You have to remember that every engine is different the key word here is some "The LSJ DOES NOT HAVE A COKING ISSUE it’s not a DI engine, but the LSJ PCV is a two-way system and is not very effective and some S/C cars pop dipsticks out as the crank case pressure builds up at high revs."(The IM and intercooler on our engine were, btw, free of gunk.) (Proof, btw, that the stock crankcase-venting config had been doing an excellent job.)
Here is a perfect example I have two Tahoe's in my work fleet built in consecutive order only difference is last digit of vin# one of them will run 7000 miles between oil changes not use a drop. The other one will use a quart of oil on an average 1500 miles. Oh yes it has been addressed with GM " we do not see a problem"
I 'm adding a supercharger to my tired 2.2. I do not think it is any different of a setup for the PCV than the 2.0 S/C. I am fully expecting blow by and being one of those SOME cars. so I have the catch can ready to install. I have cleaned the cores once and do not want to go back down that road again. I am glad we are not using a GDI engine and have to deal with the build up on the valves.
