Re: susuki baleno 4cyl 1.6l blowing smoke
It sounds like a piston oil ring is broken considering the valve stem guides and seals have been done, oil is definately getting into the combustion chamber there are only two places that can happen through the valves or through the rings, black smoke is always too much gas, blue smoke is always to much oil in combustion chamber. Hope this helps even though it's not the best news.

far too much fuel not getting completely burned upon iginition.
That leads on to look at:
-fouled fuel injectors, (clean them - run injector cleaner)
-lack of air to the intake (filter and clear out tubing),
-spark plugs are fouled, (replace them, ensure wires seated correctly on plug)
-ignition power is low or partial, (ignition system module not sending enough electricity to plugs)
-ignition wires are bad, (check/replace)
-ECM is failing or getting bad sensor readings. (shop diagnosis)
-cat convertors have been removed and sensors are at fault
Its a long list -- do the easy stuff yourself, leave hard stuff to a shop diagnosis.
defective catalytic convertor. It may be plugged up.Make sure ALL the exhaust line from intake manifold(at engine block) to final exhaust pipe are not clogged up.You have reverse exhaust pressure going back towards engine manifold.
with the smoke and smell i'd think the catalytic convertor/exhaust system is getting blocked .Get a fuel addative that covers the cat convertor as well as the valves etc , should clean out the system , might have to do two treatments , follow the manufactureres instructions
Catalytic convertor fails due to oil burning, recent head gasket, improper fuel control,but plugging up at 3000 mile misfire surely plug it up when the vehicle is dumping gas in the catalytic, lean misfire ,running very rich due to a coolant temperature.Who is putting this on?I dont know what state you are from,a catalytic should not be installed unless the vehicle is in proper fuel control.and whoever installed this should foot the bill. You need to claim warranty regardless and plus there is a EO# that must match the vehicle.
That would be exactly what I would look for... When the catalytic honeycombs become blocked, it causes a build-up of exhaust pressure... and this restriction in the exhaust will also have a very definite effect on engine performance: The typical symptoms are an engine that initially seems to running okay, but slowly loses power.. in severe cases it will lose power to the point the engine stalls and will not restart until the pressure build up bleeds off.
Good luck with the problem --- it sounds like you are on the right track. And don't forget to rate my advice: your approval is my "paycheck"!
