wrenching tips

Looking for a small oil leak? Can be very hard to detect it!
I clean everything with brake cleaner, then powder it with talcum powder ( the same thing as for installing tube or the stuff ).
Check it periodically, 10 minutes, half an hour, hour, day. The leak will be visible when the powder starts to get darker. You will see
every small crack, bad weld or bad gasket.

If you want to check your intake manifold/ carb for an air leak, use a water bottle with a small hose. The engine will stall when it sucks the water in. The good thing is, it doesn't burn. i lighted an engine with brake cleaner as i did the same.......
