Black Sooty Smoke
 

Taking the car back to Wales tomorrow to re-unite her with her old owner for the day. Ran the usual pre-trip checks today and I noticed she is puffing out bit of black sooty smoke out the exhaust. Anything I should be overly worried about or is it just cos she's a bit choked up with me just running her up in the garage. No signs of oil leaks and it's definately sooty as opposed to the sort of bluey hazy smoke I would associate with her burning oil.

Any advice appreciated.

Hate to say it but maybe she just needs an Italian tune up.

You probably right Matt but she does make me nervous at times. Anyway a good run around the hills and valleys of North Wales will probably do her a world of good. It may be the carb just need a bit of tweaking now the engines settling in after all the recent work. The joys of Audi ownership :crazy:

Webers suck

nothing sucks like an electrolux

Nothing sucks like the ex missis....

Black smokes indicative of rich mixtures martyn, blue smoke -oil and white would be something like antifreeze or autotrans fluid being burnt.

As suggested, needs a good run to get her warmed through nicely and get rid of any buildups of carbon that may be accruing.
Engines never really get hot enough unless theyre being driven with some gusto. :)

well emjay if you coming to wales come by boat leave the car behind m8 the weather is really bad m8, what part of wales do you hope to get to m8

going to Porthmaddog Gabe (hope I spelt that right)

sorry m8 i spoke to my m8 who lives up dollegallu not far from your place check the area before you leave ok do not turn your car into a submarine please its toooooooooooooooooooo nice to do that

I'm sure there's nothing wrong Martyn, she probably just needs a good blast to clean her tubes out. Portmadog's lovely been there lots of times over the years. have a good trip matey :tup:

Hey up Matrtyn. You ought to have called me bud. I would suggest that as stated, it needs a good boot-full or perhaps a re-tweak. Blak smoke is a sign of too much fuel (or too little air - blocked filter etc) so nothing to owrry about. Give me a call if u need to buddy

Hi Ben

she ran fine over the welsh hills so not to worry too much

One thing that I have noticed. Now we have routed the rocker cover breather pipe back into the air filter assembly, the paper filter is starting to get covered in oil vapour. I wonder if this is ulimatley causing a problem with air flow and the mixture as the filter starts to clog up :idea:

Or carb freezing issue. Had this all the time in my 1.9GT with weber carb many years ago as soon as the air temp dropped below 8 degrees and on any trip too. The fact that I had no diverter for the hot air from the exhaust was to blame.
Regards oiled up filter you could fit a catch tank to stop the heavier oil particles, has made a big difference to my car with far less oil coating the inlet pipework.. :tup:

would very much like to see your catch tank install.. do u have pictures? And where did u buy your catch tank from?

(p.s, sorry for the slight thread hi-jack)

cheers.

was just thinking the same thing Gaz :rock:

Made it from some scrap stainless steel tube in our workshop. Undertray is off at present so will whip it off and take some pics. Needs a clean anyway whilst car on SORN.:tup:
Pic is of a similar homemade one I had on the 7A engine (top right).
