How to change blown head gasket

if you did not have the head gasket changed
...everything you did is a waste of time. you never corrected the problem of a leaking head gasket.

Dear David ,maybe you can fix it by some special powders like (WONDER SEAL) but it isn't a logical way for long time . actually for winter because of antifreeze liquids. (they release wonder seal) I always prefer rational and main way with original parts .this is my experience : Don't choose cheaps .they are most expensive .

You need to flush the cooling system if you are going to try a sealant. I have used ceramic sealer several times with mixed results. (about 50% of the time) I would not use steel seal. Unless you have a great deal of experience I would not recommend you try this repair. You need special tools to perform the repairs. High skill level+$ for special tools

Water in the oil can only mean a few things: a blown head gasket, intake manifold gasket (on some engines), a cracked/broken cylinder head, or a cracked/broken cylinder wall in the engine block.

In any of these cases, it is going to require major engine repair to fix it. There may be moderate to severe damage to the engine bearings (cam and crank bearings) due to the water in the oil. I would recommend TOWING it to a professional repair shop to get an evaluation of the damage. You may be able to fix it with a head gasket replacement and an oil change, or you may have to replace the entire engine. DO NOT OPERATE THE ENGINE OR TRY TO DRIVE THE VEHICLE. This will only GAURANTEE that you will need to replace the entire engine!

sounds like a head gasket blown, when engine is cold, remove rad cap and make sure rad is full, start engine and see if bubbles are pushed out of the rad filler spout, a blown head gasket will pressure up your coolant system, was the rad changed because of overheating, do you have the thermostat installed wrong? the sensor side toward engine. if head gasket is ok, next you could check your rad cap, is the gasket ok? can you check if it holds the required pressure. might need replacing. also if you could pressure test the coolant system and see if it holds.

I would not recommend doing this work at home. It requires specialized tools, such as a torque wrench, piston ring compressor,and a good manual for torque sequence and values. Furthermore, most blown gasket mishaps require bringing the head surface back to flat and true.

The only way possible: remove the cylinder head and replace it. And do it quickly because a blown head gasket can seriously damage an engine if left unfixed.
This is a serious job, which requires mechanical knowledge and some special tools - a torque wrench is mandatory.

This is a major overhaul requiring special tools and expertise.

FIRST IF IT IS A BLOWN HEAD GASKET IT IS RIGHT COMPLICATED IF YOU DO NOT KNOW WHAT TO DO...ME PERSONALLY.. YES I WOULD DEFINATELY GET THE FULL GASKET KIT..DON'T EVER DO ONE HEAD DO BOTH.. HAVE HEADS ONCE OF ENGINE TAKEN TO MACHINE SHOP TO GIVE FULL BATTERY OF TEST...

Yes, driving around with a blown headgasket is BADDDD....

If you've never replaced a headgasket before then I would suggest that you not try it without proper supervision and help.
On a v8 when you replace one headgasket you replace the other as well. The gasket kit comes as a set of 2 headgaskets and all other gaskets and o-rings that will need to be replaced. You will need an array of tools to accomplish the mission - some hand tools and some specialty tools for dismantling the cylinder head.
I'm really not trying to scare you off but this is NO SMALL JOB. It will require patience and it will require tools and prior knowledge - so get the HAYNES RePAIR manual for the car and read up if you decide to go for it. I did the headgastets on my Acura Legend v6 - and what should have taken 30 hours start to finish took about 55.
Good Luck and Happy Motoring!!!!!!!
