overheating and reducing oil
check if oil and water are mixing
to rule out not a gasket issue

[behram.ali]

thermostat valve restricts or increases the flow of water according to engine temp
upon removal the water flows un restricted and the engine temp gets below optimum in winters but remains at the half mark in summers
but as hash4u said it is better to consider checking the gasket issue

Temperature not remains in half in summer.temperature remian below means cold

You should ask your mechanic why in the hell he removed the T valve. The engine needs to operatenon an optimum temperature which means that it needs to heat up and T stat valve ensures that engine is warm enough to operate on optimum temp by stopping the free flow of coolant or water in the system. If there is no T stat valve, the engine will stay cool and will not operate as it is designed to hence you will get poor mileage loss in power and eventually your engine will wear out. When there is no T stat valve, the water or coolant will keep the engine cool which creates condensation in the cylinders which mixes water and oil and kills you engine. This is what is happening with your car, it has started to eat oil.

Your car got heat up due an issue with the cooling system. Because the roadside mechanics do not know the actual cause of heat up, they go for an easy solution by removing T valve but it eventually costs the owner of the car.
