We once had a customer who had had his 16V scirocco stolen but then recovered. He asked us to try to destroy the engine so the car would be a write-off. My service manager told me to dump the oil, run it till it seized. Well i did that, let it idle, went to get a coffee. came back buzzer going lifters getting noisy. stood there waiting for drama....nothing . Stared revving it ,and revving and revving. 20 minutes went by. i asked the manager what he wanted to do. He told me bring a quarter for the phone and go drive it.Went for a drive, for an hour, winding it up to 6500 every shift. Went back, refilled the oil and gave it back to customer. It took about 2 minutes for the lifters to stop clacking. We saw him drive it for another 6 months as if nothing happened.
