Hello you out there, I discovered a piece of cream before the kuzem. Sierra 2.0i, 120 HP, Built 03/89, 114.000 km and no rust. SOLD! First work: valve cover seal replaced, new spark plugs in, all plugs down and clean, poti lubricate, and some other parts in the area of air intake cleaned. Problem since the beginning also before the work: No matter what engine temperature; in the 1,2,3,4,5 gear I hop like a rabbit in the lower speed range through our S pielstraße (no fear, tried in 4 and 5 gears somewhere else). Presumably, and forgives me my ignorance, in thrust mode, so no gas. And if I had my hoppers, but then right. It was even so bad, that when switching (2, 4,500 rpm, in the 3rd gear) when overtaking would have almost thundered with my bulb against the windshield. SOLUTION? The clutch is quite up, does not mean clean anymore, gears sometimes go (really only sometimes, 1st and Rw-Gang) Can it be that these little cockroach springs, which hold the discs in their position, are sucked out so that, for example, with load changes (also with the clutch), the discs cannot hold properly and accordingly a fake clutch attempt is made. Or did a Grimms fairy tale tie up to me? Since I drove an old Opel before, I am not familiar with the matter of the rear drive and especially not with the machine and its peculiarities. Thank you for your answer. Incidentally, acorn can still turn on the car tax, I don’t give the Sierra back!
