jamesc 3 Posted June 30, 2006 Doesnt smoke on start up, idle or when being driven (soft or hard) but as you pull off from a junction a puff of smoke comes from the exhaust... cant see it from inside the car but someone following noticed it. What wrong? She's not been used for some time and only done 4/5k in the last 3 years. Still pulls like a train and scares the living daylights out of me!

Cheers My guess is that Your valveseals have hardened. As You stop for the junction You lift off the throttle and by doing so create a vacuum in the manifold. With the engine warm and the oil thin, chances are that a slight amount of oil is sucked into the cilinders along the valve stems of the inlet valves, which creates a nice puff of blue smoke when You apply throttle again.

jamesc 3 Posted June 30, 2006 Thanks for your reply.. Smoke doesnt actually look that blue, initially i thought it was just cold but then after following my mate in it for an hour it still hadnt gone Will it just get worse or by using it will it improve (Yes I am a novice when it come to cars smoking) Also Will it damage the engine further or is it ok to use?

Guest Cartooner Posted June 30, 2006 Sometimes additives in the oil can help for a while, but eventually You will have to renew the seals. It will not damage the engine unless You forget to check the oillevel regulary. It is just annoying and may foul Your sparkplugs and valves sooner. Share this post Link to post Share on other sites
SweetBadger 94 Posted June 30, 2006 (edited) Yep as cartooner says it won't harm your engine as long as you keep an eye on the oil level, however it probably won't do any good for performance. I tried adding some stop-smoke to my old smokey 1.6 (valve stem seals had gone) and it didn't make any difference at all, so I wouldn't bother - its so thick it looks like treacle when you add it so I can't imagine it'd be doing the rest of your engine any good. Mind you, by that time it was just plain embarassing to drive, the smoke was so thick that I couldn't see behind me when I stopped at a red light so it was worth a try!

Sounds like my 1.6 I tried filling up with some 20W50 oil and Wynns Stop Smoke and did bugger all. At least it confirms that <hopefully> my piston rings are ok as I'd have thought anything that gloopy would have not made it past them. Should have the head off soon and will be interesting to see how badly fooked the stem seals are as according to the service history the smoking problem started in 1997 and about 46k miles ago, and has never been tackled in that time Share this post Link to post Share on other sites
Guest Cartooner Posted June 30, 2006 Well, there is a difference between worn valve guides and seals, or like in this case when the guides are probably still ok but the seals have just dried up and lost their flexability. An additive might do the trick by softening the seals. Share this post Link to post Share on other sites
