ok pulled my upper intake off. When i turned it over there are round holes and square holes. The proplem is the square holes on the passenger side are full of oily crap.








what causes this and how do i fix it. here are some pics.

 

Possibly burning some oil on that side of the engine. Why did you take it apart?

 

i am just cleaning it up might powder coat it white

 

So no complaints then? It maybe burning a little oil, nothing to worry about IMO, what kind/grade of oil are you running? I would run synthetic as when I switched to synthetic I now burn no oil as opposed to the 1L between oil changes before (this was on my '88 5.0 with 230k).

 

i have only run synthetic sense i bought it. i have never added a drop between oil changes. but you say its not a huge issue

 

No, I wouldn't worry about it, it could also be a carbon build up which looks somewhat like oil, but either way, it won't hurt anything, intakes usually have some oil or carbon or both, it's perfectly normal.

 

cool thanks
