Hello, I have a 2006 Escalade with the 6 liter LQ9 engine, that has the valve cover with the integrated PCV valve. My oil consumption is about 1 quart per 3000 miles, which I personally find a bit high.
I have read that the clogged hole in the baffle plate, or the PCV valve can cause that.
I know from other cars with the appropriate crankcase ventilation that you have a slight vacuum, when you lift the oil cap with the engine running and put your hand on it. At my engine I have neither pressure from the crankcase nor any noticeable vacuum.
To compare if this is normal, i would like to know: how about that at your cars?
Or Is there another way to check the installed PCV valve, without disassembling, before I order a new valve cover in the USA?
Thank you folks
