I have a Chevy S10 with 165,000 miles 2.2L 4cyl. The truck drives great but it is not passing smog. I placed a new catalytic converter on it 2 years ago at 110K and it passed afterward. Now it wont pass again. I want to change the PCV and O2 sensor but can not locate them . I have a repair manual but even that does not give an accurate description of the location. When taking of the intake box to expose the valve cover we noticed there is oil in the intake box which could contribute to the poor emissions. And we thought the pcv was on the valve cover but were not sure enough, because it wasnt easy to move it, so we left in place til I could get more expert advice. I really need help and am more than willing to give a donation for the site. Please help somebody!!!
