earlier today i had an intake leak so i decide to put on sum new gaskets. After i change them off i took the car for a spin around the block when i noticed white smoke. When i got home i checked the oil dipstick and it wasnt milky(looking for heads leak), so i pulled the valve cover off and notice coolant in there. could this have happen earlier when i had that intake manifold leak? and should i go ahead and perform an oil change on it also.
