omega 2.0 16 v, ez 10/95, again problems problems problems

hello ! yes, I do again !!! slowly I turn on the bike with my omega………. 4 years ago for 3000 euro bought at a mileage of 145000. meanwhile he has 19900 druaf, rusts without end and has swallowed shon over 3000 euro at repair costs ;-( since about 1 week following problem ( always only in the morning when he starts the first time. he starts immediately, but he stutters as if he only runs on 3 cylinders. moterpower is ok ! after about 50 m The temperature goes up to approx. 105 ° and then falls abruptly from 90 °. 3 days ago I filled up about 1 liter of cool water – he did not beat but the engine room is dry ! in motor oil was also no water ! today the overflow tank has been empty !!! then……….. yes, goes even further…. front axle suggests ! stabies, crossbar, trackbar, damper etc. is all only 25000 km old. but it’s only when you drive straight. in curves it’s quite quiet ! and ……………. sometimes after starting he guesses so funny – like a sewing machine !!! when he was driven about ten km that’s over. have you tips for me ? oh yes, still something. almost everything that moves or so the last 40,000 km was changed !!! it apparently does not take any end !!!
