Smoking exhaust also
I hardly use my 945 tic nowdays,recently head clutch replaced,brake abs sensor,just about to do yearly oil change,brakes grease etc.Great car very strong and simple to work on.My exhaust permenantley black/sooty.Leaves a mist smoke on acceleration I am not sure if turbo bearings letting by a bit,plenty of power still when turbo spools up,maybe valve stem seals.I have fuel cleaner to fill new fuel filter and try at service and 10w60 fully synthetic oil to try.I will be very interested if you can get the correct vacuum pump and it works.I would think a new pushrod bit would be needed also?I am debating how much to spend on my car with 197000 miles as vacuum pump and turbo not cheap.I do not know how original injectors still going too.Have read people take apart pump to clean with bit of success.I believe it is broken spring/worn connecting rod which makes the noise.Camshaft snapping is end result so rocker cover off to check pump lobe?
