I POSTED A PROBLEM WITH MY CAR I TOOK IT TO PEPBOY'S AND THEY TOLD ME THAT IT WAS THE HEADS BUT THE CAR SHOWS NO SIGNS OF THEM GOING BAD TOOK IT TO ANOTHER MACHANIC AND HE SAID IT SHOW THAT IT IS RUNNIG GOOD AND NO SIGNS. IT DOES NOT MISS FIRE OR HEAT UP IT STAYS AT THE RIGHT TEMP 190 TO 210 BUT IT NEED WATER EVERYDAY ABOUT A 20 OZ CUP OFF WATER. THE COOLANT RECOVERY TANK IS BROKE ON THE TOP WERE THE BATTERY SITS. THE MACHANIC TOLD ME IT IS NORMAL NOT THE SEE WATER IN THE RADIATOR BUT WHEN I TURN ON THE CAR THE WATER WILL RISE TO THE TOP. I GUESS THE ONLY WAY I WILL KNOW IF I LET SOME MACHANIC TAKE THE HEADS OFF AND GET THEM CHECKED.

CAN YOU GET A BAD READ FROM A PRESSURE TEST AND DOING THE DYE THING IN THE RADIATOR. MY CAR DOES NOT SHOW SIGNS THAT THE HEADS ARE CRACKED IT DOES NOT SMOKE,MISFIRE,WATER IN OIL,TEMP STAYED AT 190 TO 210. THE ONLY TEST THEY HAVE NOT DID IT THE PRESSURE AND REMOVE THE SPARK PLUG ONE OR REMOVE THE HEADS AND GET THEM TESTED EVEN IF THEY GET TAKEN OFF THE GASKETS NEED TO BE REPLACED RIGHT OR WRONG NEED HELP

Replying to: trail03 (Nov 11, 2009 2:07 am) If a valve is bad and not sealing, or the rings on the piston are bad, or the head gasket is leaking, then the cylinder pressure will be lower than it is supposed to be.

Replying to: kiawah (Nov 11, 2009 5:42 am) So, if your left cylinder bank, for instance, reads 150, 155, 145, 150, that's healthy. But if the right bank reads 150 90 90 150, then you almost certainly have a break in the head gasket between those two cylinders. The reason I say "sometimes" is because head gaskets can break or deform in different places on the head. The break or defect doesn't ALWAYS lead to low compression, or to water in the oil. Sometimes you can get exhaust gases in the coolant, for instance. In that latter case, you can chemically test your coolant for the presence of combustion gases. Tracking down a head gasket leak is a science. Taking off the heads to see if there is a leak is like sawing off the top of your head to see if there's a tumor. There are more preliminary methods. |
