Paula Seller: my heater core is bypassed is it gonna affect it that i cant turn on heater
Keeper Of The Reaper: mute this crap
Eric S.: I used this stuff on a 1992 BMW 525i. It worked well at first, but after about 800 miles started losing compression again. Then it got much worse as the sealant started getting cooked to my exhaust valves. All this is to say that Blue Devil is a band-aid, not a permanent fix. If you need to use it, still plan on getting your headgasket replaced. You could do real damage to the car if you try to ride this stuff too long.
Jose Peixoto: 65 dollars???? you bought a blue devil?!!! you got robbed; it is just SODIUM SILICATE; worth 1 or 2 dollars; it converts to glass-like upon reaching 100-105 deg. C; request the help of the Google guys,read for yourself....
Leo D: I'm going to try this on a 400$ 1997 Honda prelude, oil n coolant are mixing, I'll keep u guys posted. oil looks like coffee with cream.
Lucas Winders: The song was perfect!
watchingitallhere: Devil music*
Benjamin Morgan: \m/
Makas Arachnid8: i think for a quik fix its ok but id rather fix it the right way ..and never have to worrie about it ever again.. but what ever works
Jasmine Mendoza: I don't have a radiator cap. which is the top hose?
CIA Assassin: bar's pellets work faster and only cost $5. fixed my head gasket leak 6 years ago and sold the car just a few days ago. never used a drop of coolant.
Art Hicks: crap i poured that liquid diarrhea and my Honda Accord had a breach in a few cylinders. .Green apple slush looking crap was swimming in chambers
Bungerism: This stuff is garbage,It's intended as an emergency repair to the nearest auto shop,NOT permanent repair,Do your research B4 you consider counting on that...Clogs most coolant flow ports and it takes @ least 3 engine flushes to get removed from your cooling system,Speaking from experience..........
dennis bryan: ticking time bomb
Ryan Pentz: has your truck had any problems with the head gasket since this ? please help my car has a bad head gasket
Darksyne: Did you remove the thermostat?
Cynthia Joy Strobel: I got the 32 oz bottle of BD Head Gasket Sealer for $49.95 at the O'Reilly's Auto parts store in Napa CA. Waiting for my mechanic to fit me in to do the whole process. My exhaust is thick white "smoke". Starting issues still after replacing the throttle body and MAF sensor twice with new ones twice with used ones first. Coolant level dropping still but less than before. Now we'll see if Blue Devil fixes the head gasket apparent leak.
slvrserfr: Adding this stuff without coolant as they instruct is asking to fry your piston rings. The material is weak and hardens with a durability of cake icing. Total waste of money.
CLF Franklin: worked for me over 9 different cars!i love this crap,made me a small fortune.
eeeno: Exhaust gases are different between a cold and warm engine and during winter it's just normal to see the car emitting white smoke when not totally warmed up. This is just a bandage, nothing more. It could do much more damage as it clogs the small water passages and the engine would fail later on and is going to need more extensive repair.
