Hello Aaron, Bad valve seals can cause your engine to smoke after start up and clear up after a few seconds of running. Sometimes the valve seals become hard and brittle. They can break up and restrict the oil return holes in the cylinder heads, causing oil to seep into the cylinders through the valve guides.
A leak somewhere, as it is unlikely it suddenly burnt so much in 6 journeys unless you went to Punta Arenas and back.
Obvious as it sounds I'd look first at the filler cap, sump plug and filter to see they are tight (but don't overtighten), then elsewhere. Give the engine a good clean with degreaser and a hose, then drive a short distance have have a look all over the engine for oil seeps. It is hard with new oil to spot these, so it may take you a few tries.
A set of wheel ramps helps a lot, as the leak may be on the lower parts.
any smoke from the tail pipe.if it is ,it might headgasket leaking from inside the engine or the valve stem.check the PCV system ,it might block it & oil is going to intake system.check the PCV system & the vent hose first.
Hi,this should be normal,with most older cars you see this when tempricher drops,let the car run for about 30minits keeping an eye on the water level and tepricher,should cleer,if tempricher gose up or lose of water then it could be water leaking into the pistion bores or head cracked,hopfuly it will cleer,good luck.
The valve guides in the cylinder head are probably worn, allowing oil to seep into the cylinders overnight and burn off when you start up in the morning. That is why you're loosing oil, it's being burned off.
oil in spark plugs indicates that the cylinder head gasket is leaking and allowing oil to seep into the cylinders. if engine is running you will also have blue black smoke from the exhaust.
alteratively the piston rings are so worn that too much oil is passing them and spraying up on the spark plugs but that is not normal on all cylenders at the same time maybe only the one. also there would be a very low compression when checked with a compression guage.
second check is to remove the oil filler cap and see if it has a white emulsion on it this also indicates that the coolent water antifreeze is mixing with the oil at the cylinder and causing this.
the fix is to have the cylinder head removed and the gasket replaced, to ensure the head is not warped and skimming on a lathe is also a good idea.
if this is the original engine then at 16 years old it maybe time to replace for a recoditioned engine or a new one if the rest of the car is in good order.
If the smoke is white it would indicate water/coolant getting into the combustion chambers from the cooling system. (Usually caused by allowing engine to become excessively overheated when cooling system has run dry). If this leak is bad enough you may also see a water and oil emulsion on the oil dipstick due to water runing into sump.
If the smoke is blue/grey it would indicate eccessive oil being burnt in the cylinders due to worn, broken or stuck piston rings. This problem shows up as having to constantly top up oil level every day or two. If the smoke only happens when engine is first started then it means worn valve guides or valve stem seals.
The first problem (white smoke) will requre the removal of the engine head to replace gasket and have head face machined,
The second problrm (blue/grey smoke) will require further diagnosis by a mechanic to locate the true cause and may mean a total engine overhaul.
If the smoke is blue, it's burning oil
The cause could be the valve guides are worn letting oil seep into the cylinder, head gasket, or worn piston rings.
If the smoke is white, it's a blown head gasket.
