Possibly blown head gasket 2.5s altima 2003?

Question

Ive posted up numerous questions about my engine possibly having a blown head gasket what are all of the "FULL SYMPTOMS" to determine that my head gasket it blown, the car wont start and it just makes a noise as if the battery is low but I just got it charged and an hour later the vehicle still reacted the same if you'll can look at my previous answers and questions, please do so to get a better understanding of what thel im am talking about thanks and god bless.

well I got the car running I did notice while I was looking at my sparkplugs that one of them had oil or water on it 4th cylinder, after I replaced that one the car finally started, once I started it up and running it was able to drive and all but the idle was really bad, the vehicle shut off numerous times while driving it , I drove the vehicle down the street 10 mph and I could still hear the gasket making that loud awful noise, I checked the oil and no milky substance was in it, but I am running low on coolant and water in which im guessing the head gasket is definately blown. (once the car started after sitting for two months there was white smoke coming out from the engine area and I smell the substance of gas very easily.Everything else is ok its just my head gasket and spark plugs that need replacing, also a oil flush and coolant flush is also needed. If you'll have any suggestions or ideas whats best for the vehicle please let me know, I mean I know I have to replace the gasket

Answer 1

Unless its been severely overheated i wouldnt worry bout a headgasket. Id check your battery terminals and positive connection on the starter. Did you run it low on oil??? A quick check for headgasket iif it bothers you is to buy a block tester, which is a tube of liquid you put over your radiator fill hole to detect any exhaust gas in your cooling system. A no-start is probably more of a power issue, check connections.

The worrisome condition is the reported lack of compression. It isn't clear from the pictures in the source whether it is true for your engine, but normally cylinders 7 and 8 are in opposite banks. If so that argues against a failed head gasket, in which a common failure is a blowout between two adjacent cylinders. If the compression is actually bad, ignition fixes won't help. If you do have two adjacent cylinders with low compression a cylinder head gasket failure of that type is confirmed by doing a leak-down test and seeing if there is air coming from the adjacent cylinder when the first one is pressurized. If the lack of compression is confirmed and the indications don't point to a head gasket, the next step is to remove the valve cover and do a visual inspection of the valve operation as the engine is cranked. Some engines are prone to sticky valves and it is possible there is something out of whack otherwise. If the head gaskets are bad, replacement would be around $1100 to $1400. You can put your own location in the second source for a more accurate range. Almost any valve repair (beyond adjustment or lifter replacement) will cost slightly more - same labor and parts but added machine shop charges. Figure a couple hundred more.

here's an easy test. first check the oil. if it looks like chocolate milk and it's overly fuul, you have a blown head gasket. second, remove the radiator cap (while the engine is cold for safety) and try to start the car. if the antifreeze comes shooting out the top of the radiator, the head gasket is definitely blown. If the car overheats and the radiator is mysteriously empthy or low with no obvious leaks, then the head gasket should be suspect. Replace it, change your oil and oil filter.

Answer 4

a blown head gasket will make your oil a milky color and it probably would start unless it was locked up, i would look at my oil, and then check my water level to see if it was low , if your oil is a milky color and you low on coolant than it probably your head gasket .. but from you comment it sounds like it is just an electrical problem..
