My Car started overheating and ended up mixing oil with water on the engine , sent it to a mechanic it was a first time sending it to a mechanic , guy fixed it but car came back with rev counter only going up to 4 now , doesn't go pass 4 and when driving it was cutting , car lost power was not using gear 1 for steep road even gear 1 will fail in the middle and ill haave to re put on the gear , drove the car for a day and the car was now needing like 4 liters per day , a week later the car has mixed oil and water again as the original cause was not found, for the rev counter the timing was suspected to be wrong , I took it for timing correcting that guy told me the cylinder head was over skimmed now it a bit thin it need to be filled back to correct size either than that timing cannot be corrected. So now my car has timing fault, taking too much water about 4 litres per day and has mixed water and oil again
