It is possible that rubber valve cover seals dried out and when engine got hot the seals cracked and that will create oil weepage on to exhaust manifolds , if it runs ok , replace valve cover seals

Sorry, you have damaged your engine. Probably ring damage on one of the pistons.
No smoke from the exhaust? Make sure you check the engine oil regularly. It will be an expensive repair. You must not have had a lot of miles on it huh? I am surprised that the top half didn't give out first, or did you already have a coolant leak somewhere and lost pressure?
Do a compression check on all cylinders and that will tell you which piston is damaged. Good luck.
Please remember to rate this solution.

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.

Filled up with gas started cutting back and smoke from back of engine


not sure what you are describing really, is it possible you can elaborate? After you filled up this happened? The engine started cutting back? Did you put diesel instead of gas? A common mistake! This will make the vehicle putt putt if it even starts and will have no power what-so-ever! Will just sit there and putt putt. A plugged catalytic converter will get red hot and sometimes hiss if there is any leak you your exhaust and the car will overheat and have a loss of power and the hotter it gets the more the power loss will be until it overheats the head and warps it or blows a head-gasket.
If that is smoke from a fuel leak then this is dangerous of explosion.
If you had a service guy check your oil when you filled up, he left the oil filler cap off and it's spraying all over the exhaust and engine and again dangerous of fire. You must carefully determine what is leaking to cause this smoke, it's either an exhaust leak, an antifreeze (coolant) leak or from the power steering or transmission line or brake line. One thing to find a small leak is to place a piece of cardboard under the engine to see what and where anything is dripping.

Seat alhambra leaking oil from exhaust and smoking


The most likely cause is a worn bore and the oil is leaking past the rings. It is possible that the oil is entering the combustion chamber through a breather.

Possibility of a cracked block. how can i be sure/


Vehicles: Any with the above symptoms

A cracked cylinder block will cause either:
(a) motor oil contamination of engine coolant
(b) coolant contamination of motor oil
(c) white exhaust smoke, due to coolant seeping into one or more cylinders.
(d) more than one of the above
(e) all of the above

Oil infiltrating into coolant is easy to see - drain some coolant out through the pepcock at the bottom of the radiator, and place it into a styrofoam coffee cup. Oil droplets floating on top of the green (or orange) coolant are easily seen. Or visualize oil by looking into the top of the radiator through the radiator cap.
Coolant infiltrating into and mixing with motor oil will permanently damage the engine (seizing it up through loss of lubrication), and must be prevented.
A leak from above the front suspension is, as physicians like to put it, "nonspecific", with the most likely cause a water pump seal or hose/hose connection.
A leak from near the fire wall will usually be a heater core hose, or hose connection.
A coolant leak on the same side of the engine as the water pump is a leaking water pump or water pump seal until proven otherwise.

To rule out everythng else, here's the 1999 Honda CR-V Troubleshooting Guide for Coolant Loss/Coolant Leaking:

Priority Action Part Type Cause
1 Inspect Water Pump - Worn, Cracked or Leaking Water Pump, or Water Pump gasket.
2 Inspect Head Gasket - Leaking Head Gasket.
3 Inspect Radiator - Leaking Radiator Hose(s).
4 Inspect Radiator Cap - Worn or Damaged Radiator Cap.
5 Inspect Radiator Hose - Ruptured, Cracked or Leaking Radiator Hose.
6 Inspect Freeze Plug - Leaking Freeze Plug(s).
7 Inspect Intake Manifold Gasket - Leaking, Worn, or Damaged Intake Manifold Gasket.
8 Inspect Water Outlet - Cracked, Leaking or Damaged Water Outlet.
9 Inspect Heater Control Valve - Leaking or Faulty Heater Control Valve.
10 Inspect Radiator Drain Pepcock - Loose, Damaged, or Faulty Radiator Drain Pepcock, or Pepcock O-ring.
11 Inspect Engine (DOMESTIC ONLY) - Cracked Cylinder Block Leaking Coolant into at least one Cylinder, causing white exhaust smoke.

My toyota vienta 3VZ-FE 1996 - oil leak onto exhaust


Hi,

That engine will leak oil from

- cam cover gaskets (rear one drips on the exhaust)
- camshaft end seals
- distributor shaft o-ring (appears on top of transaxle housing)
- oil filter bracket to block o-ring seal (drips on front bank exhaust)
- crankshaft nose oil seal (have done with timing belt change)
- rear main seal (expensive, leave it be)

Loud hissing noise on 02 wrx under acceleration. Boost gauge showing the correct boost level but no power though.

Exhaust leak and oil loss


the valve seals leaking oil inside the cylinder will cause an internal oil leak you can't see. exhaust leak is something different. best of luck.

Smoking wrx


Hi , I`m not sure about the 01 model but the 98 model got this roker cover gasket problem because it`s too close to the exhaust and with time can`t handle the heat.So when you rev the car , dropping oil on to the exhaust and one little drop of oil can make big smoke which coming up around the turbo. Hope this helps .
