my engine has a knock coming from what sounds like bottom left cylinder. its constaint with the rpms, but quites down at about 3000 rpms. my water pump line was clogged and wasent spitting, so i took it home hooked up the hose and unclogged it. next time out is when this all happend. i would like to do as much as possible before having to take it in to a tech. any suggestions would be much appreciated.

Noise has a habit of travelling. I'd suggest taking it to a tech who can follow the sound before saying last rites.

A compression test woud be a first step.
