BlueDevil Head Gasket Sealer

Do “pour-in” sealers like BlueDevil Head Gasket Sealer work?

BlueDevil Head Gasket Sealer is an aftermarket quick fix for leaky head gaskets that you pour into the radiator. It costs around $60.00 a bottle (you might find it cheaper if you look online or at your local supercenter).

Consider BlueDevil Head Gasket Sealer if you need a less-expensive fix than a full rebuild job.
BD Head Gasket Sealer can help you avoid or delay a costly rebuild.

I don’t like fix-it-in-a-can solutions; but they can be worth a try compared to a $2500.00 rebuild. It’s not like Bar’s One Seal Stop Leak (which is a tenth of the price); but does the same thing except much better, in my experience. Still, I am reluctant to try this stuff except as a last resort to avoid a rebuild and a big bill.

Buyer beware, and your mileage may vary, so research carefully before you decide to go this route for your head gasket fix. A treatment is said to last eight months.

It is an inexpensive way to fix minor cracks in your head gasket and other critical components of the engine cooling system. However, if you have a more seriously damaged head gasket, it will likely not be a satisfactory fix for you. That’s because it does not have any fibers or particulates that would be needed to fill larger gaps.

Some reviews or write-ups claim BD can provide a permanent leak repair. That may not be true. The product can be safely used on gas and diesel engines, regardless of the size/number of cylinders.

It can take 30 to 45 days to work. The active ingredient in this and other similar products is said to be the same substance.

Never use that junk in all aluminum engines as it wrecks them. Engine rebuilders and machine shops often won’t accept blocks or heads gummed up with block sealer and you’ll have to pay a core charge. Some people get away with it for a little while and then while accelerating on a highway the engine overheats and leaves you stranded. Driving a vehicle that overheats will damage more than just the engine. Often you’ll burn up the automatic transmission fluid and then the trans.

Used blue devil on 04 Dodge Durango for blown head gasket, been 2 years still running great!!!!
