Check that the valve cover gaskets are leaking. If they are, then replace them.
Also, check where the oil is coming from and replace any seals or gaskets that are
causing smoke to come into the car.

    Along with the valve cover there is a TSB for this car that has an update to the PCV system. It gives you a new way to route the tubes and it also has you enlarge the veht holes in the PCV system. It also comes with a new oil fill tube, you will have to get a new cap for the fill tube though.

SOURCE: Burning oil-no visible leak. Seems

Hi,

For some reason the Live Session froze. Our apologies for any inconvenience. Please find below the last part of my posts in case you were not able to view them.
photo7 says:
what about the piston rings

Benimur says:
that could be checked with a compression tester at your dealer

Benimur says:
so for the moment course of action would include: compression test
dye to determine where the oil went, if no trace found then it could be assumed was burned; change the catalyctic converter, it went as a direct result of oil in the exhaust system

Benimur says:
some remedial/temporary workaround includes installation of an aftermarket oil cooler with its own fan; maintain a lower engine temperature by removing the thermostat (not applicable to cold regions) and wiring the radiator fan to continously work.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: white smoke at startup

Hi michelle,

Smoke signals:

  • White smoke = water vapor
  • Blue smoke = Oil
  • Black smoke = unburnt fuel
If it's only white smoke and it's only on start up (when its cool) its most likely condensation burning off from inside the exhaust pipes, manifold, muffler, etc. If water was in the cylinder(s), on the spark plugs there would be no smoke, exhaust or a running engine.

If oil was leaking into one or more cylinders the smoke would be blue.


There are things you can check for:
  • Is there any loss of power? Does it start and drive normally with no odd sounds or symptoms?
  • Check your coolant level daily (do it safely, never when hot, OK?). Is it dropping?
  • When you check the coolant, do you see any oil mixed in (floating on top)
  • Check your oil level. Is it dropping?
If you answered no to all of these, whats the problem?

As far as your friendly mechanic is concerned:
  • Has a compression test been performed? on each cylinder? What were the results? Get it in writing.
  • Better yet, take it to someone, anyone else for a second opinion. If you have a friend that tinkers with cars, have them perform the same test. see if they match.
  • If you need to bring it to another shop, don't tell them something is wrong. (I'm sure you understand why)
  • A good story is: you can no longer afford it, you are putting it up for sale and to avoid any complications you want to document the engine was recently checked out (specify you want a compression test to be performed as part of this). Since you are trying to get rid of the car, it's less likely a different 'Problem' will appear ;-), Get it? We want straight answers. See what they come up with.
I don't like to speak ill of someone I've never met, but from what you've posted, something smells fishy. You don't replace an engine because of a known blown head gasket. I'm not convinced yet that this is your problem. If it was, I'd be replacing the head gasket, not the engine.

It's unlikely anyone trying to sell you a $7,000.00 engine based on what you've described is looking out for interests other than their own.

Ask around, friends of friends, find someone trustyworthy. Get a second opinion, a third. It's a LOT cheaper than a new (yeah right) engine. Sorry about the sarcasm, but how would you know that it was new?

Please reply to me with a full list of symptoms, the results of your tests and any other details on whatever you may consider pertinent. This will help me help you.

But my most immediate advice is:
  1. Don't buy this engine
  2. If your car is in their shop, get it out, ASAP.
  3. Get a second impartial opinion.
These may be reputable mechanics, but every warning light in my head is screaming RIP OFF!! Don't let it happen!

I sincerely hope this helps you out.

Mike

SOURCE: audi engine oil leak?

Sounds like a leaking valve cover gasket. The parts are around $50 to do both cylinder heads from www.ecstuning.com. It's not a major issue, but it may be a sore point to a potential buyer.

SOURCE: toyota Paseo leaking oil

Do you have any Leaks on the Ground where you Park? If not, You really need to get that Motor Overhauled. Your Motor is Burning the oil Because ther Rings are Worn out in the Motor and the Motor is Detonating the Oil and Burning it. a Rebuild is the Only Solution.

You probably have a bad oil pressure sending unit or a bad connection to it.

A very small amount of oil weeping onto something hot, manifold, turbo etc can give off considerable smell with little smoke. What's the miles?

Worn engine can give pressure in engine forcing oil fumes/vapour out of breathers onto hot surfaces which then enter car ventilation system.

2005 3.5l some times smokes oil then stops


Smoke oil? For what your thinking that is oil? Smoke coming from the tailpipe is not good news, but does not necessarily mean the engine needs rebuilding. First, you need to determine what color of smoke is coming from the tailpipe
* White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.
* Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
* Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm.


If you confirm us that is oil smoke, check and keep in mind that the car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Keep us updated.

Burning smell and smoke coming from hood


you may have an oil leak and the oil is burning off of the hot exhaust or engine youll have to open the hood in order to decipher where the oil is coming from. or if its even oil it could be transmission fluid coolant a number of things youll have to see if you can tell exactly what it is thats leaking but my best guess is its probably oil.if it is oil its more than likely coming from the valve cover. id check there first.

I have a 96 eclipse 2.0 with 150 thousand miles there is blue smoke coming out of the tail pipe smells like chemicals.


Blue Smoke: Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.
How did the engine oil get inside the cylinder in the first place? The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder. I that doesn't work then i would get with a mechanic and have it leak tested for possible piston ring replacement.
