My fiesta (X Reg, 1.25, 16v etc etc etc) is not running as it should be. I had the head-gasket fixed a number of months ago and ever since then it has never ran the same. I understand that this is normally the case for any car - that is to say, once the head is sorted the car is never really the same again. However, these are the problems with it at the minute:
1. The car seems to be "pinking"; I have tried using injectorCleaner in the tank and that has done nothing. Basically, when hitting the accelerator, there is a horrible clunking noise (rattling) I hear and simultaneously white smoke coming from the exhaust; now I am aware that the exaggerated release of white smoke from the exhaust tends to be a symptom of Coolant leaking through somewhere - however - it seems as though this cannot be the case because the Coolant levels have not dropped at all since the head gasket was sorted. So where this white smoke is coming from is beyond me. Also, where/why this rattling noise exists is beyond me.
2. The car is using up a lot of oil. In about 2-3 weeks it used up a "MAX" level of oil.
Could this really just be pinking?
Is the car even pinking at all?
What could this all be?
Have you completed a compression test.
Have a simuler problem with my 1300 fiesta and after doing a complete head recon and found nothing amiss .I have low compression on No.4 and have concluded that I have either worn bore or maybe broke rings. The Oil useage would tend to indicate this.
