   Blocked PCV is the course of that.

   Positive crankcase ventilation, its your oil breather system. People refer to an engine "breathing heavily" if the PCV is blocked, i assume that is what you ment by your post. If thats the case, it just needs cleaning out.

   there is no breather valve on a saxo ,so if you havean after market air filter with seperate breather filter and its coming from there ,then check your oil consumption
   any less than 1000 mile per litre and its time to look for another engien
   rebuilding it will cost you alot more .so unless you are fitting forged pistons etc ---find a good s/h unit is best advice
   cost of std pistons from citroen ,and thats only place you will get them is over £400 per set,then add a rebore £150,then all gaskets etc --not worth it for a std engine
