Nick Doe: If it didn't last, take the video down so others don't do this.
Rusiputki: The people who find this stuff to crack is because it's not very tolerant
Stuckneutral: I bought some QuikSteel to fix my crack and it said 2400F degrees right on
the package, but it only lasted about 1200 miles before coming out. Luckily
I had ordered a new manifold for my 2001 Civic because I discovered right
after repairing the visible crack in front that it was also cracked in the
back as well.
Toonses: Amazing stuff for poor people which the majority of us are.

Neil dela cruz: I've been trying to pass the smog test. I had my o2 sensors changed and my
CO passed the 15mph test but not the 25mph. The mechanic suspects that the
teeny tiny crack on my manifold may be throwing the o2 sensor off therefore
failing my emissions test. I just bought this quiksteel extreme...do you
think it would help pass my smog? ( i hope it does. it's like $400-$500 to
replace the manifold )
David L: Shyflirt1 was your check engine light on with the crack and could you
recommend a replacement manifold/cat
Brandon West: how well has this held up?
kevin ledford: i used this on my 2000 mustang, passenger manifold as a temp fix until i
can afford the 100 for a new manifold, has held up for 6 weeks so far, I
used sanding wheel and wire brush on a dremel, degreased and applied it, i
also used some aluminum exhaust tape and wrapped it good, just as extra
measure, The key is to sand and clean good and let it cure 12-24 hours
Soloman36: 97 Honda Civic LX..... same crack as in the video. This was a very
temporary fix - lasted about 1month... So, took the car to a muffler shop
and they just welded the crack. I believe they used a Miller welding
machine. I took the heat shield off and prep the area as in the video
before taking it to the muffler shop. The charged me $10 and it took less
than 5 minutes to weld. Check Engine Light has been off for several months
now. I would recommend anyone to just take it to a muffler shop instead of
wasting time and money trying this solution. Be sure to prep the area that
needs to be weld.
Jason Plante: Is this product waterproof once it cures? I need to use something in the
engine block with a lot of coolant flowing past it and I don't want it to
deteriorate due to the fluid.
Soloman36: Hi.... I just wanted to say that this videe was very helpful. It cleared my
CEL code. I had the O2 sensor replaced but CEL was still on because of the
crack on the manifold. After following your procedure and allowing the
quicksteel to cure properly also clearing the code. The CEL has gone away.
It's been ~ 1500 miles now and not CEL... Thanks for the video.
shyflirt1: I really don't know. You would need to get it extremely clean of oil before
applying. I am not sure if the oil would degrade the Thermosteel after the
fact. You might be able to just get it welded. If the oilpan on your car is
easy to remove (without removing a bunch of other stuff), you might just
rub504: you think i can use this to repair my oil pan? the crack is really close to
the down pipe.
shyflirt1: Gotta love a Dremel tool! It did work. I had read that the stuff would chip
off, but mine didn't. It was on there until I replaced the
manifold/catalytic converter. The crack had already damaged the O2 sensors
which then messed up the catalytic converter. This fi did at least help
prevent further damage until I replaced the unit. And it did help my car
run smoother and quieter.
alexjhon castellanos: I just used I'm waiting let's see if work
shyflirt1: The code did not go away as the cat converter and O2 sensors had already
been damaged. If I had acted sooner, it might have saved them. The car did
run better and quieter afterwards. I have since replaced the catalytic
converter and O2 sensors, and the code went away. Something to try are some
fuel additives that will supposedly clean the cat converter like Cataclean.
I don't know if they work though.
Jeff Eatmon: it's not going to work, i tried it and cured it for 36 hours. when i drove
it after that the stuff turned to dried clay, the crack came back and i
poked it with a screwdriver and it just crumbled off. going to try to get
it welded now.
Joey Davis: Works great thanks did High temp JB WELD lasted a couple weeks.
machia0705: Will this work on a half inch hole on an exhaust manifold?
GhostxofxHelena: This stuff sounds amazing! Though I passed inspection/ emissions, I have
suspected my manifold has been cracked for a while (replaced O2 sensor
after check engine light on, reduced power when I accelorate, and recently
smelling gas exhaust when breaking coming from my vents- NOT good). I don't
know the condition that it's in and I can't afford a replacement manifold
now-but this is a good temporary fix until I can afford a new one? I know
almost NOTHING about cars, so thanks for the suggestion!
rufkl: Looks as if you maybe got a little on your o2 sensor.
machia0705: I have a 1/2 inch hole in my exhaust manifold on my Ford expedition V8 and
is easy to see but very hard to get at to repair, any suggestions? Is
brazing the only fix? Can this thermo-sealant epoxy really work?
shyflirt1: I had it on there for a few months until i was able to replace the
shyflirt1: I don't know if this stuff will work on a gas tank. In the instructions
they mention that when machining it, not to use oil. That makes me think
that petroleum products might damage it.
riki Ramirez: Uthat will work fir a wile but eventually it will dry and cack off its
better to wrld it
retrofaboo: how long did you use it for?
Jake Saratoga: No it wouldn work. A factory exhaust system has quite a bit of back
pressure and it would blow the hole back out. Best bet is to get another
manifold from a junkyard or get it brazed.
shyflirt1: 10 minutes? It takes like 24 hours to cure in warm weather. I had a halogen
light on it to keep it warm and let it sit for over a day.
Simba Lage: great video going to try this same stuff on my gas tank. I know heat helps
this stuff get stronger but at the top it should work will post results
shyflirt1: I had a 250 watt halogen work light shining on the exhaust manifold for the
duration to keep it nice and warm.
Bryan Theobald: well yea, ten min to extreme heat and then let it sit for a day. I might
try again with another tube but dremel it more, i didnt take too much of
the rust off and im going to let it sit for a full 24
Dave Wood: did you have a p0420 code for catalyst efficiency? if so did it go away
after sealing the crack, i have the same issue with the 420 code and have
been told by multiple sources that the crack is not the problem, but im
still not totally convinced that repairing it wouldnt fix the code.
Takuan66: why don't you weld it???
Cole Cormier: @Jake Saratoga
Cole Cormier: freak you Jake! I bet you a greasy mechanic trying to rip people off when
this stuff works great. It will flake off if you either don't mic it
properly or don't clean the surface properly before application. Kiss my
uggabug: this stuff is like Dencorub for for Cars... makes you think it's doing
something but it actually doesn't do anything.. the carck will continue to
get worse and you'll keep having a problem that will just keep getting
bigger when you could have fixed it properly when it was small.
Bryan Theobald: How did you cure it? I had a heatgun on mine for about 10 minutes and i
caked it on as well. however mine just puffed up and came right offf =[
Jake Saratoga: Welding it requires it to be removed.
Jake Saratoga: Thats stuff will work fine but he should have drilled a small hole in each
end of the crack to prevent it from getting bigger. If you could get a
torch in there brazing would be best
Shane Rhabb: Did it cure just fine in any temperature? The instructions say that it must
cure for 24 hours in 80 to 100 degree ambient temperature.
