Hello, the valve shaft seals on my B4 are new now, all 8 pieces. They looked not so good after the 18 years. The tackering at the start is definitely gone, I watch the oil consumption again… Now something new: the car “pulls” now significantly better in the lower speed range. Since the exchange it drives like an F1 car / compared to before but also with increased consumption! It is nice on the one hand, but since I have no sponsor this will be expensive! BC says at least 1 l more on 100km and I drive about 60 a day. I know the track and thus also what the BC should display at the moment consumption. Example: Distance 50 km/h Gang 4 2000U before 5.5 l now 6.5l current consumption. That was done: control number belts had to be taken off, is on again. At the beginning the engine did not start at all (like a tractor) so timing belts moved a position. Then he pushed back the mixture, once with a short flame from the gas he. Ignition was set on it, then the engine purred again. So only for me to orientation what is a typical cause here: pulls better, consumption more — what is? Should I take the voltage from the control unit? How must the ignition be corrected so that it is right again? Consumption before: around the 7…7,5 l now almost 9. Addendum: Today we once again had temperatures above 0° and the consumption is right in total again, Temp sensor in the bucket? Greeting olli
