Mahindra Scorpio S10 Engine Oil Reducing

[Shahching Pange]

Hello guys please help me out, I have no idea where my engine oil is leaking or vanishing. There's no leakage in the chamber or and other part from the outside but my engine oil seems to be getting lesser and leaser. I have already put 11 litres of oil in the past 3-4 months and I have runner 4k kms. Any idea why?

Hi,
No external oil leaks. Must be burning the oil some where. You don't give the mileage. I would check the pcv and complete crankcase ventilation system, including the oil separator if it has one.
Next check the turbo hoses for excess oil (you will ways find some oil between the turbo and engine/intercooler). After those, it gets complicated and expensive. Damaged head gasket or cracked head. Worn piston, rings or cylinder bores.
PCV is the best place to start. Check and clean, or replace.
