Strait up doesn't work. Engine ran great for a week.... Then went strait back to leaking coolant into the oil.

A very good product, very specific, not for gaseous exhaust in coolant fix. Go different route
I have to say this one put up a good fight but it definitely does not fix the cylinder breach, if you have gas bubbles coming up in your coolant do not buy this.

Non-clogging, works for small leak
Sealed a small head gasket leak after just a few miles of driving. Did not clog anything.

Not sure yet but may be best approach to fixing problem
Have not tried it yet but being a waterbased coatings chemist I think it may be the best product available to accomplish the job on engines with small head gasket leak. The price is too high thou for the risk!

Works great
Easy to use. No clogging. Works great. I was seeing a lot of white smoke and having to top off my antifreeze before using it. Now there's no smoke and my antifreeze hasn't had to be topped off since. I wish it was cheaper, but it's a lot cheaper and easier than replacing a head gasket.
