Excessive Smoke from Engine Exhaust Tailpipe
A small amount of smoke from the
of the car is normal. Excessive smoke is created by a malfunction.
The smoke is cause by excessive fuel
or engine oil
. If this condition
is allowed to continue it can affect the exhaust system. Failures can range from
catalytic converter becoming
to engine overheating
and poor fuel economy
we have listed the most common causes for this condition. Many people consider
from a vehicle
to be elusive. Blue smoke is generally caused because of several specific conditions
in the vehicle's engine.
We will help you determine what the problem is so it can
be corrected and stop the blue smoke. This smoke appears mostly at morning start
up because oil from the vehicle's engine is mixing with the gas inside the engine's
combustion chambers, then burned together with the fuel from the
while the engine is
running. This can result in a very expensive repair, but not always. The more expensive
and usually terminal reason for blue smoke is the piston rings have worn out allowing
engine oil to pass into the combustion chamber.Smoke that is Produced by Engine Malfunctions

In this case the engine is worn out and needs to be replaced, this can be expensive.
There are other reasons the engine can
, some engines have
a small oil drain back holes in the cylinder heads, these holes allow the engine
oil to drain back into the oil pan. The oil is picked up by the oil pump and returned
back to the engines vital parts under pressure. If these drain back holes become
plugged it can cause oil to seep down into the valves and into the combustion chamber.
To repair this problem remove the valve cover and clean debris from the drain back
holes, reassemble and recheck (note: after repair you must wait 2 to 4 days before
the remainder of oil on the valve stems to be removed).Most of the time producing
blue smoke can be repeated since it's not usually a problem that is a single occurrence.
Typically, once a vehicle starts producing blue smoke this pattern will continue
to repeat until the engine is repaired. There are times when some engine additives
can cause the blue smoke as well. If you are continuously adding additives
to your fuel to stop smoke, you may be inadvertently covering up the smoke that
your vehicle produces normally. However, if you are continuously adding engine
or fuel line cleaners that are a strange color it can on occasion produce the strange
colors of smoke. This condition is normal and will subside when the cleaner has
run its course.Common Problems and Solutions
The most common problems of blue smoke revolve around oil leaking into the engine's
combustion chambers and burning with the fuel as discussed. However, the solutions
to the problem often vary depending on the exact condition of the engine.
There are times when the correction can be as simple as changing the valve stem
seals or cleaning drain back holes. It is important to note that if you decide to
repair the engine you have, you are often
looking at hourly repair rates plus parts and machine work to repair the engine.
This is quite costly and depending on the age of the engine may well not be worth
the expense of the repair. If you are highly fond of the vehicle and intend
to keep it there are definitely times when a new or rebuilt engine is a better deal.
Keep in mind, if you decide to change out the engine you are often able to extend
the life of your vehicle by 10 years or more which can save thousands over the price
of buying a new vehicle. Plus, your best bet on a new or rebuilt engine can be obtained
by the dealer; surprisingly the dealer cost for the
is close to what you will
pay to have the engine rebuilt independently.If further assistance is needed, our certified car repair technicians are ready
