Need to use a compression tester - screwed into the holes of the REMOVED spark plugs. Then get a Haynes manual for the pressure values for your car.
a good indication that you need to do that is if you have white smoke coming from the exhaust, or if your oil looks milky.
white smoke is caused by antifreeze leaking through the head gasket into the cylinder. when it burns it makes white smoke. if your oil looks milky it is because it has coolant in it.
Drug and Alcohol programs do work, but only if the person is willing to make a change and commit fully to the program. Many people fail because they have not fully committed to program. Of you are interested in a specific program, you should call up a coordinator from the program and ask them for their success rate, and many do not make this information public.
You may not see anything on the gasket. Usually a head gasket "blows" because of overheating that causes the head to warp. A gasket can be bad but there should be a visable break very often in the ring around the cylinder.
There are several possible indications of a blown head gasket: If the head gasket is blown between adjacent cylinders there will be poor or no compression in either cylinder. Poor compression in any cylinder can be caused by a blown head gasket. That condition can also be caused by a burned valve or piston. Coolant in the crank case can be caused by a blown head gasket. Compression in the coolant can be caused by a blown head gasket. An engine with a blown head gasket usually loses performance and runs poorly or not at all.
It does not matter. If one is blown on a V6 or V8 then you need to replace them both.
I know for a 93 BMW 325is 2.5L DOHC 6chy. You might as well just go a head and buy the head gasket set it runs about 200$ at autozone. It comes with valve cover gasket, valve stem seals, and head gasket. But its also recommended to replace the cylinder head bolts also.
Besides water in the oil, you will have little to no compression on the cylinder(s) in the area where the gasket is blown.
14 hours if you know what ur doing
I usually hook up a pressure tester to the radiator for about 20 minutes or so...pull the spark plugs out then crank over the motor. If the head gasket is blown then antifreeze will usually have gotten into the cylinder that has the blown section of the head gasket. When you crank over the engine then antifreeze will squirt out of the cylinder with the antifreeze in it. Also smell the exhaust.. can you smell antifreeze in the exhaust. Is there white smoke coming out of the tailpipe ? That is also a sign of a bad head gasket. Finally. Does the car overheat after a short period of driving ? Yet another sign of a bad head gasket.
If you see a lot of white smoke coming out of the muffler , that is the sign.
I don't know which one was at fault but I replaced the head, the head gasket, and the intake manifold gasket.
what are you asking here? PLease be more specific ...like - how do I know if my head gasket is blown, or what do I do about a blown head gasket ......
Head gastket located between the engine block and the cylinder head. Going rate around $400 at a local repair shop. The gasket is cheap however the replacement is labor intensive. If you don't know where the head gasket is you definitely want it to be replaced by a professional. Saludos,KW
you will either see coolant around where the head sits on the block,or,white smoke coming out of the tailpipe. at that point coolant will be getting past the head gasket and leak into the cylinder or cylinders. also check your spark plugs and do a test to check for exhaust gases coming out of your radiator.
