Anyone with any vehicle have any experience with radiator added head gasket repair addatives? Looking for opinions on specific brands. Water is leaking into oil and crankcase not into the cylinders.Thanks!

They don't workif the leak is large. There is not even a good chance that they will work if the leak is small. Find the problem and repair it--that's the best bet.

i would suspect head gasket - year, make model and engine? bfree is right there's no cure in a can most myay get you home but the problem needs to be repaired.

whitetailjedi,

This is your second posting for the same problem. For our answers check your first posting.

replacing the cylinde head is the best and longest lasting repair for this problem.

Stopping compression from leaking out of the combustion chamber is without a doubt the hardest to seal. Stopping coolant from entering the crankcase
is not as hard but there is no guarantee that this will happen no matter what you use. I'm not a big fan of plugging companies but I do like BG Cooling System Sealer. Blue Devil is supposed to work and is also supposed to be guaranteed. Good luck.

Customer has yet to respond. Original post is from 6/8/2011.

we needed the year, make, and model? Hope ya' got it going.

Caution tech to using these products as a crutch or alternative to good diagnostic procedures. I see more vehicles than I should where this "stop-leak type" of stuff has been used, hoping it would perform some car repair miracle.

They can be a problem (stopping up radiators and heater cores etc.) but some manufactures swear by them ie. Caddilac and their pellets. If you can't build it right just build it and figure out the flaws later. LOL

Still not a single response from the original poster. Goes back to 6/8/2011.

Hopefully the poster read these and decided to get it repaired the proper way.

Hopefully they read this post.

Of course they read it, doesn't everyone?
There is a lot of good info here.
