Thumbs down Heads Crack leak?

I think my right side head is cracked or something

I had the headgasket changed and the compression is 155 while all the other cylinders are at 180. This was Before and after the bad headgasket change! The headgasket appeared normal when It was changed

i found some drops of water on the spark plug when i removed it so i know WATER is getting into only 1 of the cylinders. The center one on this 4.0 v6 on the right head.

Is it possible that my head cracked?

Im going to change the gasket again but this time i think i might put a new head on too!

any suggestions?

Re: Heads Crack leak?

With a suspected blown head gasket between a cylinder and the water jacket, water will get into the cylinder when the cooling system is still pressurized after you shut the engine off. On the other hand when you have the engine running, compression will leak out into the water jacket. So, try this. Remove the radiator cap and run the engine. Check for any persisten bubbling. If you notice any bubbling, then your suspicion of a blown gasket is correct. Also did you say that your compression reading was 155 on one cylinder while the rest is at 180? If you decide to take the head off, have them maganflux it for crack/s.

Suspected blown head gasket between a cylinder and the water jacket!

Yeah something like this is happening!

I was doing some reading on other problems people have experienced and I have the same case as this story I just read. I must have a HIGH PRESSURE Leak. because the car will run normal for 10 minutes or so and then when the pressure builds up the temperature will sore and the leak occures.

Will a crack in the lower intake cause a engine to overheat? i know if the lower intake leaks the water can enter the cylinder and be burned with the fuel and it is doing that!

Re: Heads Crack leak?

after I turned off the car I went to the motor to listen, I heard some water leak and then sizzle into steam while putting my ear close to the lower intake close to the one cylinder with 155

Re: Heads Crack leak?

155 is not bad for an older engine IF your other cylinders were also reading plus or minus 10 PSI. However I believe you said that the other cylinders were reading around 180. In any event the head has to come out.
