coolant staying clean? If yes, i would say stuck egr everyone has been having hell with thoose egr valves if the coolant is getting dirty a headgasket, but the coolant can stay clean with a blown headgasket In my experiences the oil analsys will not tell you if the egr is goofed but it could tell you about a blown HG, but for the cost of it you can not go wrong. I get them on my trucks and change oil according to them. or the egr cooler is leaking into the exhaust, sometimes the coolant will crystalize in the exhaust when it does that
