I was watching a couple of shows the other day when it talked about if you had a head gasket failure to use Bar's Leak products. Has anyone used any and do they work? I haven't had the pleasure of having a head gasket fail yet, (knock-on-wood) but it says that you can get the repair or fix additive and it should help. Also they sell a Rear main seal repair additive as well. Since I have a little leak from behind the engine, just wondering about adding something, but I don't want to hurt the engine.
