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

Car runs hot when in traffic or in idle temp rises go down when car begins to move

It maybe just a bad thermostat.
First check coolant level. If it is low, pull out the engine oil dipstick and check the top for whiteish foam or cream . Also check the engine oil filler cap for the same. If the foam (or cream) is present you could have a bad head gasket or warped or cracked head.
If there is no foam then you most likely need a new thermostat.

I have a bmw 318 the the amber light of exhaust emission deteriorated has come on There is also cream colour muck inside the engine oil cap. Is it safe to drive. The oil was low.Thank you. Kanica.

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.

My car is slow in starting making white smoke when fires up smells a bit fuel is also low in power when driving under 2500 revs.any ideas to this problem not believe to be maf or air sensor

White smoke is usually a sign that there is a problem with the cooling system. Blue smoke is fuel related.
Have the cooling system checked at a guess I would say this is water leaking into the cylinders which indicates a cylinder head gasket fault. A faulty cylinder head gasket would also cause slight loss of compression which could explain the loss of power. remove the oil filler cap on the engine if there is a sign of a light brown (cream) coloured substance (water contaminated oil) on the cap or in the cover then the head gasket needs replacing also check the dipstick.
Hope this helps.

I've never actually put oil in my car before!! (the service people do it) Is the container which says OIL AFT ONLY where the oil goes?? Engine oil that is! (and I've mislaid my owners manual) BMW 318i s...

No! I believe this is the cap for your automatic transmision, do not put engine oil in here. The fill for the engine should be on top along the rockercover. If the you can find the dipstick for the transmission, the oil should be a slight red/pink colour. The dipstick for engine oil, the oil on the stickwill be dark brown to black colour!

pull out oil dipstick and see if it is over full. might have gas smell to it, if it does then the engine is flooding. also might be antifreeze getting into oil, this will cause gunk to build up. good luck

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.

Change transmision oil

You don't say if it's auto or stick shift. So-

Auto. Start the engine until warm. Drive vehicle onto ramps, SECURE IT! front up, turn engine off. With engine warm, at the back of the gearbox is a drain plug (we'll deal with that first) Remove the plug and drain all oil out of the gearbox. On the bottom of an auto box there is a plate, if it is easily accessable remove the plate, taking care not to split the seal, Wipe off as much of the reidue as possible, then using a releasing oil, somthing like WD40, spray the inside of the plate and it disolves the final bit of gunk. Replace the plate, the plug, Wipe some clean oil on ALL surfaces that are touching, seals etc, and tighten. Under the hood is a dipstick, by the bulkhead, for the gearbox. Remove the dipstick, and with a funnel through the dipstick pipe, top up the gearbox with the CORRECT OIL until it touches the bottom of the stick, Start the engine and slowly, let the car run off the ramps. With the engine running, wait until up to temp, check your level again, it will have dropped, don't panic, then top up the same way until the oil is between the two marks on the dipstick.


Stick shift. the same as above up until I mention the plate. There isn't one! Remove all the oil, refit the plug. On the top of the gearbox, just off centre, is the re-fil nut. With the car on the ramp, refill with oil. The oil should have come with a flexi tube on top of the bottle, if not, use a funnel on a tube that fits into the nut hole on top of the gearbox, making sure you can access it though the engine bay to fill. Get someone to lie under the car so they can see when the oil comes out of the fill hole, that means it's full. Refit the filler plug, and reverse off ramps. There is no dipstick to check on a stick shift, you don't need it.

It sounds like a long job, but it'll take an hour tops!

Let me know how you get on, any further problembs let my know. Dave

Pull your dipstick and check the oil level on a flat area if it is down a hair this could be your problem if so add a little. then start the engine the light should stay off.

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.
