Since the engine was changed only 3 weeks ago, I'd check for loose bolts.
The 'clicking' could be anything on a Zetec.
While tapping in the area of the exhaust manifold, check the bolts holding the heat shield on. If one of the four bolts are missing, it will make a clicking sound. ...assuming there is a heat shield there to begin with ;-)
Well, the first week it wasn't so cold, on the original engine was doing the same (to a lesser extent).
When cold (below -5), it really goes at it until warmed up. afterwards it's not worse than any other 10-year old car on the streets.
124,000 KM, around 78k if my conversion is right. Doesn't seem to use oil, level has been the same for a month (1500KM)
No blue smoke or strange smell from the exhaust.
I don't mind if it goes clickety-click when cold (but it makes my car sound like an old beater).
I will have it looked over by the guys who changed it, but I hate leaving the car 50 miles from home for a couple of days (taking the bus to work is 2 hours instead of 30 minutes)
You mean if it sounds like the screwdriver or the hammer?
