The following problem: My Omega always had a few problems in the cold start and this also at about 1500 revolutions. Since he also lost a lot of oil I went to the bottom with my brother yesterday together with the problem with frightening result. The oil loss seems to have been caused by a defective valve cover seal, which did not hold the oil back towards the candle bench. In the following two candles stood completely in the oil. When my brother wanted to screw them out brewc This is how we alarmed a compression pressure measurement with frightening result: seen from the front: cylinder 1: ca 4 bar, cylinder 2: ca 4 bar, cylinder 3: ca 8 bar and cylinder 4: ca 10 bar. After a short crisis consultation we decided to dismantle the cylinder head. About 3-4h later the head was down and you could see the mine. The valves themselves sin d still completely and also not burned in the head, which was my biggest concern. However, the ventli shafts, if one looks into the exhaust channels of cylinder 1-3 white, only cylinder 4 has no such discoloration. The head now goes to a motor repairer of the hardened valve seats installed and the ventlile grinds accordingly. Once I have brought the cylinder head back we come to the next problem: How do we get the cylinder head properly mounted? I definitely need ne oe gaskets for the suction bridge, for the cylinder head, for the exhaust manifold and new standing bolts as well as nuts for suction manifolds and probably also new cylinder head screws. I have already experienced so much. Now, however, a problem comes into play which I could not solve: the suit order (my brother meant with some engines it would be, but did not know if the omega engine was included) of the cylinder head screws and all torques. I hope you can help me. p.s.: I am They could and should have told me that the valve seats have to be made, or at the latest in one of the two inspections the compression can be measured and thus find out that there is something wrong… Well, at least the costs are kept within the frame, the insertion of new valve site incl. grinding of the valves costs about 35 euros per valve, which then for all 8 outlet valves 280 Euro are valid + new seals and screws, for which another approx. 100 Euro have to be planned (or is it useful here to buy a complete Dirchtungssatz for approx. 140 Euro?). Still goes, fortunately I do not need a new Ventlie (I hope, but they still look good from what I can judge).
