i have a b16a3 and just today the motor started to idle funny when i am in neutral at a stop. like it feels like it dies then strats back up real quick. so later that day i drove it and it sounded weird, and my valve seals are bad and im blowing alot of smoke. but when i drove it it felt like i lost alot of power and like it was bogging...i got home and seen oil all over cyl 3 header (thats all, no oil on head or block) and when i pulled the spark plug wire out the idle remained, unless i fouled the plug. anyone know whats wrong? its running crappy
