Zetec Smoke and power loss?
Aswell as the leaks and breather spitting oil, the 2.0 Zetec in our Fiesta tends to smoke under high load. Over the past couple of days, in 4th gear
high rpm the car produces a cloud of smoke and sometimes hesitation/loss of power. First it happened in 3rd gear, then moved on to 4th and now doing
it in 5th. It doesn't seem to do it (even on limiter) in 1st or 2nd. There is no fouling of the spark plugs, the smoke is grey ish, no mayo on
filler etc. When it first did this, the exhaust started popping and banging. The engine is cammed, is there a chance the cat is on it's way out?
I know oil is leaking onto exhaust and burning, it doesn't smoke on start up and only smokes when driven hard briefly. I'm having a
compression test done tomorrow, is there a chance the PCV is blocked? Asked a similar question the other day with regards to the cam cover breather
leaking/gurgling and I'm wondering if this is all linked?
