Head gasket sealant

Hey Michael,
How/why do you think you have a blown gasket/cracked head??
....If you have a blown head gasket/cracked head you need to get it fixed ASAP.. Check your oil for cross contamination...( a light cream colored oil indicates water/antifreeze mixed with the oil).this WILL cause major damage if you continue to run the engine..(WATER is NOT a good engine lubricant!!!!) There are several "sealants" or radiator stop leak products... BUT ..cleaning these out of a coolant system is a NOT FUN!!.. Sorry.. trying to "patch" this will lead to more $$$$$ down the road!!

It depends what sort of stop leak you're talking about. There's different types.

Something for a leaking windshield rubber works by filling a gap and then becomes hard, similar to how bathroom sealant works.

An oil stop-leak works by penetrating and 'refurbishing' -swelling- dried gaskets and then hardening when it contacts the air on the outside of the engine block.

Some types of coolant sealant work by allowing particles to congregate/collect around a small hole in a radiator, blocking the hole. The particles harden due to the air/heat to form a plug. This type of sealant can also block your heater matrix, and they do not repair rubber hoses (hoses must be replaced if leaking).

A cylinder head sealant works by either depositing particles in a small crack in the head or gasket, or in the case of a modern head sealant, it uses polymers.

If you have a slight oil leak - slight - on an engine or auto box, try a sealant. If it's anything more than a slight weep, then gasket/seal replacement is the best option.

You need head gaskets.

All block sealers will work for MINOR seepage of head gaskets beyond that gasket replacement is suggested.

it depends upon what your problem is. If you have a badly blown head gasket then nothing will work, or if it is a small leak either into the water system or into the sump it could possibly work.So could you please give some more information about your problem.I hope this helpsregards

My personal experiences with gasket sealers for Head gaskets has been very poor due to the fact that it's difficult for the sealer to stick in the leak when there's so much combustion pressure trying to push the sealant out of the leak on one side and only about 17 psi of coolant pressure trying to keep it in from the other side. On both a 2.0L or a 2.4L engine I would suggest having the head removed and inspected and the gasket replaced....then your problem is fixed and done. Sealants may work for a while but I view them as a temporary band aid approach at best. If you have over 100,000 miles on the engine and haven't yet replaced the timing belt then it would be a good time to do that also as a worn timing belt can cause some pretty severe engine damage should it fail. Hope this helps and good luck!

head gaket sealants seldom work, the reason is the problem is to far gone and the blow out to large to seal

Probably around $1000.00. It's a rather involved job.

Check your engine oil...you know...do an oil change....this way you are only paying for oil....if you have a blown head gasket....don't worry about the filter.

you have too pull the head anyway so put a new gasket in their less than 30.00
