Hello, I asked you a question. I had my GM smallbblock completely renewed. changed after about 400 miles of oil. before the week there was also enough oil in it, but I had already discovered oil sludge – which I didn’t think was bad, because it can be created by short distance trips – at least I looked again after the oil and had to find out that the oil level was under the minimum and white sludge was on the measuring rod. oil loss I didn’t have any more, that’s relatively safe. what now? oil refill? new oil change? besides, today for the first time a red light on the rotary meter has lit (in accelerating) what does the questions say? questions about questions may help me. thank you in advance.
