I have a beater with a heater that blew a head gasket. It's a 1998 Ford Expedition with a 4.6 Liter, just hit 117,000 miles. These trucks are great for hauling and oddball jobs. To replace the head gasket was going to either cost $800 + at the shop or do it myself and spend hours in the garage. I am sure as you can imagine this truck is not really worth that kind of money or time. To be honest I was getting ready to let her go to the junkyard. I started digging around for low mile trucks and unless you are dropping around $10K you are going to get anything worthwhile.

I had heard a few people a long time ago talk about a product like this and did some online searching on head gasket repair products. I stumbled across the Bar's Leak Professional. It does have mixed reviews but I thought for $34 it was worth a try.

In my research, I did find our that people used it and grenaded the motor. Come to find out if the head gasket is allowing coolant into your oil system this might not be the fix you are looking for. If the Sodium Silicate gets in by your piston and combustion chambers it is going to create huge problems for your engine. The military used Sodium Silicate to destroy motors by putting it in with the oil. So double-check your engine oil before using this. If your oil looks like creamy coffee I would find other options.

I put together a little video showing how I installed the Bar's Leak. It doesn't get any easier than this. Best $34 I have spent in some time.
