Smoke on high rpm lift off
So ive been working on multiple issues on my 95 JDM FD. I suspect the ignition components and the PFC ive ordered will solve most of them.
However, I noticed yesterday that the car will blow a plume of white/blue/brown? (cant really tell windows are tinted) smoke at high rpm (6-7K) when I lift off the gas. Dosent matter if its in boost or not. I checked coolant and its not chewing up coolant.
I had a thread about my exhaust sound change. When I get to about 4500 or so the exhaust gets significantly louder (whether on boost or not) and the smoke usually follows that sounds change in the higher rpms.
Im suspecting a bad PCV setup or some such other issues. I had it into a rotary shop a while ago and they said they tested the motor and the compression was tight and the turbos seemed to work as they should.
The car is a JDM and has been sitting for god knows how long before I got it. Since it hasnt been running 100% ive only had it upto that high of RPM a handful of times. So maybe carbon buildup? I noticed a little oil in the intercooler piping as well, nothing excessive just enough to coat the pipe in some greasy-ness
