Re: pajero 1989,too much smoke durong first start
Is it white,black or blue smoke?
If it's the org. engine it will has over 200,000 miles on it. It's normal to has the valve stem seal/oil seal on the head to leak oil into the cyclinder. The smoke you see is the motor oil drop from the seals. It land on the top of the cyclinders and it create black smoke at start up. The inexpensive fix is to start using high mileage oil with seal conditioner. This will help soften the rubber seals and help reduce internal oil leak. The correct fix is to wait until it's time for a head gasket replacement and let the professional to service the head. Complete head service is the only method to stop this internal oil drip problem.
I will monitor the oil and coolant level.
White smoke AFTER warm up is the first sign of blown headgasket.

Where is the white smoke coming from? Under hood? Out tail pipe? If excessive white smoke from tail pipe, suspect a head gasket failure which in turn will fill the cooling system with exhaust pressure forcing the coolant to come out of the reservoir and resulting in an overheating problem
CHECK DIESEL INJECTORS, SEE IF THE EXHAUST SMOKES OR SMELL RICH, LESSEN TO THE EXHAUST OR PUT YOUR HAND ON FRONT OF THE TAIL PIPE, SEE IF IT FEELS EVEN AND SMOOTH OR DO YOU FEEL IS MISSION, COULD BE A CLOGGED INJECTOR, BAD INJECTION PUMP, A BAD FUEL FILTER, LARK OF FUEL,
White SWEET smelling smoke, or white OILY smelling smoke? If it's white thick SWEET smelling smoke, you have a blown head gasket - that's the smell of antifreeze burning in the engine, which it should NEVER do. If it's white OILY smelling smoke (smells a lot like diesel), then you're getting too much fuel into the cylinders.
If it's sweet-smelling smoke (antifreeze), pull the oil dipstick & check the oil level. If the oil level is HIGH and the oil looks like a mocha milkshake, that's absolutely conclusive - that's what happens when antifreeze gets into your oil, and it's nasty corrosive to engine parts.
I'm not at all surprised that the oil light is on if it won't start - you won't get much oil pressure until the engine is running.
SEE WHITE SMOKE YOU HAVE BLOWN HEAD GASKET OR INTAKE MANIFOLD GASKET LEAKING.IF YOU SEE BLUE SMOKE ENGINE BURNING OIL DUE TO WORN VALVE GUIDES AND WORN VALVE SEALS AND WORN PISTON RINGS. CHECK SPARK PLUGS IF THEY OIL SOAKED ENGINE BURNING OIL.
You should start by doing a compression test on the engine. They are loaner tools from autozone. Once you do that, if your compression between cylinders varies ~20psi, there is an internal problem with your engine. Could be worn seals or rings.
