The cylinder pressure may be fine but the leak might occur from the coolant part of the gasket, possibly incorrectly tensioned bolts. Try replacing the gasket (at the very least do a visual examination) run the car for 20 mins with the hood up and watch the area closely around the plug area and note if any hoses are leaking nearby.

SOURCE: Car getting too much fuel at spark plugs

Hello Velma!

It sounds like ther might be an intermittent ignition (spark) problem... when the plugs don't fire, they will get wet with fuel...
So check all of the ignition components, make sure there are no loose connections to the coils are plug wires.

It is also possible that there might be a problem in the fuel injection, such as an injector stuck open and continuously feeding fuel to its cylinder (which would show as only ONE plug being wet), or possibly a bad fuel pressure regulator, letting fuel pressure in the injector rail go too high and causing an over-rich mixture and engine flooding (symptomatic of ALL plugs being wet).

Once the engine is "flooded" it is sometimes hard to "clear" the engine with modern injection systems, but try this: Hold the accelerator to steadily to the floor while cranking --- DO NOT PUMP THE PEDAL! --- This will allow the maximum amount of air to mix with the overage of fuel in the cylinders and help the engine to eliminate the excess without also adding too much back in...

If you still can't get it to fire off doing the above, then remove the fuel pump relay or fuse and repeat the above until the engine tries to run.... It will run briefly until it fuel starves and dies. Then replace whichever you removed and try starting again with fuel delivery back in service.

Velma, I would have answered this sooner, but I've been on a "road trip" and only recently got back home. If you still have problems, please post a comment describing as best you can the situation --- you have to be my eye, ears, nose, and hands in this long distance effort! Also let me know why the head gasket blew, if known... Racing or overheating? If this does help, please remember to rate my assistance --- your approval is my ONLY compensation for providing this help!

Thanks!

SOURCE: Coolant overflowing out of expansion tank no boil no steam

As you've stated driving around town it's fine, and everything is working well. For the symptoms, there are 2 possible causes:
1. Your cooling fans are not working.
2. Your radiator needs to be replaced.
I'm sure you can determine which it is, and I wish you luck on your repair.

take out all the spark plugs and put a radiator pressre tester on the radiator and pressurize the system, then inspect each spark plug hole for coolant. you will find out what cylinder or head will need service. How did this car run before sitting? Blue smoke is not good, although it doesnt sound like you have run it long enough to verify any real cyl problems. if its smoking it may be overhaul time. and the complete engin ewill need disassembly.

SOURCE: No boil or steam when coolant overflows after shutting off engine

The only real way of checking for warpage on any head is by using a bar that extends from corner to corner on the head. The bar must be certified as straight (you can actually buy one from a tool dealer) since you likely will have little use for it, you can also have a good machine shop check that. Additionally, you should have had the heads magnafluxed (crack checked). The deck on the block should also be carefully examined and cleaned.
You are on the right track if you are going to do another hydrocarbon test. That will verify if you are getting a proper seal at the head gaskets or have any other seal problems (like cracks).
It seems as if you have done a very careful job and I know you don't want to take it apart again. The things you mentioned though do appear to point to exhaust driving coolant from the engine.
You can check the actual antifreeze mix with a simple ball type hydrometer. Anything except 50/50 will change the boil point of the mixture in a direction that isn't good. One thing I'd check is that you may still have an air pocket in the system somewhere. Make sure when filling that the heater is on high heat. One trick for getting the T stat to open without an air bind is to turn the engine off as soon as the temp approaches the opening point (195 (f)) then re-starting it in about three to five minutes, the engine temp will continue to rise during the time it is off but there will be no flow, allowing air to escape without fighting the coolant flow. Once re-started, add coolant slowly so the stat does not close again but add just fast enough so it does not overheat. One other item...If you need to take it apart again, don't use any kind of steel shim gaskets for the heads. Though a composite gasket will many times lower compression a bit, they also seal better. I use fel pro blue gaskets in everything. Unless I was careless or something got by me (not often) I never had a problem with any engine I ever built or repaired. The only application where I did not use them was in fuel engines where they were "o" ringed with stainless wire and used solid copper gaskets. (way different than a street engine!!!)
Have that hydrocarbon test done ASAP. No sense messing with it 'till you have that squared away!
Good Luck!!!

have the cooling system pressure tested to 20 psi remove the spark plugs & see if any water/coolant comes out of the spark plug holes. You may have a cracked cylinder head or partially blown head gasket.

2003 hyundai elentra overheating and already did alot of standard procedures to fix the problem and still overheats. Car vurrently has 64k on it. Here is the history. Last year it overheated and changed...


The only other thing I can think of is maybe you put in the wrong kind of coolant? Not every type of coolant works in every car. Other than that, try head gasket sealer because if your head gasket is leaking, it can't be a big leak, otherwise you'd have problems right away.

5.3 liter Chevy engine #1 Cylinder not firing at idle


My opinion...

Year? Miles?

There's no way I'd dive into a "HEAD GASKET"
diagnosis without pressure testing the cooling
system and (wet/dry) COMPRESSION testing
the whole engine...

Even if it is a "HEAD GASKET"... the entire engine
might be ready for a REFRESH... and tossing a new
Head gasket into a TIRED ENGINE not insubstantial
(a lot of wasted time & money)...

Come back with some compression numbers...

but don't bother with any of this if your engine oil has water in it.

(in my opinion)

Have you had a block test done?A coolant system pressure test? I would check this and also if you have rear heat and air check at the rear of vehicle to make sure you are not wet.Where there is loss it must go somewhere.

I discovered water in my oil this morning on my 1999 blazer 4.3 v6 could this be the intake gasket?


It could be an intake manifold gasket causeing this...it could also be a head gasket and/or cracked cylinder head. You can pressure test the cooling system to check the intake gasket, and compression test the cylinders for head problems.. If you have had an overheating problem in the past the cylinder heads and gaskets would mostly likely be the problem....Removing the spark plugs will give you an indication on where the water is entering...the plug will be discolored.
Good luck..i hope this helps..please rate me a fixya.

My 96 Isuzu Rodeo does not indicate that it is overheating but the hoses connecting to the radiator swell up and look like they are ready to pop. Now, there is a really loud noise like a metal fan hitting...


sounds like you might have a head or head gasket problem, combustion pressure leaking into radiator/cooling system causing pressure build up (hose swelling) the noise could also be from this failure.
get engine warm so hoses swell, turn off engine remove spark plugs leave radiator cap on and pressure from cooling system as is(hoses swollen) wait 5-10 minutes crank over engine with plugs removed and keep clear of spark plug holes, put paper in front of spark plug holes if water comes out of spark plug hole or slight wetting of paper with water head or head gasket is at fault.
