Just done an oil check in my car, brown sludge!! help..?

theres all brown sludge at the top of the cap, whats going on....


Its not due a service for 3 months yet. Should i be worried?


No stupid answers please.Just done an oil check in my car, brown sludge!! help..?
just burned oil, nothing to worry about. as long as its not like mayonaise. (white or yellowish) in colour.





at the next service you could ask them to do an engine flush, which gets rid of all the sludge.Just done an oil check in my car, brown sludge!! help..?
If it's just at the top of the cap, it's nothing to worry about. As long as the oil itself (on the dipstick) is clean it's fine.
You must have a brand new oil change then. You should change your oil every 3000 miles. Even if you don't drive it that often, you should change it every 3 months. I am not sure how you decide oil should be changed if you feel it is not due for an additional 3 months. If you change oil too much it costs $30 for an oil change. If you change it too little, it costs $8000 for a new engine.
G'day Jessie....I am assuming that the sludge is under the cap where you pour oil into the motor. Is this correct?


Also....when you checked the oil level...was it correct?


How old is the car?


4 or 6 cylinder?


how many kilometres on the clock?

could be just due for an oil change but check your water bottle cap as well cause it could mean your head gasket is on its way out. you local garage will be able to tell you straight away.
Sludge on the filler cap indicates water in oil, could be cylinder head gasket on way out,does water level need topping up regularly? that`s a guide.
the sludge is probably a mixture of oil and water it is fairly common
it's probably just oil congealing with dirt on the cap of the oil filler. Old oil goes black and can have a gritty/grainy texture if you rub it between your fingers where carbonisation and metal fiolings have worn away. that's when you need to be worried and change your oil. Test the oil in the sump to check that it is not black in colour or gritty - if it is fairly clear or browny then it will be fine
So does this mean that your oil was recently changed? Because it should be changed every 3months or 3000 miles.
if its just brown sludge on the top of the cap I don't know but if you pull out the stick and see a whitish brown oil that seems to have a lot of white in it, yeah you have a major problem which could be 1 of 3 things. a blown head gasket a cracked head or a cracked engine block, mine was a cracked block, but if the oil isn't a light brown or whitish brown when you pull out the stick, don't worry,





if its a Pontiac grand am, or grand pre, its probably not a good thing they are famouse for cracked blocks.
Do you mean there's this ';mayonnaise'; forming under your oil filler cap? Just check you're not losing water, the water in the radiator isn't contaminated with oil and there's no strange bobbles on your dipstick.





If they're okay, it could just be one of those things, some engines do this if they seldom get the chance to warm up fully - it's just condensation. Might be worth getting your crankcase ventilation valve checked, though.
How old is your car.? this info could help.
It sounds like it might be mixing with some water.





If the actual oil level (check the dipstick) is low then top it up with some new oil, otherwise you might be best off changing the oil now anyway.
on top of ur cap? that is not suppose to happen even if the oil did got cooked up and become sludge. They suppose to stay inside the engine.


I think that on the cap are the left overs when they pour in the oils...


Well, to get a peace of mind, go do another oil change right da way. And see whats the outcome going to be.


How old is ur car tho? try to extend the info.


It also happens if ur engine is too old and it starts to burn oil.
brown sludge at the top of the car? do you mean the top of the engine inside the oil filler cap.is the radiator water level low? is the engine oil level high? more information please.
You do have a serious problem in the works and if not correcting it you could lose your engine.





That brown sludge is caused by excessive moisture or water in the oil and is quite common on engines with an aluminum head and even moreso if the rocker cover is aluminum because they condensate so much with temperature change.





The worst situation is if cooling system coolant is getting into the oil. If this is so, you do have a major repair as a head gasket has probably cracked and should be replaced.





There are gizmo additives claiming to repair gaskets but in the long run they are not dependable.





It is best to have an older experienced repairman look at the situation and determine what is best for you with consideration of the car value.





As for changing oil, well...2500 - 3000 miles is ideal but should always change filter too.





Don't panic...if there are no water bubbles showing on the dipstick and no brown sludge on the dip stick then it is probably just condensation around the oil fill hole which just needs to be cleaned more often. Have an experienced repairman look at it.





Do hope this helps.
You have engine oil getting into the cooling system of you engine, it could be a crack in the head or a blown head gasket,

Sludge is caused by water in the oil. Water can come from the cooling system via blown head gasket or a cracked engine block, but can also come from lots of short runs in cold weather. The main products of combustion are CO2 and water and if the engine never fully warms up, this water can get into the crankcase and form the sludge. Check the oil on the dipstick - so long as it is not a creamy colour in any way (light or dark) you probably do not have an immediate or urgent problem. If it is creamy, change it immediately and look for a a serious water leak. Otherwise, consider driving habits as above and monitor the cooling water carefully, remembering that it will rise and fall according to the engine temperature so always check it in the same condition. If you are losing water, most likely candidate is the head gasket, which should not be too much of a disaster. If you have to change the gasket, have the head checked for flatness before rebuilding.
get your oil changed
In most case if you indeed have brown sludge on the oil cap or on the dipstick you will likely have antifreeze entering the engine assembly, possible a blown head gasket.





I would first check and see if the vehicle is running hot and if it is then you have some serious troubles.





If the vehicle is not running hot have oil drain and check its condition but I strongly recommend that you do not do a engine flushing.





When you flush an engine and this turns out to be just sludge all of this sludge will go down to the lower portion of the engine and this will make your situation worst.





The sludge will most likely clog up you oil pick up, screen and probably your oil pump. I have seen many vehicles damaged more after flushing the engine.
nothing to worry about(yet).but if i were you,i would give it a good flushing out and a good oil and filter change.
