    I fixed a truck(not ih) that some one used stop leak in instead of fixing it right:censored:. I've ran across this more times than not with this type of product, bad stuff. If you must temp patch a cooling system use an egg or black pepper, works as good and doesn't do this to you head gasket. The stop leak was only in this engine for about a year too.

    I'd hold out for more scientific proof as least for IH motors. (Don't we run steel gaskets?) As I've put more then my fair share of that stuff in my truck and it has been running as a daily driver for over 5 years since I know I last put some in. Without a single issue related to heads or other coolant areas. I do have some leaks under the intake manifold but it's probably due to age anyways. (The welch? plugs)

    Just my observation so maybe I'm just a lucky one.

    That damage was probably already done, Stopleak or not
    I like the egg trick better than Bar's Leak

    I am with IH wild
    I have used the stuff many times in my younger days. Never had a problem.
    That being said. I think that fixing it right is a much better idea

    I've seen that on aluminum head and cast iron blocks. The Bars leak drops out in the engine block near the freeze plugs. I open a few motors and wash a cup or two of that stuff out. If the radiator leaks and your not going to fix it, just remove the radiator cap, then you will have no pressure

    Since coolant and therefore stop leak couldn't touch that gasket where it blew out I can't blame the stop leak. That damage is more likely from overheating and detonation or warped head. Most people don't check coolant until the engine overheats then top it off, find a leak and add stop leak. Un fortunately the damage is usually done by then.

    I never said it happens to EVERY engine, but it does happen to a lot of them. This gasket blow out had nothing to do with warped head or over heating. I ended up replacing the rad, heater core and water pump. The water pump had the fins eaten off by the stuff and the heater core was plugged up from the stop leak. I worked in a shop for 18-20 years, this problem is common with stop leak products. You can use it if you want, but it's a crap shoot if you do.

    This is what I was thinking. That erosion isn't adjacent to any cooling passages from what I can tell. I don't think coolant ever touched it there.

    I think the leak caused the problem, and the improper fix did nothing for it.

    In other words, yes by sequence of events, you could argue that the stop leak did it. Or, you could argue that the sequence of events was started by a cooling problem that was never fixed.

    There are Five basic types of stop leak {tell me if you know others, please}

    1. Bar's Leaks black rat turds in liquid in a jar. Maybe it is in a jar because it will eat it's way out of a can?

    2. Bar's Leaks large 'pills' that just fit through the radiator cap opening. They look like horse feed. They are my favorite.

    3. AlumaSeal and the like. Powdered aluminum with some chemistry to stick together. My radiator guy doesn't like this stuff.

    4.Crystalline glass block sealer. I have no experience with this stuff nor any anectodal stories either. Anybody?

    [5] eggs, black pepper, sawdust, etc homebrews. If it will get you home, why not?

    Bill, I generally dump Bar's Leaks horse pills in there to get the beast home then pull the radiator and haul it to the radiator man.

    Leave it to you to think of actually REPAIRING it!!

    Your crystalline glass sealer or "water glass" is sodium silicate or what was commonly known as "egg keep" for preserving whole chicken eggs. Used to be available at drug stores. Like many old time remedies, it works best if the system is unpressurized. If you drop pieces of crystallized minerals into egg keep they will slowly grow into weird and grotesque shapes-more than you wanted to know I know!:wrenching:
