could be a sign rocker cover needs to come off and be flushed out so it breathers a bit better?
if no loss of coolant i would worry about head gasket.

Alright, I didn't have time to take off the cover since the car was being used. So I flushed it as a temporary solution. Seems that fixed it. Not coming back for a while.

If it comes back, time to take it off then. I can paint it too whilst its off :cool:

Will post again with pics if its back

Alright. It's starting to come back again. Will open it up somewhere this month. Anyone has any more suggestion where to look more once the rocker cover is off?

Gonna check the breathers first.
