993 exhaust smoke

[Muzaa]

I added a litre of oil to my 993 last week and it has been smoking from the exhaust ever since. It did once kick out a clould of smoke one Monday morning after a long Sunday blast, but nothing like this.

Every time i start it i get a degree of smoke, and when i put my foot down yesterday i could see smoke in the rear mirror.

Could this be caused by me over filling with oil (have checked and the dip stick is indicating it has a litle too much in there) or do you think i have a major problem. Otherwise the car is running well.

Too much oil.
The drain for the dry sump tank is on the o/s sill, just before the back wheel arch, a little panel.

VS is right. Once had a pork specialist overfill by much more than this and it was difficult to move in the workshop, too much smoke on start-up you couldn't see your hand in front of your face

Having drained off some liquid gold it was fine.

If it's not terribly overfilled, then the grade of oil can contribute to smoking on 993s... the 0w Mobil 1 stuff is too thin IMO and ends up in the bores... I always got a decent puff of smoke on startup every day when using 0w Mobil 1.

A good 15w full synthetic is much better IMO, and also recommended by opieoilman on the perpetual oil recommendations thread in the Engines forum

My local garage, supposedly OK doing an oil change,
kept filling and filling, all the time checking the dipstick, and puling comical faces at the result,

(engine off needless to say)

I arrive to find steam engine idling on forecourt
great....

Just in case you didn't know, check the oil level with the engine hot and having been ticking over for a couple of minutes (and with the engine running).

The dipstick check is a bit more accurate than the dask gauge.

thanks for the advice. does seem to be over fill. the level is back down to almost normal now and the smoke has gone (well so far). fingers crossed this is not a major engine issue
