Found this little trick the other day and decided to try it out. My sons 7 had developed an exhaust leak that I could not find. So I jacked the car up on all four corners and duct taped the leaf blower to one of the exhaust pipes and blocked the other with duct tape. Turned on the leaf blower and using soapy water in a spray bottle started spraying all of the joints, pipes etc. Low and behold I found that one of the muffler gaskets had failed. Big bubbles started developing around the leak. Changed out the gasket and leak is now repaired. Wonder if this would reveal a leak in a head gasket?
Was so surprised with the results I tried it on my 95 Honda Accord that for years I knew had a leak but could not find it. Well finally found it. It was a leak on the exhaust manifold. PO had snapped off a manifold nut and there was nothing applying pressure on this end of the exhaust manifold. It was hidden by the heat shield. Still waiting to get the parts for this repair.
When you make up you soapy water use liquid dish soap and don't be shy about the amount. The more you use the bigger the bubbles :)
