Try this first before having the engine rebuilt.

Go buy a bottle of Lucas engine treatment and add it to the oil, if in a couple hours of driving you do not gain more power, the engine is not running better Ect. then yes you need to have it rebuilt.

But try this first, this stuff im sending you to get is the leading engine treatment in the world.

SOURCE: 1994 Suzuki Vitara V6 H20A Engine smoking intermittently from exhaust

I have a Mazda which in Australia (here) is called a 323 Astina, overseas a 323f, Familia, etc.
It uses a 2.0L Mazda KF Engine very similar to (in fact co-developed with) the Suzuki H20A engine, except designed to be transverse, variable resonance induction and other different tuning inc. 7000 redline, and probably not as reliable as an H20A.
I've had the engine rebuilt because I want to keep this car for a while and it needed it. Oil slipped past the rings which burned out grooves on one of the exhaust valves on Cyl-6 to the point where that cylinder had no compression...
... but I still get smoke occasionally, as you describe yours except not as often nor on the open road at speed. It happened ever since the first time I changed the oil after the rebuild. The tech who rebuilt it used a grade of oil I couldn't find and, liking synthetics, I used a lighter oil.
About the time you were writing your message, I replaced the rubber intake pipe feeding the throttle body and I noticed the inside of the intake manifold lined liberally with oil. The old pipe had oil only at one end.
The pipe I replaced didn't just go from the air mass sensor on the filter box to the throttle body. There was also a large pipe to an air reservoir (a lengthy pipe sealed at one end so that if you open the throttle quickly, you don't have to wait for more air to be filtered before it enters the engine, supposedly) and a tiny pipe to PCV valve.
It's not a long pipe so it's easy to look inside. The reason I'm boring you with all of that detail is because you'll almost certainly have a different one, but this is still most probably something you'll find feeding your intake manifold a supply of oil. The PCV (Positive Crankcase Ventilation) valve runs from one of the rocker covers (not that we have rockers) into a pipe feeding into this intake pipe. It's supposed to **** air in from the intake pipe due to a vacuum created by another pipe connecting from another part of the crankcase to the intake manifold (after the throttle body so it has a lower pressure than the intake pipe) and that might be happening in my engine but oil is, or was before the rebuild, seeping back into the intake pipe.
Being a transverse version of your engine, the PCV valve is on the front bank and the pipe from it to the intake pipe is quite short. The PCV valve is also situated above (if I remember correctly) a cam lobe so at higher revs, the oil gets flicked up into the PCV valve.
... so use an oil which is thicker at high temperature, do a compression test, or as I'm considering, run the pipe from the PCV valve into a canister to catch the oil before feeding the gasses into the intake manifold. That way less of the thinner oil will be burned off and I'll have a better chance at getting away with using it.
I use 15W40 Oil - viscosity of 15 weight (units?) when hot, 40 in Winter (which the W stands for). I should use 20Wxx, perhaps, to burn less oil.
This engine likes thin oil, it just goes on to liking it enough to inhale it. This engine also likes higher revs.
Hope that helps.

SOURCE: Spark plug location

yes the service light can come on because of the spark plugs. the best way to find out what the service light is on for is to go to one of the major auto parts stores and they will check it and tell you what you need for free. cant help you with the location of the plugs because ive never worked on this vehicle before.

SOURCE: Suzuki GV burns oil

valve seals will not cause this kind of oil consumption, a scocred cylinder wall or broken piston ring will, not sure on the head gasket, does it have a combustion gases present in the radiator surge tank or bubbles while running? if not the head gasket is probaly ok.

1991 Honda Accord, 213k, changed oily sparkplugs and now engine blows excessive smoke and oil continuously out the exaust from start up to shut down.


Old spark plugs were likely fouled with oil and not burning fuel (and oil) completely so minimal smoke before change out. New plugs are clean and burning everything in cylinders well including oil (therefore more smoke). If smoke from exhaust is blue, then engine oil is getting into cylinders either through worn out piston rings, or a leaking gasket. If black smoke, then this is a sign of too much fuel getting into cylinders and not all the fuel is getting burnt during combustion (a fuel system problem).

1992 es300 blue smoke from exhaust


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. So best bet is to have a local repair shop inspect for internal oil leakage.

My 97 honda accord is blowing white smoke and running rough then i went to start it now it wont start


Sounds like either a blown motor (rings need replaced) or a bad head gasket or cracked head.
If the rings are bad your car would have felt like it was losing power because the engine will no longer have the same high compression that it's required to turn the wheels. You may have heard your engine knocking or seen a light blue colored smoke coming from your exhaust as a result of your engine burning up oil in the combustion chamber from the rings leaking.
If your head gasket is leaking or your head is cracked you'd likely find milky looking oil when you drain your oil from water/antifreeze being mixed in and noticed a white smoke coming from your exhaust that is actually water vapor coming through the exhaust.
If your car was running rough when you last shut it off try pulling all of your spark plugs and either cleaning them or replacing them all. A bad head gasket or bad rings can both foul spark plugs. A car will run rough with 1 or 2 fouled plugs, but once enough foul it will no longer run at all just sit and crank over. If changing the plugs get's it started for ya, check your tailpipe first for water, if nothing, change your oil. If no signs of water/antifreeze or milky colored oil then it's probably rings.

K my 460 runs like **** its missing and number one plug was black...i changed wires- plugs -and cap and now runs worse and blowing white and blue smoke....whats wrong with it?

Gas in spark plugs


generally speaking it will be oil fowling plugs rather than fuel, but to do it that quickly you should be seeing lots of blue smoke and a sinking oil level. I have seen fuel fowl plugs but generally **** fuel. you should probably check the plugs are the correct ones for the car, all plugs have differing uses and just cause they fit dont make em right. you could also look at the condition of the rest of your ignition system ie condition of leads, coil/coil packs. Another thing you could check it the condition of the throttle body, looking for fuel colouring additive build up, or even wether it is set correctly (obviously a job for diagnostic tool).
