It shouldn't need to go that low. Is there oil in the intake? Look into it with a flashlight.
I have fought with oil in the intake. I have done the "tricks" you tube has described as being fixes-and they were improvements. 6 weeks ago I installed an Elite Engineering catch can. I am using a comp cams full shaft rocker set up and I wonder if it oils more liberally than the stock set ups and is creating my problem. Also considering reducing the orifice in the valve cover with a restricter, by like say 25%. It's a pretty big hole-no pcv valve here. And yes the catch can is catching some but not excessive.
I just saw that you have AFR 205 heads. Does the porting on those break through between the headbolt holes and the intake runners? I know when you port factory heads you have to use sealer on some of the head bolts to avoid sucking valvetrain oil into the intake ports.
No they don't on these heads. The oil I'm dealing with coats the intake runners and runs freely down into the head intakes. I've gained on this problem and thought I had it solved, but perhaps not...
Another avenue I'm looking into is the oil I use-currently Driven GP-1 10-30wt. Next oil change I'm gonna switch to Driven LS30 5-30wt It's advertised to reduce consumption through the pcv valve by limiting vaporization and foaming... and is specifically for LS engines.
IDK, Seems I always learn the hard way lol.
Learning the hard way makes the lessons stick, but it sure sucks getting to that point. I ordered a bunch of stuff when I planned to mod my GTO, but did not use the parts for a while. By the time I was ready, the ARP studs that were for pre 2004 blocks (oops) could not be returned. The Comp shaft mount rockers had something drip on the box and corrode 2 of the rockers. The wrong fuel level sending unit that came with my fuel cell could not be returned. A few other things went sideways, but you get the idea.
