Fumes inside Car

[gapv7777]

There's a certain odor inside my car ( smells like grease) during sudden accelerations. I had the exhaust checked and it looks ok naman, no leaks or whatsoever.

what do you think is causing this? will undercoating resolve this?
what about the airconditioning system? do I need to have this checked as well?

My car is a '94 nissan sentra, btw.

thanks.

check mo muna aircon vent mo(the opening that gets air outside)...minsan worn out na yung rubber nito....

Baka may oil leak sa engine compartment which gets burned whenever the engine heats up. Kaya amoy mo yung vapor.

thanks for the immediate inputs. more questions....

A/C sucks air at the grilles at the base of the winshield where the wiper parks.

Check your engine compartment firewall (the partition between engine compartment and passenger compartment). Baka punit or missing na ang ibang rubber plugs/grommets.
