Hi..there..
Ok..going by your desription id say unfortunatly you have either headgasket failure "more than likely" or the heads cracked..either way thats usually the reason for the cream/sludge substance on the dipstick or in the sump or even under the oil filler cap and inside too..because the coolant is mixing with the engine oil caused by the failed headgasket or head and thus you get that sludge all around the engine...so from now on the best thing you can do is to get it to a garage to confirm - then gather quotes to get the headgasket done..depending which engine you have you will need to the timing belt/water pump replaced along with the gaskets..the head should also be checked for cracks/warping..they will also need check the coolant pipe work for cross contamination too and clear out as they find...but as above thats about the sounds of your problem goinf by your desription of events..I do hope this helps....if you require to ask anything further then please do before you rate
