i took my 86 GN to get smogged the other day. In the past i have taken off the K&N filter and put on the stock set up, but i am tired of doing that. so I just took it in like it is. Is it smog legal with the K&N? isnt it better for the car? anyway, I told the guy at the smog place that the original set up is old and broken and he said that it was ok.. but he said it is an automatic fail for having the K&N style breathers on the valve covers. I have one on the oil cap and the pass. side in the front. I can put the oil cap from my ttype on it for the time being, but what do i do about the passenger side breather. All the nationals i have had in the past had the same thing... what is supposed to go there? I hate dealing with smog.. most people think it isnt smog legal cuz its a GM with a turbo...haha.. also... i need to get a correct oil cap.. where can i get one? is there a special part number? it seems every time i get one it never fits... I need to get this car smogged soon so im hoping you guys can help me answer some of these questions. aside from visual it will pass no problem i believe. thanks!
