servus! I have the problem that oil is present in the air filter box at the Escort (bj’95, 1,6l, 90ps, 16v) with 173tkm of running power. the engine consumes relatively much oil since anyway and abruptly, but loses nothing at all. in recent times, the problem has still come to me that the engine, which is powerful enough for the air filter box, has no more power. I have to push through the accelerator to reach the 80km/h in the 3rd cycle. with the fourth one, just 130km/h is possible. I have to ask: 1. does one have something to do with the other (oil has always needed a lot, but the performance was always top until just recently)? 2. can one repair the thing with the oil and if yes, what would it cost (depending on whether again tuv is made or not)? 3. if a rep. is not worth it anymore, is it possible to get the old performance again, possibly replace spark plugs or so (it doesn’t make any fun anymore to drive around with it)? thank you for the antw locate in advance!
