I concur with Steve. If you haven't changed the oil at least twice a year; do it straight away. Start your car and see if White Smoke comes out of the exhaust. If it does, you've cooked the head gasket and water is getting inside the cylinders. It's big bucks to repair. If the exhaust appears normal, then you are out of the woods and probably have a bad O2 sensor, or deteriorated catalytic converter. Using a light weight ball peen hammer to tap gently on it and listen for rattling. I said light tapping on the underside, not hammering as one would use for nails. The ceramic plates coated with platinum will break over time and cause restrictions in exhaust air flow... we call this "increased backpressure." This causes your engine difficultly in operating. (Like trying to inhale when you can't exhale.) Let us know what you find!

That's not good, cream coloured oily muck on the oil filler cap usually means water is in the oil. This would indicate either a blown head gasket or cracked head. Somewhere water is getting into the engine. I would get it looked at ASAP as major engine damage can occur if you havent already done so.

SOURCE: I have a BMW Z4 2003 2.5 with the exhaust emission

The Exhaust Emission Light can come on if the car is driven slowly over short distances.It will not happen on cars driven at speed. A short trip of ten miles at over 3000 revs should reset the warning light,although it may not go out for a couple of days after you have tried it . Hope this helps and saves a bill at the local dealer. JK

SOURCE: On my mini cooper I have a warning light

it isnt anything to be to worried about. it just means your not maintaining your car as much as you should be so its polluting more then it should be. Keep in mind that when you get the letter from your state to check your cars emission to see if it passes your states minimum requirements it will most likely fail and you will need to do everything to make it pass.
Examples: go to your focal shop most likely a jiffy lube does it the cheapest and best, ask for the fuel-injector cleaning. Its pricey but it will definitely help
Use better gas for a few weeks to clean out the engine. Such as BP or Shell
Change the Oil with more frequency so your car doesn't have to reuse old oil to run every 3,000-5,000 miles
change the transmission oil as well. This is also pricey but it doesnt have to be done as often as you think. Every 50,000-60,000 miles

You need to bring this to a pro, and make sure it's someone very familiar with Minis. possibly a bad converter, but could be a sensor or injection problem that is sending too much fuel down the line, making your post cat o2 sensor see trouble. Get after it quickly, and maybe you can save your quite expensive catalytis converter.

I have BMW 318 / 05 plate. The engine oil cap has cream colour gunk on it. The oil dipstick has just a tiny bit of cream gunk ... Why is this happening. Please help.

This is water foam caused by infrequent oil changes, poor quality oil (Quaker State, Pennsoil), or possible head gasket leak.

92 bmw 318 is runs good for 15 mins then it will start missin and engine lights on.i smell like oil smoke and i turn car off. what could it be ,could it be valve stem seals or what.

You smell burning oil. See if there is oil in your spark plug wells or down the exhaust side of the engine. If there is, replace the valve cover gasket. That may be related to the miss if there is a lot of oil on the plugs.
You say the (Check) Engine light is on. Your engine light will flash a code to indicate the problem if you turn the key to the On (just before it starts) and press the gas pedal all the way to the floor five times within five seconds.

Exhaust emission values have deteriorated

A few clarifactions pls...
Which Car....
Does it have a carburetor or a Multi Point Fuel Injection System
Diesel or pertol or Gas.

The most basic reason for poor emission is incorrect mixture of air and fuel.
if carburetor then you will have to get the correct mixture set . Its NOT a long procedure just adjusting 2 main screws.... But lat a mechanic do it.

If Multi point fuel Injection... then the injector needs to be cleaned This is a lengthy affair. Before opening this you could use fuel additive ment for cleaning the injectors..
Alos check if the manifold/ exaust pipe is not leaking from anywhere as this reduces the pressure and the burn is not total resulting in Emission..

There are fuel addetives that help clean the engine from inside.... but for that I would need more info so as to guide which addivive could be suited.

BMW 318iSE (1999) engine warning light

That sounds like you bought big problems. Oil ights indicate low oil pressure= BIG BUCKS. I would have a qualified repair shop check it out, A shop that specializes in BMW. If you are lucky, maybe the oil sender is just bad. They can also check out the Ck eng light. But the oil light is priority one.

You have a bad head gasket. You are leaking coolant into the engine block through the cylinders. This is why you have white smoke, and the extra coolant that doesnt get burned off is going into your oil.

Bmw 1996 316i i have had the head gasket skimmed new gaskets on there is white smoke coming out of the exhust. and the oil in the head is like a carmel colour like cream but its not losing power or...

Something is wrong with the head to engine connection. The white smoke is water burning from the sylinder(s) and the cream colored oil means you're getting water in the oil... this isn't good. You'll have to remove the head and re-assess this connection. Make sure the gasket is correct to all the water jacket ports and upon reinstallation, follow the correct torque sequence for the head.
I hope this helps, though it's not good news... sorry.

Losing oil on E46 316i 2003

hate to be the bearer of bad news, but i think your head gasket has failed causing the oil & water to mix in the engine. usually, the water enters the oil causing the milky cream liquid (check the under side of the oil fill cap for this same creamy liquid) and you wind up adding coolant since it gets low.

if the coolant is not getting low, then it may not be anything to worry about. in the colder months, BMWs have been known to display this creamy liquid on the oil cap. it disappears when the weather gets warmer. BMW has a service bulletin on this.

have a compression check done on it to see if this is truely the case. i hope i am wrong. and 1 pint every 2-4 thousand miles is not too bad.

The engine exhaust emission light on

it sounds like the oxygen sensor, air mass meter. check the crankcase breather pipe behind the engine ( cracks, common problem), it would be wise to have a computer diagnostic done, it will save u time and money
