Hi,

Friend was driving behind me today and noticed blue smoke comming from the exhaust. It only comes under hard acceleration and I have not noticed it myself before.

What are the common causes for this? Would like to get to the bottom of it before any thing major goes wrong, or do I need start fearing the worst at 111k??

 

Oil being drawn past the control rings on the piston and getting burnt

Damaged PCV valve allowing oil to be drawn from the rocker cover/crank case and into the inlet manifold.

Pull the plugs and check for signs on oil contamination as a first stop, but all <04 engine burn/use oil to some extent, so i wouldn't worry unduly just yet.

 

how much oil do you use?

 

You weren't turning right up an incline at the time were you?

 

And now the end is near and so I face the final curtain etc etc

 

Topped it up a couple of weeks ago, had used no more than usual.

 

ok is that 1ltr every 100 miles or 1000 miles - also do you have a decat?

 

Old person's answer!

 

are you certain it was blue and not black? ....Black smoke is more likely to be overfueling.

 

Check the plugs and the seals round the plug wells on the cam cover. Mine was blue before it went pop
