Hey All, hoping to get some answers.
Lately, the engine is very labored at high RPMs when asking for more power, including some misfires.
There is a vacuum in the crankcase and valve cover.The engine runs MUCH better when I open the oil cap or dipstick.
All of my research had pointed to replacing the PCV valve (part of the Valve cover on this model engine)
I now think that there is a breather valve but cannot find its location or what replacement part I need
I have changed the Valve cover (PCV Valve is built into the Valve cover)I have a Haynes manual and it has not at all been helpful in identifying the issue or the parts needed since it seems to be focused on the older models which are very different.
Am I on the right track with a breather valve or hose?If so where is it located on this engine?
Anything else I might be missing or should look for ?
