RedM Posted July 9, 2007 Share Posted July 9, 2007 Twice today I've noticed a puff of smoke (white/grey) from the exhaust. First time I'd been pootling along behind a car and the smoke happened as I pulled out of a junction. The car wasn't under hard acceleration. Second time I was pootling through a camera heavy 30mph section and as I gave a little bit of extra gas it puffed again. Thoughts? Quote Link to comment Share on other sites More sharing options...
Jezz Posted July 9, 2007 Share Posted July 9, 2007 Stem seals at a guess. Mine did the same, but more on first start up of the day than when actually driving. Quote Link to comment Share on other sites More sharing options...

RedM Posted July 9, 2007 Author Share Posted July 9, 2007 I went out for a drive this evening. No matter what I did I couldn't get it to smoke. Fast, slow, heavy and light acceleration. Not a puff. Quote Link to comment Share on other sites More sharing options...

Best time to check Martin is first thing in the morning. If it lets out a white/blue puff on start up after standing over night, then it clears after 5-10 seconds, its almost certainly weepy stem seals.

Not a puff. try driving in a low gear highish rev range, then let off the throttle and let the engine overun for a bit, then slowly throttle on and see if you get smoke Quote Link to comment Share on other sites More sharing options...

Never had smoke after the first few minutes though. Could it be that as I was pootling along using OD Off to slow the car it could have caused a build up of gases that were then released when I pulled away?

Guest gzaerojon Posted July 9, 2007 Share Posted July 9, 2007 Pfft, you and your auto boxes of cleverness, what will they think of next driving with the engine in over run puts more load on the turbo seals, this was how i could simulate mine hope it's not turbo seals though Quote Link to comment Share on other sites More sharing options...
Homer Posted July 10, 2007 Share Posted July 10, 2007 If it's not putting out a puff of grey/blue smoke on a cold start I can't see how it's the stem seals. Maybe get someone else to start it after it's been stood for a day or two while you look at the exhaust. Was it a cold day or was the engine cold? If not then that should rule out condensation. Smoke on a properly warmed up engine and applying a bit of throttle could be an easy sign of ring or turbo seal problem. Can you get anyone else to drive it, while you follow behind and see if there's any smoke one when giving it a bit of throttle (need not be a lot). Also, after it's been out for a good run, can you leave it idling for 10 minutes or so and see if there's any smoke after a blip of the throttle.

RedM Posted July 10, 2007 Author Share Posted July 10, 2007 Homey, As I have mentioned: Yes, I do get a puff on start-up. I know my seals need doing. The smoke I saw was from quick blips after pootling along. I was rolling in third with OD off so as to allow some pretend engine braking. I took her for a drive tonight and could not get it to smoke at all. No matter what I did! I've left the car idling and no smoke bar a few wisps after several minutes. As a thought, I had an oil change on Friday. Could it be a little over-filled. Quote Link to comment Share on other sites More sharing options...
Homer Posted July 10, 2007 Share Posted July 10, 2007 That'll teach me for not reading the whole thread! Stem seal issue confirmed then, but thats not serious by any means. It's the smoking after it's warm that would be the concern. A little extra oil may contribute to this, but IME unless it seriously overfilled I can't see it causing too much smoke. What boost levels are you using? Quote Link to comment Share on other sites More sharing options...

Homer Posted July 10, 2007 Share Posted July 10, 2007 So probably pretty much stock boost. I'd certainly go with the tests suggested eariler, i.e follow the car after it's been idling for a while and see if it blows any smoke when the engine is under load; and again when hard throttle is applied. If it's not smoking out the exhaust then it's not so likely to be a turbo seal or ring issue. If you want to check for ring issues get a leakdown test done (should only take an hour at a garage that knows what they're doing). This will at least confirm if there is a ring issue. It *may* also be a gearbox or FMS leakage issue whereby the oil is getting onto the exhuast. I've seen this before a few times but it can be easily checked for.

simonas Posted July 10, 2007 Share Posted July 10, 2007 mine did this recently and as it gradually got worse the smoke became more frequent. It still pulled the same and I discovered it was cracked turbo housings Quote Link to comment Share on other sites More sharing options...
Thorin Posted July 10, 2007 Share Posted July 10, 2007 Twice today I've noticed a puff of smoke (white/grey) from the exhaust. Relax, it's only illegal if it's a company vehicle and there are other people that use it. Quote Link to comment Share on other sites More sharing options...

RedM Posted July 10, 2007 Author Share Posted July 10, 2007 We think we know what it is, and by we, I mean RobSheffield and me. I had Rob follow me and we went down some long hills with the car on over-run. At the bottom I booted it and got a puff of smoke each time. Only happens after long periods of over-run (ties in nicely with the events of yesterday) which is good as in not really bad. Rob said something about vacuums and seals and then I had to lay down as it's all lost on me! Cheers Rob. Quote Link to comment Share on other sites More sharing options...
