Only opens one way and not the other. I did notice there seems to be oil in the black lines running off the tee on the valve cover into the intake pipe and into the black catch can near the exhaust manifold. Is that a sign of something wrong?

The engine pulls strong, no sputtering or missing. I'm going to do a compression test to be safe but I'm hoping there are some other things to check first. Any help would be great!
