1994 Suzuki Vitara V6 H20A Engine smoking intermittently from exhaust

My Suzuki will Intermittently billow large amounts of smoke from the exhaust for a period of time and then for no apparent reason will stop doing it and run for days with no problems. Any suggestions please

    same and seem to have lots of oil in the intake manifold

    I have the same problem in a daihatsu mira, huge smoke for about 45 seconds then nothing for 10 minutes or so. It seems to only happen on the open road,not around town

    Mine too , no compression failure, new valve seals , still smoke in the mornıngs for 5 sec , and normal then , lots of oil in the intake manifold.

    You were so right. the oil is being sucked into the intake manifold via the PCV Valve and hose. I have dis connected the hose and plugged the intake manifold end and the problem has gone. Super cheap have oil catch cans and I am going to instal one of these to llow the re connection of the PCV valve to the intake manifold and am sure that it will collect any oil that enters the line. It may interest you that with the pipe dis connected the pcv valve is not seeping any oil so it must be just the engine vacuum that is drawing the oil in from the tappet covers. Many thanks for all your help and hope the solution will help others with a similar problem on this engine type

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.

    Glad to hear it, Clobby, and thank you for letting me know.

    ... It's the engine vacuum, I'd have thought so but I'm grateful to you for confirming that. I checked before writing my (lengthy, sorry) comment. It seems nothing at all would flow through the PCV channel unless both pipes (one on either side of the throttle body / butterfly) were connected and there's a pressure differential (eg. the throttle's not completely open).

    Thanks also to Yachtaria2 for your advise. The dipstick in the Mazda engine is very difficult to read and I doubt I'd be able to be that precise. I found with my last sort-of Mazda ('90 KF Laser 1.6) engine that any extra oil would burn off and then settle, I can't remember whether or not I've found the same with this one, I think so.

    I find that the hydraulically adjusting lifters get clicky and noisy when there's not enough oil and the engine's cold. The lower the oil, the more seconds it takes to stop (suddenly). I guess I need a flush, they're probably jamming. If there's enough oil they're fine.

    Off topic:

    Interestingly, yesterday my brother suddenly said, out of the blue, (after telling me he'd bashed in the boot of my car while borrowing it) that he was considering replacing his '99 Magna with something like a Sierra but with one of those 2.0L Engines Suzuki make, oblivious to the fact he'd just been driving one.

    Funny the way the world works.

    Nice engine. Mazda's configured with a variable manifold which makes it sometimes push at 5000RPM but overall it's gentle, revs easily, feels like a V6 except when filling it up. I love it and I'd love to see a version of it that isn't transverse - the Suzuki version. It might be smoother still / more symmetrical. My brother said that he found it very relaxing to drive and this is the first manual passenger car he's driven for any period. Pity he drive it backwards into something solid.

I have solved my intermitant smoking problem. If the oil level is reduced to just under full it stops.If it is on the full mark it starts,

My car has white smoke coming from the exhaust

he causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located.

Suzuki Vitara V6, MAF sensor, white smoke.

My first thoughts are that you have a head gasket or intake manifold gasket failure. This is why you have the white smoke. If you run it too long, your catalytic converter will be destroyed. Check for coolant in your oil too.

Blue smoke from exhaust on first start up

Blue smoke come from burning oil.  This means that you have an oil leak somewhere that it is getting burned up and exiting the muffler.  First thing I would do would be to check your engine oil level.  After you are sure that it is good, I would suggest taking the vehicle to a mechanic to have them see if they can find where the leak is.  Let me know if you have any other questions.  Thanks for rating my response and for using FixYa!
