Question about Cars & Trucks

1 Answer

It's a 2001 Dodge Dakota 4.7L that may have a head gasket issue

There has been a yellow residue on the bottom of the oil fill cap; it smells a little like gas. There was also a white-ish residue in the oil fill tube. It has been suggested by knowledgable people as a head gasket issue. Looking to see the opinions I get here. If it is, what does it take to fix. It it something that can be done at home? Do I need to take it to a garage to be fixed?

I would go with the leaking head gasket, any shop can confirm this is the problem very quickly with a gas analyzer..

Greetings Operaman,

Unfortunately, the symptoms you describe as known as "gelling" in which the antifreeze seeps into the crankcase, indicating that your head gasket is indeed need of replacement.

I strongly suggest you refrain from driving your car and take it to get fixed. Reason being is because continuing to drive it can likely result in warpage of the head (which sits about the block).

Hope this helps.

ok, there are two issue that may be occurring. First, there may be some abnormal ware in the cylinder walls and the rings may be bad and, the oil additives you may use can also separate the componets of the oil blend and produce this film as well. if you are experiancing a misfire or sputtering, it may be a valve issue.

time for a new car.  You single handedly ruined this motor.  Don't waste anymore money on this car,  buy another car and do the prescribed maintenance as required. Think of this as an expensive lesson.

Known issues or not,It sounds like the head gasket is blown,or it has a cracked head.If it was water it would be thick and light grey in color on the dip stick,But yellow indicates antifreeze leak that has not had time to mix with the oil.

I have a 99 chevy blazer it smoke when you give it gas it dont smell like oil no water is coming the tailpipe it is a strong smell of gas


Sounds like a bad head gasket. This will need to be replaced soon if its bad enough to be smoking. One way to find out if this is the problem, is to look at the oil filler cap, if there is corrosion, white residue, or water, you most likely have a bad head gasket. Also check the oil thru the dipstick, if it looks
Like theres water or antifreeze in the oil this is also a sign of bad gasket.

Blowing white smoke


If you have overheated your car recently, then you possibly have a blown head gasket. Take off your oil fill cap (with engine off) and inspect to see if there is a milky substance underneath the cap. If so, bad news- head gasket. You can also check the oil dipstick for the same substance to verify bad head gasket, but usually it has to be pretty bad (gasket) or driven for a while before exhibiting any signs. The oil fill cap is a pretty good indicator. With the car cool, you can open the radiator cap and look and smell for anything other than coolant (fuel smell or oil slick). If so, probable head gasket.

How could I really tell if my head gasket really blown step by step


check running temperature,check oil filler cap to see if there is a creamy residue on the bottom of the cap indicates oil/water mixing same check of radiator cap,finally check oil dipstick if this shows contaminated oil this is a positive indication of head gasket failure, the rad/oil cap check may only indicate condensation reaction. HOPE THIS HELPS

Milky residue in oil cap


Probably water leaking into engine from head gasket. A few engines are prone to condensation from large cam cover surface area. Any oil or smell of petrol in water system?

Engine will not idle, high idle ok. 1985 aries 2.2L


usually when a car wont iddle it may have a blown head gasket , remove oil filler cap on rocket or tappet cover check for creamy coloured oil , if so blown head gasket , also when morot is cool remove radiator cap and check fro brownish residue under cap if so blown head gasket .
remove each spark plug if one or more of them is white on tip of plug water is getting into cylinder ..

if none of these some carby's or throttle body's have iddle screww which can be adjusted to speed up iddle , or if throttle body it may have an iddle soleniod which may need to be replaced ,
i hope for you is is just and iddle issue , both the solenion and head gasket arnt cheap to fix.
the soliniod although easier to remove and replace its cost is usually .... expensive on most makes of cars , dont know why just because there greedy dealerships !

hope you need only to adjust carby or check timing is o.k

good luck hope this helps

2004 dakota over heated.. pulled over turned off let it cool off now it will not start. it trys to turn over but nothing. What could it be


could have a bad head gasket. have it checked out . If you take radiator cap off and fill it with water, and try to start it, and water pushes out of radiator, then you have a blown head gasket or worse.

Lots of back fireing. does not run fast, white smoke


White smoke is generally a sign of buring antifreeze which is a sign of a blown head gasket. Pull your oil dip stick and see if the oil is milky white. Open your radiator cap and start the truck. Do you have lots of bubbling going on or is there a oily residue in the antifreeze? If so these are other signs of a blown head gasket.

Water came out when the oil cap was taken off on my bmw 323i


water actually came out of the oil fill cap? is there a white milky residue on the bottom side of the cap? did this happen when it suddenly got cold? if you pull out the dipstick, do you see "bubbles" on it indicating water is present in the oil pan?

i remember my 540i use to do this and there was a BMW service bulletin indicating such and it was not an issue. it only happened when it was really cold out (winter months), but then would go away in the summer. maybe that's why BMWs now have oil/water separators?

is the coolant level dropping in the overflow tank or in the radiator? if not dropping, then it may be the issue i mentioned above.

if you want piece of mind, take it somewhere for an oil change and have them put it into a separate container. if it was a head gasket that went south, then the oil & water should separate in the container and it will be obvious that jo jo jo is correct with the head gasket.

also give BMW service a call and ask if this is normal (some water vapor on the bottom side of the oil fill cap) during the winter months. hopefully its not an issue or it will be pricey to get the head gasket changed. good luck.
