I took my van there to find out why it wouldn't smog. First they ruled out the electrical for $290, then said they would take off the valve cover for more money and see if it was a valve or cam and fix it. They took some photos, put the cover back on, and decided not to fix it, gave me the unfixed van back, and charged me $930. Now my van still won't smog. I can't register it, and I am out $930. They did offer me a rebuilt engine, for $12,700!
