How did it get in there, and how much are we talking? Did you ingest a bunch of it through an aftermarket air intake? Or were you changing spark plugs in the rain and got a little in that way? The amount that made it in will matter a lot in this case. Water doesn't compress the way a fuel/air charge will, so any signficant amount of water in the engine can cause serious trouble. If it's just a very small amount, don't sweat it - it'll likely burn off during regular combustion.

Exhaust smoke upon cold start up


you don`t say what color the smoke is so this is a basic indicator with different colored smoke.if it is white smoke like you would see from any car started up on a cold day then this is normal for cars as the exhaust is hotter than the ambient air temperature.if it is a thick heavy looking white smoke and has a sweet odour then this can indicate a coolant leak into the combustion chamber after sitting overnight such as a bad head gasket,if it is a blue smoke then this indicates oil leaking into the cylinders past the valve seal or valve guides on a cylinder that is on the intake stroke when the motor was shut off,if it was rings it would show only under acceleration,if it is black smoke this indicates an overly rich fuel mixture.

Lost power and smokes like the dickens


If it's white smoke, the head gasket is blown
If it's blue smoke, major problem, valve and piston and ring job.

1999 mitsubishi montero sport white smoke


the weakest link from water entering engine is intake manifold losing its torque. their are four water ports right next to valve ports. two in front two at rear of intake manifold. they warp fairly easy.so check before re installing

Too much smoke coming from the exhaust


chk your PCV valve. If faulty it will allow oil to be sucked up and burned. Its the critter stuck into the valve cover and has a rubber hose on it. Good

luck, Ned It's an easy fix and inexpensive. So not to panic.

Won't idle properly, smokes, does not shift right


Black smoke is usually too much fuel to the engine. Check main computer that controls fuel injection and timing.
Blue smoke is usually oil getting sucked past worn piston rings or valve seals.
White smoke = water getting into cylinders, bad head or intake manafold gasket, or cracked cylinder head or engine block.

My car is giving of a lot of blue smoke could it be the turbo seals going bad? could it be the valve seals?


Yes it could be your turbo seal (visual inspection),

your valve seals or guides worn (if it is exhaust, it will be mostly during start up, if it is intake, it will just be a minor leak amount of blue smoke at all times)

your piston rings/cylinder walls worn(check for oddly clean spots on the tops of your pistons near the edges, usually only during deceleration),

or a plugged pcv(check for oil in air filter).

Put new timing belt and gaskets in motor .Now it is smoking.


The valves sometimes get loose when the timing belt is broken. But I would look at the timing . It could be slightly out of alignement. Try timing it again being certain both valves are pressed down. The outtake and intake valve for the number one piston at the top. And timing marks in alignment.

Thick blue smoke. no oil leaks new spark plugs and spark plug wires. checked all cylenders cant figure out why its smoking.


Hi! Chris, There are many causes of oil burning or exhaust smoke. There are three different causes of normal oil burning, 1; worn valve guides (smoking during deceleration), 2; worn cylinders and piston rings (smoking during acceleration), 3; split or worn out valve seal, or damaged intake manifold gasket (smoking all the time). Of course there are several variables in this equation. Sometimes coolant can also get into a cylinder and cause a blueish smoke. If you remove the spark plugs and use a pressure pump on the coolant system (radiator), coolant should leak into the intake manifold or cylinder. Coolant leaking into the intake manifold will leak into several cylinder through the valves. So, what year and how many miles are on the Jaguar?
