Thermagasket?

[9dawgs]

I posted in the "what did you do with your van" section about replacing my water pump due to a green puddle on the driveway under my van about center left. Well, I took everything off to get to the pump (ie; fan shroud, fan, belt pulley, etc) and low and behold the pump was not leaking. Since the 4.3 sits back in a cave, I grabbed my trusty flashlight and began the search for the leak. This is a slow but steady drip so it wouldn't be hard to find now that everything was out of the way. I found it...the drivers side cylinderhead is leaking where it mates up to the block. Fortunately I don't have anything leaking into the cylinderhead.

This is an expensive fix that I'm not prepared at the moment to do so I was wondering if anyone has heard of or used Thermagasket? I spoke with a friend of mine who is a mechanic and he suggested I try it until I can pull the engine and fix it myself.

I went ahead and ordered the kit along with a flush kit. I'll post on here how good it works but it looks like it will do the trick. I was just wondering if anyone has used it here.

Never heard of it, is this something you are supposed to add to your coolant? too bad its not an intake leak a bit of a pita but certainly not expensive.

Even if it's head gaskets it's not all that expensive. A bit time consuming though. I've never heard of Thermagasket. Let us know how it works.

I've heard of thermagasket. It is simular to bars-leak in the way it works.
So if you don't care to much for your motor, radiator, or you are planning on selling it right away then go ahead and use it.
Personally, myself I would pull the head off and fix it properly, you are going to have to eventually anyway.
Bars-leak, thermagasket, seals-all, are all just temporary fixes to a problem that will re-occur.

Moroso sold at one time a ceramic sealer.It's been yrs since I looked at that so I am not sure if they still do.I do remember it came with a guarantee.It is not in any way through I agree with a fix in a bottle over fixing it the right way.
