99 Honda accord engine smoking when on?

I can't diagnose your car problem remotely, but I can give you some general pointers on why your 1999 Honda Accord might be smoking when running:

Possible Causes of Engine Smoke:

* Burning Oil:

* Worn piston rings: This allows oil to seep past the rings into the combustion chamber, where it burns and creates blue-ish smoke.

* Valve stem seals: These seals can become worn or damaged, allowing oil to leak into the combustion chamber.

* Oil pan gasket: A leaking oil pan gasket can lead to oil dripping onto the exhaust manifold, causing smoke.

* Burning Coolant:

* Head gasket failure: A blown head gasket allows coolant to mix with combustion, producing white smoke.

* Cracked cylinder head: A cracked cylinder head can also allow coolant into the combustion chamber.

* Burning Fuel:

* Fuel injector problem: A faulty injector can leak fuel, leading to excessive fuel in the cylinders, causing black smoke.

* Other Causes:

* Overheating: If the engine overheats, it can cause steam from the coolant, appearing as white smoke.

* Oil filter issue: A clogged or damaged oil filter can cause increased oil consumption.

* Exhaust leak: A leak in the exhaust system can cause smoke to appear from the exhaust.

What to Do:

1. Inspect the Smoke:

* Color: Blue smoke is usually oil, white smoke is often coolant, and black smoke points to fuel issues.

* Quantity: A puff of smoke is less concerning than a continuous stream.

2. Check Oil and Coolant Levels:

* Make sure your oil and coolant are at the correct levels.

3. Check for Leaks: Look for signs of leaks around the engine, especially near the oil pan, valve cover, and head gasket area.

4. Contact a Mechanic: If you can't identify the cause of the smoking, or it's a significant problem, get your car checked by a qualified mechanic.

Important Notes:

* Safety: If you notice significant smoke or any other unusual behavior, stop driving immediately and have the car inspected.

* Diagnosis: A mechanic can use diagnostic tools to determine the exact cause of the smoking and recommend the appropriate repair.

* Maintenance: Regular maintenance, including oil changes, can help prevent some of these issues.

I hope this helps!
