I just picked up a real clean 83 accord with 119,000 miles. It was idling rough so I pulled the air filter cover off and found quite a bit of oil in there. I pulled the EGR valve off. its pretty clean and it moves easy when vacume is applied. I dont see any loose hoses anywhere. The car was well cared for so i dont think it is a blowby problem. Anybody have any ideas? Thanks.
It's just kinda normal to find some oil in there. The crankcase breather goes right up behind the air filter. I would just change the air filter and watch it. If you have tons up there, after you clean it out, I might look into it some more, but after 30 years, some oil up there is nothing to worry about.
Its pretty bad. I cleaned it out but it comes back fairly fast. it gets in the carb and causes it to miss. It smokes out of the valve cover with the cap off.
Have you cleaned or replaced the PCV valve? That often helps.
