Passing Emissions
I've heard old timers always say to change the oil before. I've also heard
that air filters are removed to help pass. Can anyone tell me if it makes a difference and why? -- Mel P. 77 Bug & 70 KG Cabrio PARTS FOR SALE: http://www.geocities.com/mpernice/VWPARTS/index.htm |

I've heard that you must replace the spark plugs to pass. Here, our cars are too old to be required to even test. We just drive them less to balance out the pollution. or bike. -- Hint; Enjoy the moment ! |

I heard it was because unburned fuel can contaminate the engine oil, and with worn valve guides and rings the contaminated oil can be drawn into the crankcase, raising the emission levels. If you have to remove the air filter to pass I think you probably need a new air filter. A clogged air filter would do the same thing as a choke that didn't open properly. Chris |
