Question about Ford Expedition

1 Answer

I have a 2000 expedition. I have a misfire but it is being caused by oil in the plug well. OIl burns off the exhaust manifold when I drive it and it gets into the plug well. My question is what the heck is leaking that will allow oil to get to these two places?

SOURCE: exhaust manifold has a leak planning on drive

All possible damage to your car aside, you could potentially fill the car with exhaust gas. Best case you'll get woozy or a headache. Worst case you could pass out while driving. It is not a good idea.

Is it bad to drive my 2006 Malibu with blue smoke from tailpipe

That could be a sign of a blown head gasket check and make sure the car is not over heating if so that may be the case.

Why is my 2000 kia sephia blowing blue smoke from the tailpipe. it has 86,000 miles. the check oil warning light is on even though the dipstick reads full.

The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.

Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.

Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

What cause the 2000 expedition to run ruff and hesitate on acceleration

There are many things that can cause this. It could be a stretched or jumped timing chain, low fuel pressure, a bad TP sensor, a faulty MAP sensor, a bad MAF sensor, intake manifold gasket, internal engine damage, or a clogged catalytic converter. I would start with checking compression to rule out internal engine problems. If compression is good on all cylinders next check fuel pressure. If these 2 areas are ok, perform a backpressure test to rule out a restricted exhaust.

Burning smell

Check the valve covers for small leaks, the oil will run down onto the exhaust manifold and this causes the burning smell. Oil leaks on this model and engine is a very common issue.

2001 deville cylinder misfire 4

the problem is the injector or injector wiring
oil can only get to the cylinder via the inlet and that will burn off or foul that plug
MAF/VAF will cause misfiring
the oxygen sensors to replace are the heated oxygen sensors in the exhaust manifold before the cat converter not the ones after the converters

1992 es300 blue smoke from exhaust

The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. So best bet is to have a local repair shop inspect for internal oil leakage.

In my 2000 expedition, there is a clicking noise on driver's side, at idle but worse when in gear. WHen I put a stethoscope on it the noise is loudest when i touch the exhaust manifold. Also noise is...

The egr vavle could be on the verge of freezing up. When it does the check engine light will come on. However, I think it may be a sticky valve or lifter. Try changing the oil and replacing one quart of oil with one quart of Marvel Mystery oil. This will help lubricate better. I do this in my 2000 Expedition and have never had any problems with it. CD2 is a product designed for sticking valves and lifters if you would rather go that route. I have used it too on an old mustang but not in my expedition.
