i saw that at Advance Autoparts.. do you think it actualy works? it sounds like it would. i cant remember what all the bottle said. but it was $19..i'm thinking of trying it on my 87 5.0 that blows white smoke

moroso ceramic block sealer is probably your best bet, but even if THAT worked its a used car salesman crap fix gimmick

how do i test to see if ia blown head gasket? open the radiator cap and look for bubbles?


could a vacuum leak cause thick white smoke that burns my eyes? (it used to be black until i took the h pipe off..so i figured out the pipes was turning the smoke black)

The best way to tell would be to do a compression check or a cylinder leakdown test.

you can purchase a kit called a block tester..it's a flask with a squeeze ball and solution that tests for hydrocarbons in the cooling system and can be purchased at places like napa

im not a big fan of these products but i have a friend who used this stuff on his 93 SHO and it was in a blue bottle from autozone and it was like $50.00. its been almost a year and no issues.

it will not work on a 5.0.

All of the 5.0's ive ran into, had the headgaskets blow in between two cylinders.

ok guys i am an employee of advance auto parts and i am currently going to school to become a mechanic

this stuff just like all other radiator stop leaks look for a "leak" the only problem is it sees those coolant passage holes in the headgasket(the really small ones over the coolant passages) as a leak and clogges them up making cooling problems

and yes we have ALOT of used car lots buying stop leaks of all kinds through our commercial dept. for the cars they are selling

I work at AutoZone and we have a product called Blue Devil and it's 49.99. It works awesome. I used it on a turbo 2.0 sohc neon and it worked for over 1 year and then i sold it.

If you just want a cheap fix then you could try the stop leak, but those products are just bandades.
mom had a pontiac grand am once and it kept overheating. One day she called me and said the temp guage was pegged (280 or something). I told her to just keep driving it. She did and the car never overheated or leaked coolant again!! Probobly melted the head gasket, but who cares cause it was a pontiac. I figuredI would just share this cause it's pretty funny, butPlease, for the love of god, don't do this to your mustang!!!!!
