Hello everyone !

My 1991 ZR-1 with a 1990 engine tends to smoke oil. I know the 1990's don't have an exhaust seal so they tend to smoke when starting up, I also know that oil can build up in the plenum when driving at low rpm, and as soon as you accelerate the oil is sucked in and burns and causes smoke. but my Z smokes almost constantly, in slow motion she doesn?t smoke. but when accelerating it smokes blue. she doesn't smoke a lot but too much for me. ever since I have she has always smoked that way. I changed the injector housing gaskets a few months ago, I also changed the hose with the dual PCV valve. but a lot of oil (I think) is building up in my PCV system.
After 60 miles the hose with the dual PCV is "filled" with oil (see photos) I can also see a lot of oil in my injector housing (see photo) I tried to unplug the system to see if that was changing something..i just speeded up a few times for about ten minutes, but she was still smoking. (I disconnected the vacuum line from the PCV system, the 2 grommets and the ducts connected to the cam cover. I noticed that the filters on the cam cover were decomposed or even absent on one side. I plan to replace them. but I don't really understand their goals? for information, the engine has 80k miles, with the secondaries removed, a Haibeck chip, 16 new injectors, coils, etc. it does not have cats (obx headers) and the car runs very well . the compression test is very good, and all spark plugs have normal color (not oily).
in my opinion the problem is with the PCV system compared to the oil that I find in the system.

I hope you can help me, I may be paranoid and that is quite normal for a 1990 LT5 of smoking oil (blue smoke and smell of oil)
thanks in advance for your answers.
