SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

sounds like you left something out. check to see if you plugged in all the sensors and plugs, then check for any vacuum lines that were not replaced or may have been broken

SOURCE: Lexus ES300 White smoke out the exhaust no milky substance in oil

It could be the intake gaskets or even still the head gasket. How about the coolant ? Did you refill with same type coolant ? Have you noticed if it's thick and gooey ? mixing coolants will sometimes produce a thick gooey coolant that clogs up the cooling system. If the car ran hot it could also be a cracked head or block. Warped heads also. Somehow the coolant seems to be getting into the cylinder(s).

SOURCE: white, blue smoke from exhaust

sorry to spoil your day but white exhaust indicates that you have a blown head gasket or the head and/or the block is cracked

SOURCE: Engine oil get less every two weeks in my pajero 4m40

Diesels do lose a little oil out the blow-by tube. If the engine temp. is higher then normal then you will lose more then normal amounts. If you are not leaking it then you are burning it, Possibly worn rings, head-gasket, or oil leak inside turbo. 68 MPH and higher doesn't sound unusual, is the engine still stock?

I'm looking to purchase a used car. I've been doing online research and saw this webpage http://www.usedcarsmells.com . They talk about exhaust color and smells. Is it true that you could tell a lot about...


Yes this is correct, you can get important information from the colour of smoke from the exhaust:

Blue/Gray Smoke: Blue/gray exhaust smoke is an indication of oil burning in the combustion chamber. These are possible symptoms and causes:
Valve Seals: Leaking valve seals will cause blue/gray smoke at startup because oil leaks past the seals into the cylinder after the engine shuts down.
Valve Guides: Excessive clearance between the valve stem and the valve guide allows oil to leak past the gap into the cylinder.
Piston Rings: Worn or damaged piston rings will cause blow-by resulting in blue/gray smoke.
Worn Cylinder Walls: Worn cylinder walls cause blow-by resulting in blue/gray smoke.
PCV System: A stuck closed PCV valve will cause excessive crankcase pressure resulting in blue/gray smoke.
Black Smoke: Black exhaust smoke is an indication of a rich fuel condition. These are possible causes:
Fuel Injectors: A leaking or dripping fuel injector will cause a rich fuel condition.
Fuel Pressure Regulator: A stuck closed fuel pressure regulator will cause a rich fuel condition.
Fuel Return: A restricted fuel return line will cause a rich fuel condition.
White/Gray Smoke: White exhaust smoke is an indication that coolant is burning in the combustion chamber. These are possible causes:
Cylinder Head: A crack in the cylinder head (around the coolant jacket) will cause coolant to enter the combustion chamber.
Engine Block: A crack in the deck of an engine block near the coolant jacket will cause coolant to enter the combustion chamber.
Head Gasket: A damaged or blown head gasket will cause coolant to enter the combustion chamber resulting in white/gray smoke coming from the tailpipe.

Blueish white smoke comeing from exhaust


Hello There

White smoke when first started is normal. If white smoke continues you have an internal coolant leak, i.e., cracked head/blown head gasket.
Black smoke is caused by a rich fuel condition.
Blue smoke is caused by oil consumption.

You need to check your oil cap for yellow/white gunk on the cap if you have this then this is a sign your head gasket is cracked. Check to see if your radiator coolant level is down this is also another sign.

Hope this helps. Please don't forget to rate me.

Many Thanks

Why is my 2007 Nissan sentra 2.0 using 1 qt of oil every 600 miles?


More than likely u have a leaking valve cover gasket unless your seeing smoke than it might have a burnt valve guide or guides if its smoking real bad than it could have bad rings and you don't want that cause then u half to tear the motor down basically rebuilding the motor

Its sputtering and blowing smoke out of the tailpipe. whats the problem?


Hello! #1 question; Is the Check Engine Light (CEL) on? This means the computer has stored a fault and in order to troubleshoot the cause I'll need the code...Take the vehicle to an auto parts store and, for free, they will read the code...Send it to me...

If the CEL is not on; Pull the Positive Crankcase Ventilation (PCV) valve...Give it a shake...If you do not hear the little ball that lives inside rattling around; you have found the fault...Replace PCV valve...
See photo below...The PCV valve is located in the rear valve cover, just behind the throttle body

MY SUZUKI GET TOO MUCH WHITE SMOKE,BUT I HAVE PUT ENGIN FLUSH, CHANGE THE OIL AND THE OIL FILTER,ADD ANTISMOKE TO FUEL BUT NO CHANGES PLEASE!!!


There has been an issue of Suzuki engines smoking due to the PCV. valve or the baffles under the valve cover. One method of curing this is to place an oil separator between the vacuum line from the intake and the PCV. This will make for the need to keep an eye on it as it will fill up with oil eventually thus negating the purpose of placing it there in the first place. I think the big fix would be to remove the valve cover and check the oil baffles and filter therein. The problem is that oil builds up at the location of the PCV and is getting sucked into the intake via the vacuum hose to the intake. The quick fix? unplug the PCV and plug up the vacuum hose to the intake. This will get you by until you can get it to a mechanic. Anyway, That what I know. hope it helps

My engine is smoking and smells like burnt oil? maybe. there is a gear symbol with an ! next to my park/drive on the dash board


Perhaps oil has leaked onto the exhaust manifold.
Check the oil pressure also.

Oil LeakOil leak, probably valve cover gaskets need replacing or just tightening. Also if it started suddenly after an oil change, the filter may be leaking, or you spilled oil on the manifold.
This MY & others had problems with both the cranshaft oil seal. The rear one leaks onto the exhaust and can make a horrible burning oil smell, notably when you stop after a long drive.
Head Gasket
Outbacks up to 2001 have issues with head gaskets, its a widespread problem. If the smoke is white and smells sweet it is coolant leaking into the pistons via a head gasket. Replace the head gasket before it fails. If you blow the head gasket it will ruin the engine.
Cam Seals
It is most likely the cam seals dripping small amounts of oil onto to the bottom of the engine block. When the engine warms up, it will burn the oil off.

Toyota 1998 Carib 1.6L using excessive engine oil?? Well maintained and looked after car can't understand y?


Well for starters, that oil has to be going somewhere, obviously.  So most likely it is the piston rings, these wear out over time regardless of how well taken care of your car is.  Check the exhaust out while the car is running, if there is a white-blueish smoke, thats piston rings.  if it is more grey-ish, thats most likely a head gasket, in which case check the coolant overflow for color, and remove the oil filler cap and look on the inside, if you see a nasty looking white film, thats caused by water/coolant in the oil, most likely leaking through a bad head gasket.  Or it may be leaking out somewhere, if there are no puddles it may be leaking near a hot exhaust pipe/manifold and burning off.  
As long as you keep enough oil in it, it should be fine for a few years, just get it fixed eventually.  in the mean time you can also use oil additives to help string things along, ask the rep at your local auto parts store.  hope this helps!
