Are you sure the whole system is like the header tank. You might find the rest not as bad.

It's funny the same stuff they use to kill CARS engines is a miracle head gasket cure.

Clearly, it is not a miracle head gasket cure.

Yes, I am still alive, and still in the Rover parts business.
Text me for greatest likelihood of finding me.

So, I flushed it out this morning, gallons and gallons, this way and that way. The header tank was definitely the worst. Cleaned the header tank and thermostat really well. I think that a lot of gel was on the thermostat, not opening it to open up much, thus the overheating.
I ran the car a few miles, now - everything seems good. Just got the "swooshing" sound in the interior, so the heating has likely got air pockets.

It appears to be like most things, if you do not read the instructions you run the risk of stuffing things up.

I've researched the web to find that various car companies use liquid seal products as a preventive mesure for coolant leaks, GM is a big example they use Barr leaks.

My external leak is slowing dramatically after I drained, bled and added 1/4 bottle of pour and go. Looks like the "shit that doesn't work" is going to buy me some time. Here is a good read, funny how Bar's has been in business since 1947 making something that doesn't work.

Buy time, correct, fix the issue, NO. Nobody said it wasn't going to work. You could throw a hand full of saw dust in there and eventually it will stop the leaking too.

My previous experience with stop leak stuff was as a temp measure to get you down the road far enough to get it fixed. As a crazy teen, I burnt up a couple motors due to heat. The second time was a stop leak product gone bad. Clogged up the thermostat and overheated the engine. Since then, no way..

The anxiety of knowing that some day the temp gauge is going to spike without notice, a hot water mixture of some sort will be try to escape out the overflow and your block will get twice as hot as it should... and BAM your worse off than before.

I am glad it is no longer leaking, I would't use it.

The issue with me is that it was just small enough of a leak to piss me off. On top of that a gasket that's only 16K old. Dave, I used the pour n go. I'm not sure if I'm out of the woods yet. I'm not seeing anything on the garage floor anymore and I can't identify the leak on the engine block. It may I have stopped completely but it's too early to tell.

Word games. Let's put it in perspective here. These head gaskets might last 40-80-100K new from the factory. My new set lasted only 16K. There are cars on the road with 200-300K on the originals. So IMO if it sealer will fix the problem for any duration it is a permanent fix giving the very early failure rate of these head gaskets.

Pour and go, but what brand? BlueDevil? Bar's Leak?
I think once it seals it will last. I think it' a good alternative if the seals work for small leaks like ours.

Thanks Brian. I think the other issue using the product is the way our cooling system is set up, pouring it in the expansion tank does not get it to flow fast as it needs to to the block. There has to be away of pouring it so it goes to the block before it passes throught the radiator or heater core.
