Corsa 1.0 12v -Black Fluid and Vibration - fraz
Hi I have a sub 20k miles 2001 Corsa 1.0 12v.

I have noticed black soot at end of tail pipe, went to wipe if off and black fluid is present inside exhaust. What might this indicate and are there any tests i can do to identify the likley problem.

Also the car vibrates mildly when staionary, i have looked under the bonnet and engine does seem to vibrate abit tho not excessively. Is this normal, anyone else had this, could this indicate a problem?

any advice greatly appreciated.

Does the car do a lot of short journeys? If so "black fluid" is probably just sooty water. Are you loosing water from the radiator at all? Or mayonaise on the dipstick?

Usualy tells you the cat is working fine..most cats will do this when working correctly..I got pulled once in my old 414..It after having short runs developed a lot of water in the exhaust..slight uphill drive and exhaust poured water.ie black sooty..out of rear tailpipe..engine was fine..Doubt you have a problem??

Mild (and I stress mild) vibration is a feature of the 1 litre 12V - it's only got three cylinders after all and isn't as inherently balanced as a four cylinder engine despite the whopping flywheel Vauxhall fit to mask the vibration. I agree soot and liquid is just probably water & soot from cold short journeys mixing in the tail pipe unless other problems are showing up. You may even find a little mayonnaise on the inside of the plastic oil filler cap. My wife's 1 litre (2002) Corsa has had this fom new during the winter unless she gives it a good blast to warm the engine right through. Her car runs beautifully despite its frequent short journeys.
