Frequently Asked Questions
Where do Mercedes engines usually leak oil?
Most common are the valve cover gasket, the plastic oil filter housing on M274/M264, the rear main seal, turbo oil lines and the sump gasket. We trace the exact spot with UV dye before repairing.
Is the oil filter housing leak serious?
The M274/M264 plastic oil filter housing sits near the exhaust and can crack, leaking oil onto hot components — a fire risk if ignored. We fit the updated housing and new O-rings.
How do you find the exact leak?
We add UV fluorescent dye to the oil, run the engine, then inspect under UV light. This pinpoints the true source instead of guessing from where oil has spread.
Do I need to remove the gearbox for a rear main seal?
Yes, the rear main seal sits between the engine and transmission, so the gearbox must come out. It is labour-intensive but a permanent fix when done with genuine seals.
Why does my gasket keep leaking after replacement?
Often the real cause is high crankcase pressure from a failed PCV/breather pushing oil past gaskets. We diagnose crankcase pressure so the repair lasts.
What warranty do you give on oil leak repair?
All oil leak repairs carry a 1-year warranty on parts and labour, and we re-inspect for dryness after a road test before handover.
Customer Reviews
There was a strong burning oil smell and drips in my parking spot. They traced it with UV dye to a cracked oil filter housing, fitted the updated part and it's bone dry now. Very thorough team in Miyapur.
Oil was leaking near the gearbox. Turned out to be the rear main seal. They dropped the gearbox, replaced the seal with genuine parts and refilled everything. No more spots. Fair pricing near Secunderabad.
Valve cover gasket was seeping onto the exhaust. They replaced it with the updated gasket and checked the PCV too. Clean job and explained everything. Trustworthy workshop in Dilsukhnagar.
