Hello,

I recently failed smog cause of high NOX levels so I wanted to clean my EGR and see if it was clogged. I have a 90 SOHC 240sx and have done the usual maintenance and such. I tried to find writeups on diffearnt forums and only found EGR Removal writeups for the DOHC. When I attempted to take the EGR off there are 2 12mm bolts that hold it down, I was only able to remove 1 12mm on the far passenger side but am unable to have an clearance to the 12mm bolt on the other side. Also the EGR pipe bolt I don't see how you can fit a wrench in there to take it off.. I was only able to take the EGR pipe off from the exhaust manifold side. Any help would be much appreciated

thanks,
Kevin
