Neil Sandham Posted July 12, 2002 Share Posted July 12, 2002 Folks, As the engine starts up in the morning, just for a couple of seconds I get blue smoke from the exhaust then after that everything is fine. There is no excessive oil consumption and the engine pulls just fine. If I startup it up later in the day (engine probably still warm) then everything is normal. Any ideas ? cheers Neil.

Digsy Posted July 12, 2002 Share Posted July 12, 2002 Are you absolutely certain its smoke and not steam? Quote Link to comment Share on other sites More sharing options...
JohnK Posted July 12, 2002 Share Posted July 12, 2002 Sounds like valve stem oil seals but I dont know if the supes suffer from this. Quote Link to comment Share on other sites More sharing options...
Digsy Posted July 12, 2002 Share Posted July 12, 2002 Wouldn't that give blue smoke on every start up, not just the cold ones? Quote Link to comment Share on other sites More sharing options...
JohnK Posted July 12, 2002 Share Posted July 12, 2002 Nope, mainly cold starts as the oil has had some time to seep down the valve stem, when the engine is hot the valves expand a little and this stops any more oil getting down, unless they are really shot.

Neil Sandham Posted July 12, 2002 Author Share Posted July 12, 2002 definately not steam ! Valve stem seals ties in with my thinking. But wasnt sure if the same theory (ie when cold over night the oil can seep past the seals) also applied to the turob oil seals. cheers Neil.

Terminator Posted July 12, 2002 Share Posted July 12, 2002 My 2l pinto lump has no VSOS, you should see that on start up. Second thoughts that should be - you can't see it on start up. Quote Link to comment Share on other sites More sharing options...

I concur, valve stem seals, almost certainly the exhaust ones. They go first due to them running a LOT hotter than the intake ones. Turbo seals usually only give smoke AFTER the engine is hot, they leak into the exhaust, effectively, and need that region to be mad hot to turn the oil into visible smoke. I usually find a turbo seal problem gives "oilier smelling" smoke than ring problems, the oil in the combustion chamber sees much higher temps than when it just leaks into the manifold. YMMV :-) Quote Link to comment Share on other sites More sharing options...
ststarkie Posted July 17, 2002 Share Posted July 17, 2002 hmmm.If it was the valve stem seals it would smoke when it was started warm or cold wouldnt it.They do go hard and britle.But to state the obvious u said that u were not loosing any oil.Can u get some one else to start it in the morning for u and smell it.U will easy tell if its oil been burned.

It would depend how bad the seals were. If the car is still for some time even with only slightly damaged seald the oil has time to get past. If theseals are buggered then it won't matter how long your engine isstill the oil just runs past the seals. If you have only one or two seals going, you may not get oil burn after every cold start.

Neil Sandham Posted July 17, 2002 Author Share Posted July 17, 2002 But to state the obvious u said that u were not loosing any oil. [/b] The only oil consumption is what I would consider normal ie about half a litre every 5 or 6k miles. The blue smoke in the morning isnt a huge cloud just whispers, but noticeable non the less. I guess its just the symptoms of problems beginning rather than a full blown (pardon the pun) failure. By Supe has done just under 100k miles btw. cheers Neil.

Barry Posted July 17, 2002 Share Posted July 17, 2002 Mine has not used any oil in the 3k miles I've done so far, but I'll be treating it to a new filter and oil change this weekend. Quote Link to comment Share on other sites More sharing options...

Chris W. (or anyone)- if you're still listening in, i've got big oil consumption on my old mk2 Golf. Think it's oil stem seals too. 16yrs old, 114k miles. Question #1 : Is it fine to just leave it, and keep topping up with oil ? Questions #2 : Do those "Stop Smoke" oil additives work ? (asi might need to do something to get it thru the MOT due to smoky exhaust). Questions #3 : Can they fail a car for MOT due to a slightly smoky exhaust ? Or is it only gas emissions that they check for ? sorry for slight hijack. Oil seal related... Quote Link to comment Share on other sites More sharing options...
