Could you be a bit more descriptive by what you mean when you say "oil is coming at a piston once I start the engine" exactly what is happening?.

    if you put new valve seals in,if they were the rubber "O"ring if you didn't oil them they tend to roll during installation, if the seals were umbrella type they are moving up n down with the valve meaning they're pumping oil into the port they represent. intake or exhaust. to rule out a worn piston,broke ring,or ring gap aligned, or cylinder wear try a compression check.refer to manual and if the compression is correct the seals were improperly installed or defective.

SOURCE: oil keep getting on spark plugs and car will not

you might of not put the gasket on right, did you put the silicone on the corners? or didnt tighten the bolts enough. but if you are sure you did it correctly it is your valve cover it is most likely bent.

SOURCE: My 95 Accord 4 cyl burns a lot of oil. Compression

It means that your piston rings are worn out or the compression chamber or sleeve is worn out..4 stroke engine has compression rings and another rings for oil only..So even though you have compression it does not mean that your oil ring is not worn out..

SOURCE: Losing oil, no visible leaks. 120,000 miles

Hm. In my experience if you lose oil at the rate of 1 qt. per 800 mi. it's going somewhere. Actually, if you lose 1 qt. per 1000 mi. and change your oil every 3,000 mi. it's under $10 in oil you have to buy to keep it topped off, and some places say that's there's nothing wrong.

But, your case is a little more serious.

I think that it's probably leaking past the rings and/or valves and the catalytic converter is eating up the oil, so you see no blue smoke, like you would in a car that has no converter (I'm assuming you have a catalytic converter on your car as my 1981 Honda had).

After 100,000 mi. little irregularities in the piston cylinders can develop, and seals can gradually degrade. So, this is normal for that kind of mileage, although there are people who get over 400,000 mi. on their cars with just regular maintenance and driving highway mi.

You might want to try one of those slower burn oils designed for cars with 75,000 mi. and above. That might slow the burn off of oil down to acceptable levels.

Good luck with it.

SOURCE: pistons filling up with oil

These definately means that the rings are bad or the valve lines. if the smoke is white then those are the two suspects and you need a technician to look at it.

Hi does anyone know why my 2.4 tdci mk7 transit is hard to start 1st time in the morning once it's started its ok but when I try to start it in the mornings it a pig and when it does start I get blue...

This might help explain the causes and where the fault might lie! You didn't mention the mileage, if high it could be worn valve guides or seals!

Blue smoke is an indication of oil being burnt. The oil can enter the combustion chamber for several reasons.
  • Worn valve guides or seals
  • Wear in power assemblies (ie cylinders, piston rings, ring grooves)
  • Cylinder glaze
  • Piston ring sticking
  • Incorrect grade of oil (eg oil too thin, and migrating past the rings)
  • Fuel dilution in the oil (oil thinned out with diesel)
At cold start, blue smoke is often evident, and can reflect reduced oil control, due to fouling deposits around piston rings or cylinder glaze (which is actually carbon deposited in the machined cylinder crosshatching. These tiny grooves actually hold a film of oil, which in turn completes the seal between the combustion chamber and the oil wetted crankcase). Blue smoke should not be evident at any time, but it is worth noting, that engines with good sound compression can actually burn quite a lot of oil without evidence of blue smoke. Good compression allows oil to burn cleanly, as part of the fuel. It is not good though!

What could be the problem after i put in new valves seals and new piston rings there is oil coming at a piston?

Sounds like you have a motor for a Cessna 150 / airplane which looks like a vw engine except it has two plugs with two different magnetos to run them. Come in 4/6 cylinders usually with one central carburetor. Double check position for gaps in piston rings and that there in the right places. If not offset correctly the compression will be low and pass/dump oil into cylinder. Also check the cylinder sleeves for cracks. I would recommend that you try using die penetrant inspection kit if you cant find the source. The sleeve is installed in cylinder heads. And cylinders can be removed from main body for inspection/replacement on a Cessna engine. And if I'm right about the motor you got then you can probably look up info on motor. Any airplane part has 100% traceability and you can get down to who made it, what part of world the rock was minned to make the engine and even a sample of material will be on file along with quality testing and any other information they have on it which should be all of it. Good luck with it.

Burning oil and you can drive for awhile and then it will die on 2001 grand am 2.4l

My last three cars have come equipped with that particular engine. Although it is very rugged, if the rings or valves are worn then you just might be burning oil. Pistons are usually equipped with rings at the top. The rings not only seal the combustion chamber, but they also scavenge any oil that happens to drip down the sides of the cylinder before the compression stroke occurs (this can happen if your valves aren't seated and sealing correctly). The oil provides lubrication for the piston so it can slide up and down the cylinder. The rings take care of the oil that is there, as noted.

If the rings are gone then two things happen. The engine doesn't seal and it leaks air. Though the cylinder may fire, the amount of fuel isn't right and the power will be way down. Attempting to drive it is like driving with an anchor attached to your car. You'll get ahead, but very slowly. The engine may also sound horrendous.

The same condition can occur if the valves aren't seated or sealing correctly. Since the engine is not sealing and is leaking, then the amount of pressure available for proper compression and proper engine operation is not available. The result is poor performance.

Like leaking rings, a worn valve or valves will not only cost you mileage, but your car's engine may sound like a cement mixer. Worn valves also can cause a flood of engine oil to cascade down the cylinder walls, overwhelming the rings, causing burning oil.

