Heating Source

As an automotive repair shop we generate a lot of used engine oil, transmission fluid, brake fluid, gear oil, old gasoline and diesel fuel. The best way to dispose of this hazardous waste is to use it as a heating source for the shop. The furnace is a clean burn just one of many available to shop owners for heating the shop. One would think that it would have an oil smell coming out of the exhaust stack, but it doesn't. It burns so clean that there is no smell or smoke. The furnace is equipped with a filtering system that filters the oil before it is burned. As you can see we developed our own per-filtering system to insure our storage tanks do not get contaminated. All the used oil is put in the 55 gallon tank and pumped through the inline filters into the storage tanks. The furnace has been in use for several years and the furnace filter has never required service. The burn chamber requires service once a year. About every two ~ three years a major service is required by the supplier. This has been done once and when the service person came out he said this was the cleanest one he has ever serviced. It pays to go the extra mile with maintaining equipment. 

Engine Oil & Your Engine

ENGINE OIL:   Engine oil is very important to the life span of an engine.   Dirty oil will cause premature wear to the moving parts of the engine.   The illustration above is an engine oil filter that rusted to the point it developed an oil leak.   For and oil filter to rust to this degree it had to have been on the vehicle way to long.   Oil change recommendations very from 3,000 ~ 7,000 miles depending on the source of the recommendation. My advice to anyone interested in keeping an engine in top mechanical condition is to change the oil more frequently.   The additional engine wear caused by dirty oil will shorten the life span of the engine and cause oil consumption and performance loss.

Unmeasured Air Leaks

For automotive technicians the term unmeasured is know as unmetered. Unmetered is not a term recognized by the English language dictionary yet.

Unmetered air leaks are any air entering the engine without being metered by sensors.   The 02 or oxygen sensor will detect the air leak by setting a lean code.  One common leak is the intake manifold to engine mounting gaskets.   Other causes are vacuum hoses, air intake tubing, throttle body shaft wear, PCV system, and cracks in plastic manifolds.   These unmetered air leaks can cause engine performance issues such as rough idle, stumble, and hesitation.

Cabin Air Filter

The cabin air filter is designed to filter the outside air that enters the cabin of the automobile.   The outside air enters through vents usually at the base of the front windshield.   The air conditioning component shown above is the evaporator out of an older vehicle.   This older vehicle was not equipped with a cabin air filter.   As you can see a build up of debris has collected on this unit restricting the transfer of cold air to the cabin.   This debris could consist of bird feathers, weeds, dust, dirt, molds, and more.   The smell of the air passing through this unit may not be pleasant.   The heater control unit on the dash gives you an option to recycle the air that is in the cabin.   By pushing the recycle button to the on position you close a door that shuts off the outside air.
