Engine seized up on my 99 GTI a couple summers back. Decided to break it down and found that the brass rotary gear was stripped and the rotary valve was damaged.
I’ve read that mostly this happens when the valve ingests something. When it seized I had just had the carb rebuilt a month or so before so that is possible but I can’t find anything in crankcase other than the brass shavings. The crank looks good and seemed well lubed. The gear in the oil pump has missing teeth. Could that hard plastic have broken off and caused this?
Any other common causes of this? I’d like to clean the crankcase and put it back together but don’t want to just for this to happen again.
