I've been off this board for many years, but I recently found my back to find solutions.
My 09' Tahoe has been steady, clocking in at 189k; traveling sales puts on the milage. But the 'Oil Consumption' has increased which I need to change...So I replaced the Valve Cover (but in the process received the slightly wrong cover (the pcv port was of a different design and the oem hose would not connect), so I took the next logic step and went Catch Can shopping (as this would ultimate solve 2 things; most importantly was replacing the oem lcv hose(s)...
However, I ended up with 'rectangle Catch can', the mounting hardware was bleak so I improvised some and made a bracket work..etc..and got it nicely connected and solved my first problem with the valve cover- yeah!
What I didn't expect was any performance at all to making the mod, but my Tahoe feels like the chains have come off and come to life- the response is quite noticeable, the sound is slightly deeper and it just wants to go....I know I must be psycho schematic...but either way I'm enjoying the new ride. That said it seems my old pcv valve/hose must have been doing more harm than good......
Now I want more... Air intake, tuned, big brakes and 2/3 drop....I knew I shouldn't have come here
