The following complex problem is an Escort Built 91 with 1.4l engine; 150Tkm (control unit changed from Ford in ’95 to Kulanz because of high consumption and low performance) The oil consumption of the car is already considerable. In the summer it takes a good 1.5l to 1000km in mix (50% city, 50% overland) Therefore, the oil exchange intervals since ’95 have almost never been observed, as one has only refilled. The oil exits on the valve cover, which can certainly be easily repaired. a considerable rattle from the engine came to this problem…(like metal himself) An excessively blue or white smoke in the exhaust gas did not notice. The AU also passed it again… The fuel consumption is at 10l, under it goes nothing. In addition, there are now still speed fluctuations, which make driving very difficult… How can I get to the bottom of the above mentioned problems or test them? To all excess the car rusts..so fast you can not weld..-> What ka nn to do against the edges on the wheelrails?
