Especially when you use it improperly.

Wasn't my engine. I guarantee they put it in let it run for 3 minutes and shut it off.

Are you sure that is radiator sealer or sludge caused by mixing wrong types of antifreeze together? I just did a head gasket job on a car that had that crap in the radiator, head and manifold passages. I questioned the owner about stop leak and he claimed he didn't use it. Found out he had changed hoses about a year ago and the parts store had told him he needed Dexcool coolant. The car was old enough that it had regular ethylene glycol in it. They don't mix!! The sludge looked the same. Had that orangish tint to it.

I don't think this was Dexcool sludge. I spent some quality time filling the block with hot water and blowing it out with compressed air. It was all solid chinks like this no congealed mess.

The only stop leak I have ever used was the aluminum powder. Well, that's kind of a fib... Once, in a pinch, I used ground pepper. it actually held very well. About 6 months.

I have never had any luck with Radiator seal. A friend swears by BARS Leak but not me....the way my luck is....better off to just pony up the $ for new Rad. If its gonna let loose on me it will do it at the worse poss time.......

I had a 1964 Ford Falcon and the radiator leaked. I had it worked on in a radiator repair shop and it still leaked. I put stop leak in it, and it still leaked. Finally I put in a can of Black Pepper and it quit leaking! :thumbs:

I've added that aluma-seal stuff at about 150k in a small block Chevy van that I bought from my BIL (dealer told him it was a cracked head) and gonna be expensive. I was gonna put another engine in it but thought "oh what the heck lets try this stuff...each winter I would add some fresh anti-freeze and another tube of the aluma-seal stuff, well this last summer at 442K when the seat belts were needed just to keep the kids from falling thru the floorboards and the tranny (3rd one) was on its way out again I actually junked a vehicle. So I'm thinking the alum powder stuff works pretty good.

I only use alumaseal. Bars leak will plug up heater cores very quickly. I only use alumaseal as a "bandaid"until I get time to properly fix the leak.

The little tubes of Silver Seal have saved my bacon several times over the years without any adverse problems. It's the only stop leak I keep on hand in case of an emergency.
