Head gasket liquid repair.

I know if a vehicle has a blown head gasket it should be replaced. However, I am wondering if anyone has ever used the products that allegedly seal the leak without clogging the engine or causing other issues such as "Steel Seal".

 

I haven't tried them, but I would only use them in a vehicle that I care nothing about.

 

I heard this works excellent

 

I had a Chrysler LeBaron given to me with a blown head gasket or cracked head (didn't care to investigate). I can't remember the brand I used but it was a 2 part system. Put that in following the instructions, then I sold the car to a friend of mine for his brother's first car, with him knowing the possible issue. Kid drove it around for 4 or 5 months with no issues until he wrecked it, so I can't speak to the longevity, but it did work on that car for that long.

 

Give some time Ill see if I can get the right name of the sealer its expensive like 80$ plus.. This stuff is liquid does not block any coolant passages.

 

have 2 things at work . never used either .
Blue Devil brand . part#00209 . pour n go head gasket sealer .
Iron Tite brand . part#9120-16 . ceramic motor seal . sez permanently seals engine coolant systems . not compatible with antifreeze . have to remove antifreeze and fill system with water to use .

 

Not a head gasket, but I had an intake manifold gasket that leaked coolant horribly (Chevy V6... they all do that). Have to completely disassemble the transverse-mount engine to work on it, so I just dumped in the old bars radiator stop leak into the radiator. It worked for about 6 month. Put the stuff in every 3-6 months until I got rid of it 100 k miles later. Never did have to pull the intake. I would have fixed it right if I cared much about the car, but it was a beater.

 

Strictly old school. That or horse manure.

 

What kind of vehicle? Why do you think the head gasket is blown?

 

I had a head gasket leaking coolant to the outside of the engine one time and put in a bottle of Bar's leaks and drove it for 40,000 miles before I sold it. I never had to add any coolant after the treatment. My mechanic who I have been using since the mid 80's actually recommended it.

Vehicle was a 1978 Toyota with a 20R.

 

Has anyone ever used the AC/Delco coolant tabs?

 

Has anyone ever used the AC/Delco coolant tabs?

Those were big at a Caddy dealership I work at in the mid 80's. That was part of the standard warranty 6 month check-up. Seemed kind of odd to put a bandaid on a brand new Cadillac. IIRC, there was 2 tablets (looked like alka-seltzer) and a smallish tube of aluminum powder stuff.

 

I don't know if GM still does it, but back in the 80's, they put the seal tabs in at the factory. A new 1988 Delta 88 with 12 miles on the odometer was towed in because the engine quit. It turns out, it overheated and the customer drove it until the engine seized. When I removed the radiator cap, there was no coolant, just seal tabs in the radiator. The service manager informed me that I prepped the new car and that it was my fault for not checking the coolant level. At the time, GM cut the PDI times way down. There was a service bulletin stating that you no longer needed to check any fluid level that didn't have a dipstick. GM later came out with a bulletin stating that we needed to disregard the previous bulletin. Apparently, GM ate a lot of engines, front and rear differentials and transfer cases.
