Milky fluid under air filter near carby Sign In

Hey there,

I've recently done a service on my 1990 MF Barina and there is milky fluid under the air filter, near the carby. Any idea what would be causing this? I've read it may have something to do with oil and water mixing in the engine? Head Gasket?

Any help is appreciated

This car not sold here so can only go by expected basics.
We know it's old enough for almost anything so glance for anything out of place, broken, corroded.

Is this under air filter or in with it? That will matter. Under would more likely be a coolant leak from any source and possibly mixing with just greasy mess which could be oily too and show as milky. That or if a recent very heavy rain, driving in harsh rain might be a one time thing.

Other could be the PCV (positive crankcase ventilation) valve can't overcome the normal blow-by of a running engine anymore frequently if that from plain wear or lack of oil changes on time or another problem but start with easier things first before blaming a head gasket IMO less likely than an intake gasket but don't have a clue of layout of engines for this car. That hose could blow backwards towards air filter housing if that's what you observed and foul air filter also.

Check all hoses and fluid levels for level and any contamination or mixing. Low coolant would not be normal but some oil consumption could be.

If all else fails and car still runs well and no luck have a mechanic take a look in person beats a website every time for things of the sort,
