On my 90SC, the drivers side valve cover has a vent type tube that crosses over to the MAF area, My cone air filter had alot of oil crap and looked like now it is coming from this tube from the valve cover , so I took it off and re-ran the tube just to vent out , I do see alot,, just fog type air coming out , is this OK to do or is there something wrong ?? Let me know what ideas you guys may have on this, its a nice built engine , but I do not run it hard at all, has around 20K miles on it . Thanks for any HELP .
