does it seem to be using oil?

is it definately white?

 

usually:

white=steam which can just be moisture produced from combustion which is normal and a lot more obvious in the winter as the car warms up or if there is serious amounts of it, a blown head gasket.

 

bluey white=oil being burned, ususally happens more on startup,under load or on over run, could be worn rings/bores, valve stem seals, head gasket blown to an oilway, over filled oil.

 

black=excess fuel, engine is overfueling due to poor timing, poor mixture set up, dead temp sender, faulty lambda sensor (or a jabba chip :lol: )

I HAVE A 1.8 16V TOO AND MINE SMOKES A BIT ASWELL, i found that it was more obviouse in the summer when it was hot and i was stuck in traffic , anyway the other day i thought i would put a set of new plugs in ,, and on pulling the leads found that the spark plug wells were full of oil , each well had "less oil in" the further away it was from the oil filler cap,, i thought it may have some bearing

The 16v seems to give these symptoms when the valve stem seals need doing.. the gf's C ('93 2.0 16v) does this as well.. (fine on start up, starts smoking on idle when warm, a little when opening it up a bit)

 

gettin them done in the next couple of months..

 

generally the stem seals go at about 100,000-110,000 miles

 

HTH