I would suggest having a compression test run to indicate which piston is bad and then having that piston serviced. To bring performance back, it is a good preventative measure to replace the rings and valves, just in case. Worn rings could indicate that the valves are about to go and vice versa.

Burning oil can also be caused if a piece of your car's head gasket is blown out. Your engine will run but, in this case, your engine will sound like a tea kettle. It will also run that way, too.

To diagnose this problem, you start with a compression test of each cylinder. If the cylinders are within specification, then the culprit is most likely a blown head gasket. To repair it, you will have to have your car's valve covers removed, exposing the gasket. Then after cleaning the area and applying either the gasketing material or a gasket itself -- with correctly dressing -- and putting the covers back. The covers should then be torqued down to specification.

Excessive fuel consumption on vw caravelle 2.5i

Clogged PCV Valve
The main purpose of the PCV (positive crankcase ventilation) valve is to recirculate blow-by gases back from the crankcase area through the engine to consume unburned hydrocarbons. Blow by is a mixture of air, gasoline and combustion gases forced past the rings on the combustion stroke. The PCV system usually has a tube leading from the crankcase to the carburetor or intake manifold. Vacuum within the engine intake manifold pulls blow by gases out of the crankcase into the combustion chamber along with the regular intake of air and fuel.
Worn Piston Ring Grooves
For piston rings to form a good seal, the sides of the ring grooves must be true and flat - not flared or shouldered - and the rings must have the correct side clearance in the grooves. Normally, automotive ring groove side clearance should not exceed .002-.004. As the pistons move up and down, the rings must seat on the sides of the grooves in very much the same way that valves must seat to prevent leakage. New rings in tapered or irregular grooves will not seal properly and, consequently, oil will pass around behind the rings into the combustion chamber. Worn grooves are usually flared or tapered causing increased side clearances which permit more than the normal amount of oil to pass the rings into the combustion chamber. Excessive side clearances also create a pounding effect by the rings on the sides of the piston grooves. This promotes piston groove wear and, if the condition is not corrected, breakage of rings lands may occur.
Cracked or Broken Ring Lands
Cracked or broken ring lands prevent the rings from seating completely on their sides and cause oil pumping by a process similar to that described in #7. In addition to this, they also lead to serious damage to the cylinders as well as complete destruction of the pistons and rings. Cracked or broken ring lands cannot be corrected by any means other than piston replacement and this should be done as soon as there is the slightest indication of a crack.
Worn Valve Stems and Guides
When wear has taken place on valve stems and valve guides, the vacuum in the intake manifold will draw oil and oil vapor between the intake valve stems and guides, into the intake manifold and then into the cylinder where it will be burned. If this condition is not corrected when new piston rings are installed, an engine is likely to use more oil than it did before because the new piston rings will increase the vacuum in the intake manifold. When gum or deposits on the valve stems are removed - a procedure recommended when overhauling an engine - the seal previously formed will be removed and leakage will be more pronounced. This is particularly true on overhead valve engines where loss of oil may occur on the exhaust valves as well as on the intake valves. High oil consumption caused by too much valve guide clearance can frequently be cured by reaming or nerraling the valve stem. In some cases new valves may also be required. Use of a permanently bonded valve stem seal will give added insurance against oil leakage on complete engine overhauls or on valve jobs.

I have blue smoke coming out of the exhaust of my 1998 dodge caravan

Blue smoke is usually an indication of bad rings, which allows engine oil to be burned as you drive. The fix requires engine teardown, pulling off the heads, removing the oil pan, and removing the crankshaft, rods, and pistons. The cylinders may need to be bored, but at the least they will need cleaned up with a hone. The old rings taken off and new rings istalled. If the engine needed bored, then new pistons must be installed. Then, put it all back together.

Hope this helps you

What make my 1993 blazer smoke

there are a few reasons for the engine to smoke. first determine the color of the smoke, white smoke means its burning water...possible bad head gasket or cracked block or cylinder heads. If the smoke is black...means the fuel mixture is to rich, getting to much fuel. If the color is is burning oil, meaning the oil rings are worn, and or the valve seals are worn as well. if it smokes when you first start it, and then stops after a few minutes, once the engine is warmed up...probably bad valve seals. if it continues to smoke it is more likely the oil rings. Valve seals being cheaper and easier to repair, where as the oil rings means the motor needs to be rebuilt or replaced.

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)

I am getting oil in the spark plugs

Oil on the spark plugs is an indication that the rings on your pistons are failing and allowing oil to pass through into the combustion chamber.
Usually this is indicative of a motor with a lot of miles.

The solution is to replace the worn rings, but be prepared for other components which will need to be replaced once you start the process.

OIl leak in 2001 Grand Cherokee Laredo

valve cover gasket is like $20 and a do it yourself job, just buy a manual like a chiltons from an auto parts store. if it was valve cover, the smoke would be coming from engine, not tailpipe.

rear seal is in between engine and tranny, this would cause oil to leak on ground, but not to burn

if smoke is coming from tailpipe, your piston rings might be going bad. that is an expensive repair, but switching to synthetic oil may give you several more years of life out of the piston rings, synthetic oil has a way of soaking into bad piston rings and temporarily making them like new again, unless they are already too far gone.
