when my car is running , why does the engine sound like its ticking? it sounds bit like a tractor, ever since the cold weather has turnt up

Could be lots of things in order and assuming it's a petrol engine and noise goes once engine warm.

Sounds as if oil is slow in getting around the engine.

Have you checked engine oil level

When was oil last changed- correct grade

When was oil filter last changed and has oil filter got none return valve.

Partly blocked oil pick up strainer in sump

Worn oil pump

If noise still there once engine is warm then may be a worn camshaft.

Check the above and see if any improvement
