147 sky high oil usage
Got a list of problems with the car as long as my arm but I'll try and list as many of the symptoms as possible.
It's a 147 02 plate 2.0 TS and has been a lovely car for a while but now the problems are getting a bit more serious!
The coolant expansion tank is full of oil emulsion. Had a sniffer test done but it didn't change colour. Garage suspected head gasket or oil cooler to be at fault but said it wasn't worth repairing due to value of car.
It's using max to min worth of oil per 2 weeks (2-300 miles) but the coolant tank level doesn't increase which, coupled with no oil puddles on the floor lead me to think it is being burnt? Is this related to the oil in coolant issue or is this separate? There is no oil round the exhaust tip, only carbon, and there is no noticeable smoke when starting, driving or revving high which confused me!
Along with the above issues it also has the MCSF warning which I have read is commonly a crank sensor however this was replaced ~18 months ago. There is no power loss or any other noticeable problem associated with the warning light. Same garage as did the sniffer read the error codes and mentioned something about oxygen sensor/ lambda sensor but again claimed it wasn't worth doing. They cleared the errors and it didn't reappear for 3-4 days of driving.
Any help/ advice would be gratefully received
EDIT: forgot to mention, it has never overheated and actually can't get to temperature sometimes (when driving on cold days or even quite fast it dips below 90 maybe 5mm or so). This I guess is the thermostat being knackered but possibly this is also due to the oil based coolant its using at the moment?!
