I'm busy servicing my patrol 4.8grx. Ive removed the upper collector to access the spark plugs and ive noticed oil in the intake there the collector bolts onto.
I've noticed oil in there... should there be some oil in there or none at all?

If the car is not smoking or using oil I wouldnt be too worried, but it may be caused by an issue with the PCV

While you are there, you may want to remove that butterly in the intake... the little bolt & nut rattles loose over time & can cause major internal engine damage.

Do I totally remove the butterfly or just fasten the bolt and replace the butterfly

We just removed the whole thing on my 4.8, its just there to aid on cold starts.

Okay so the spark plugs have been changed, engine starts easy and revs up normally. No funny sounds but the check engine light has come on. Nothing seems to be out of place. Double checked all plugs and bolts.
Anything I can check or test?
