When i filled the oil up on my car i had a black gooey mess under the filler cap.?
Answers:
Look at the dipstick. If the oil on it is clean then muck on the filler cap is due to condensation of moisture due to only going for short runs. The water never gets hot enough to evaporate.
Look inside the valve cover, this is usually clean. Wipe the cap clean and check the hose from the valve cover to the air intake/cleaner to see it is clear.
This happens more on old engines with more blow by past the pistons.
If it's got in this state due to wear whatever you do it will come back and cleaning it out is a waste of money.

old car? its the norm. more so in ford for some reason
Not knackered, need to get engine flush.Put it in run it and empty it and put new oil in
Sounds like you need to change your oil, not just fill it up. Get yourself a Haynes manual :)
first off how old is your car and what make is it?if there is goo inside it could be water in the engine.you will have to flush the engine out and refill with new oil.this can be done easily by yourself but you just as well pay a garage to do it.
change the oil put new stuff in.Run engine for about 200 miles then change the oil again and it will clean the inside of the engine.
Oil change and there is something they sell for oil that can prevent that from happning again.
pretty normal, replace cap or clean. make sure you oils not mixing with you water, should be fine otherwise, it happens because the engine crankcase circulates fumes and oil mist which build up over time.
Was it more greyish than black? You may be leaking water from the pump. Gaskets will need to be replaced. Have fun with that!
buy some engine flush at the auto parts,and do what the derections say,easy fix
its an escort isnt it? its got the black death.. your engine needs to be flushed. basically its old carburised oil, which gets pumped up from teh oil pump scavenger, and settles out in the rocker box.
remove the cover, its got a rubber gasket so it wont need replacing. (or it shouldnt) and dunk the whole tin cover into a big plastic tub, and fill it with hot soapy water.. and scrub it out..
(we get them steamcleaned ) then after replacing it, drain out half the old oil, and add a pint ot two of parrafin or diesel (DONT USE ANY OTHER FUEL.) run your motor for 20 minutes, drive a mile or two around the block, draiin it and refil with fresh oil.
older fords do this. but ive seen them like boot polish, and they still ran ok..
good luck. and to get it off youll need a 10mm 12mm and a phillips screwdriver.
As oil heats up some will evaporate, and then settle at the top point of the engine, which is the cap. Thats all this is, nothing to worry about. If its a creamy colour though check the rest of the oil is black still. If so this will clear, its just a little water vapour reacting with the oil, however if all your oil turns creamy, thats the only time to worry.
I dont like the sound of filled the oil up.
Sounds like an oil burner, worn cylinder bores and piston rings allowing oil up past the rings where it produces carbon deposits and the blow by allowing the resulting carbon to contaminate the engine oil. I you have topped up the oil try 20 miles or so at 70 on a motorway/dual carriageway, get the engine hot, then stop at a convenient place and see if the gooey mess has disappeared, often oil gets emulsified if the engine does not reach normal operating temperature, and will magically disappear, as will a couple of pints of water leading to a dramatic drop in oil level !
Best thing is to change the Oil and the Filter using a good quality non synthetic oil like GTX,
It is a good idea to clean it up if you are a DIYer, use a flushing oil etc but drain the oil with the engine hot, not good health and safety advice but ithe hotter the more contaminents you will drain with the oil howeve the black will come back, basic problem is failing to change the oil often enough.
Fords often suffer from worn camshafts, leading to a drop in performance nor helped by not changing the oil often enough
so I guess you probably need a recon engine and in future change the oil every 6 months.
