Clean and dry everything as best you can. Then spray powder on everything. Use something like athlete's foot spray so that it will stick to the parts. Start the engine and run it for only a few seconds. Go looking for the place where the powder is stained. Of course the valve covers should be in place when you do this.
Don't be surprised if fuel is shooting from one place to another and fooling you as to its source.
