Hello, my wife drives a Mazda Tribute 2.3 AWD in which a Princ gas system is installed. The Tribute has now run currently 213,000 km and has a very high oil consumption, I think, so 1.5 liters on 1,000 km, but can not see what it could be. Also in between times the lamp for engine failure goes on, but after different times (days or weeks) again. We worry about the very high oil consumption already serious. But he smokes no Do you have any idea here in the forum? I read here in the Mazda forum about a PCR valve, but it was with another model. Does the tribute also have this valve? If so, could someone please send us a photo, where you can see the installation location? Otherwise we are more than satisfied with the vehicle. Thank you very much for your help. Many greetings Capri-Andi
