My personal opinion is that the wording "head gasket" sounds complicated. When you say "engine block seal" it will make a little more since as to what you are actually dealing with and is no different. To answer your question, YES there is a temporary fix for a blown head gasket and it cost anywhere from $10.00-$65.00. It is called BARS Seal, BARS leak, Bars stop leak, and there are some other brands, but BARS Seal has always worked for me. It is a thick liquid substance that you pour into your radiator and when you follow the directions exactly, it works on any brand or size engine with a blown head gasket. In most cases this is temporary even though it may say "permanent" don't get your hopes up. I do, currently, own a 1995 V6 Toyota 4runner 4x4 sr5 that blew it's head gasket, back in 2001, and runs like a top, today, after adding BARS Seal 1 time, 9.5 years ago.
If there are no visible leaks....a blown head gasket.
Not likely.... I'd never use anything "temporary" on a head gasket.
replace head gasket
Any parts store can provide you with the correct gasket.
It is either an intake gasket, or head gasket most likely...bring it in to a mechanic.
$2200 is what I spent but it was head gasket and intake gaskets.
Blown head gasket, cracked head, or cracked block.
you should never use a sealant on a head gasket as that is only a temporary fix in an emergency situation. The only permanent fix is to replace the gasket.
IMO, this is only a temporary emergency fix. It will not permanently fix the problem. You will need a new head gasket.
It may work as an emergency temporary repair but the only permanent repair is to replace the head gasket.
The gasket is between the head and the intake.
No, that is, at best, a temporary fix. The only permanent repair is to replace the gasket.
