California has several hundred naturally occurring seeps, found in 28 counties across the state. Much of the petroleum discovered in California during the 19th century was from observations of seeps. The world's largest natural oil seepage is Coal Oil Point in the Santa Barbara Channel, California.
I just bought a 1990 CRX Si. Drove it home with no problems, with the exception of a few misshifts (i'm used to automatics). After I get to my location and try to restart it it wont start and I start smelling what smells an awful lot like burnt off fireworks, or sulfur. Eventually get it started, it runs rough, smoke coming out of pipe seams, exhaust rattling.
Hydrogen sulfide is a flammable, colorless gas that smells like rotten eggs. People usually can smell hydrogen sulfide at low concentrations in air ranging from 0.0005 to 0.3 parts per million (ppm). Hydrogen sulfide can be released into air, water, and soil at places where it is produced or used. 2  It is released primarily as a gas and spreads in the air. 3  It can remain in the air from 1 to 42 days, depending on the season. 4  In air, it can change into sulfur dioxide and sulfates.
