Valve guide wear causes this. It's not a big issue, but if you ever have the heads off, have the guides replaced or knurled.

    I agree. I would not do anything about this unless/until you have to do other repairs. It will gradually get worse, but until the oil consumption becomes significant, just ignore it.

1988 suzuki samurai . checked compression # 1 180 # 2 140 #3 180 #4 180. #4 plug was gummed up. Engine sounds good.could it be valve stem seals or head gasket.Has 2 barrel carb.and header smokes bad


the compression is not bad however #2 is a bit low. what did the plug look like on #4. was it oily in appearance or chalky white. if it has an oily appearance then that cylinder is burning oil. it could be valve seals or valve guide clearance is too much or oil rings for that cylinder. the other colour is carbon meaning the cylinder is not burning properly. could be a weak ignition component that affects that cylinder or the cylinder has a lot of carbon build up in it. if it was white in colour then your burning coolant. not sure what you mean by header smokes bad, do you mean at the head if so then you may have something leaking onto it and its burning off.

Smokes on start up


Smokes blue on cold startup = leaking valve seals, which really don't affect drivability if it stops 1-2 seconds after startup. To fix you need new valve seals/heads rebuilt.

If it smokes while under load, then the rings are worn, letting oil seep past the rings into the compustion chamber.

Have you let this car run low on oil? Leaking valve seals usually present themselves if the car has been sitting a while, drying out the seals/cracking them. Worn rings should only present themselves after very very high milage, such as 300,000 miles or more. Somebody has not changed the oil on a regular basis, or just never changed the oil, or only changed the oil like every 20,000 miles.

To bring your engine back to normal, you will have to overhaul the engine and have the heads rebuilt as well.

My harley smokes


all engines do cold. its water vapor and or the hot exhaust, causing the air, to change dew point, (looks like steam)
on the white smoke smells like burned oil , it is, and is slow to dissipate like steam, (see moms tea pot , and steam fast dissipation?)

if it is oil , its most likely bad valve guides and seals, or both.
if a compression leak down test passes, its not rings, (mostly)

1995 Oldsmobile 88 LSS 3.8 smokes at idle


Valve stem seals. Oil is thicker when cold (hence no smoke when cold) Vlave stem symptoms are when engine at idle (high vacume) oil is pulled through the guide seals, when you take off from lights get bit of smoke until oil is burnt. Ring symtoms is it would be blowing smoke all the time especially at higher rpm for extended time ie: driveing. Have you thought of trying a thicker oil? what oil grade do you currently run?

Burning oil


Most of the time, when you first start your engine and it smokes, then the smoking slows down after the engine gets hot; this is a sign of valve seals, because the seals get softer when they are hot and re-seal themselves. If your car smokes all the time, hot or cold this is sign of bad oil rings, because of the oil being forced up past the oil rings, into the cylinder.

When i stop for awhil and then i take off it smokes like a blue color it only happens when the engine is hot not cold people have told be it's the valve stem seals and others have told me its the piston...


If it smokes blue only when you first start it, it is the valve stem seals, that is caused by oil seeping past your seals into the valves and when you first start it the seeped oil gets burned on ignition. If you have blue smoke all the time when you are driving, than it is the piston rings, either way you should look at replacing your motor soon with either a good used Japanese engine from Japan or a rebuilt or remanufactured engine.

Blue smokes come out tailpipe when i start the car but stops afte


Helllo there
Symptom: Gray or blue smoke from the exhaust. You notice gray smoke coming from the exhaust when you start your car. The smoke may or may not disappear after the car is warmed. If it is, it is less noticeable. The smoke may have a bluish tint to it. Possible causes:

  1. The engine's piston rings may be worn.
    The Fix: Replace piston rings. (Generally not a DIY job)
  2. The engine's valve seals may be worn.
    The Fix: Replace valve seals. (Generally not a DIY job)
  3. Damaged or worn valve guides.
    The Fix: Replace valve guides. (Not a DIY job)
Symptom: Engine uses more oil than normal, and there is some smoke from the exhaust. The oil level is low between oil changes. It appears that the oil is being burned by the engine because of the smoke in the exhaust. You may or may not notice the engine doesn't have the same power as it used to.
Possible causes:

  1. The PCV system is not working properly.
    The Fix: Replace PCV valve.
  2. The engine may have mechanical problems.
    The Fix: Check compression to determine engine condition.
  3. The engine's piston rings may be worn.
    The Fix: Replace piston rings. (Generally not a DIY job)
  4. The engine's valve seals may be worn.
    The Fix: Replace valve seals. (Generally not a DIY job)

Smokes at idle, not while driving.


you have hit the nail on the head ,starting a cold engine and just leaving it to idle takes a while to warm up ,but driving it straight away which is what you should do get the engine warm quicker ,also reduces your carbon footprint.When the engine is cold it burns oil till the correct clearance and tolerances are reached .

Exhaust smokes when engine starts


Most common reason for that is worn valve stem seals and or guides or gunk buildup in the cylinder head blocking oil return holes.... Or, broken piston ring or burned piston lands. (use compression test to verify that) Knocking can be from oil detonating in cylinder or bad rod bearing etc.

I have an 02 axiom and it burns oil like crazy.I have to put a qt


Most if not all Isuzu's consume oil due to them having a smaller ring size. The result is Blow-By, where the oil is burned internally and gets past the rings. It shows no visible sign of smoking, but does leave a lot of carbon build up within your engine, I recommend using Seafoam, found at most auto part stores. Use half a can with a warm engine, through your vacuum line on your brake booster. and the rest can be used in your fuel!
