I was driving down the road and i noticed the car hesitated twice. When i got home the idle was around 1700 and it was blipping a little bit. It didnt fluxate much but a kind of hmming resulted from it. I popped the hood and heat rushed to my face.. It felt abnormaly hot. I noticed excess oil vaper on the Valve cover..

Where do i start? you guys got any ideas?

Its on a b18c5 block and reg b16a head.

The car has a good amount of miles on itThe car still starts and drives, but this has me asking.. How long? I have a feeling its going to break the next time i have to drive.
