Believe it or not, way back in the ’50s, car emissions were reduced by about 90% by the “Positive Crankcase Ventilation Valve,” better known as the PCV valve. (when an engine is running, there is oil blow-by (pressure build-up in the motor). This oil blow-by was vented below the car and into the air. The PCV valve controls this pressure build-up and circulates the oil cloud back into the engine.) We have been working on cleaning the remaining emissions up every since.
Why am I talking about emissions? Today’s cars do not smell bad when running and appear to be safe to run in a closed environment, like our garage attached to our house – No smell – no harm- right? Yes, we have cleaned the tailpipe emissions up considerably, but not good enough. to run inside your garage with the doors closed.
Recently a friend of mine showed up to help his buddy with a project in his home garage. The vehicle had been started and stopped several times, but since today’s cars run so much cleaner, his buddy did not notice the build-up of fumes. My friend came in later and saw his buddy was having a tough time staying awake. At first, he didn’t notice, but soon the effects of the carbon monoxide were affecting him. He recognized what was happening, and they both ended up in the hospital for treatment. His friend stated, “he would not be alive today if he would have been left alone.”
The safety tip here is obvious: open your garage door if you want to run your vehicle before leaving; better yet, park your ride outside. The carbon monoxide gas will enter your home and circulate for a long time, not exactly good for your family.
