-yeah i did the ccv during winter a couple year ago, and didnt notice any difference at the time between the before/after lol...


when i use to have valve cover oil leak , the car wouldnt start at -20C but if i wait couple days when its warmer around 0 it would start like a charm...


i dont have tool to check pressure, i guess i have to make a tour to a garage, i hope its not the valve cover gasket.. as i just did it during spring... but i guess the chance are here since i smell a burning smell ... only today since the repair
