DankWilliamsJr: Thanks for the video. I think I'll be going with the ThermoSteel until I can do a full replacement. For some reason, someone at Chevy thought it would be a good idea to make the manifold and cat converter one solid piece, so now I get to pay $200 extra for a chunk of platinum I probably don't need.
aguilayserpiente: Did the seal hold up after driving and all the expanding and contracting of the manifold?
easleybadboy: You should get better mileage due to computer not dumping more fuel into the system as a result of your O2 sensor telling it that the AF ratio leaner than it really is because its picking up oxygen getting sucked into the crack. FIxing to do this repair tomorrow. Was going to just replace with a header but have put it off long enough and dont have the funds right now. Hoping the thermo steel will hold up a few months till I can install header. I could weld it but I hate taking parts off twice in short order and I am getting header regardless.
How well has the quick steel held up for you.
Billy Denham: They should have called it Liquid Crack Repair!
super mario: I patched my hairline cracked on my exhaust using jb weld original cold weld. dried it for 2 days, after two hours driving my vehicle it cracked and fell apart, it's not very effective on exhaust manifolds. how is your quick steel thermosteel doing, is it still glued and intact?
Bobby: Hey @Rj The Bike Guy, I have a crack on the "connecting" point of the Resonance Chamber and the Connecting pipe. It's a fairly old car but the muffler is in great shape aside from this crack that was caused from excessive vibes that have been since fixed. My question to you is: Do you think this stuff has the ability to bond strong enough to keep small vibrations from causing this are to suffer cracking again or should I try to get this area welded by a professional?
captain deadpool: I am getting a error for that o2 sensor and I noticed the same crack can that cause the sensor to test bad or is the sensor just bad?
Paul Griffin: We used this stuff and it lasted for about 2 weeks and popped back open... Only real way to repair a cracked manifold is to replace it.
Pat Thompson: Well I did all that cleaning and used the quick steel stuff and after 100 miles it all broke off. So what up wit that?
pked9: QuikSteel/ThermoSteel ... 200F max , i dont care what they claim!!! test it your self.
Clorox Bleach: My D16Y7 manifold broke, holy crap i want to try this to pass emissions
AlphaLady777: I attempted to use Quik Steel Extreme to build-up my worn-down exhaust pipe. I mixed it for a long time, applied it with a screwdriver, refixed it when it dripped the wrong way. Let it cure for 30 hours before filing it to fit my exhaust-donut gaskets. I thought, "This is going to work!" Then, it rained last night and the Quik Steel "melted" in the rain. WTH?? All that work -- gone! I am furious............
vtf500: cracks can be loud.
SernieBander s: I have a crack in the same spot on my 98 civic lx I may try to do this cause my car is filling up with exhaust it's bad
James Brown: simply will not work
john crane: what he doesn't show you in video is to drill a 1/8 inch hole at each end of the crack to keep crack from get bigger after patched. then also grid the crack 1/8 of an inch then put epoxy on. let cure 24 hours then also heat cure the patch after. read direction not what this guy did.
Aurelio Rosales: for some people it works, for others it doesnt. it's worth a try befor buying a new manifold or whatever you are trying to fix.
jeffscomp: Was the car real loud with that crack in your manifold? I am getting exhaust fumes thru my heater vents when at a stop but my exhaust is still pretty quiet. I'm not sure what the problem could be and it is getting me sick.
Misster R: The stuff fails after a few days...regardless of how you prep it. I have patched mine a dozen times now..nothing out there is a permanent hole fix on an exhaust manifold out of a frikken jar. I tried em all...and while this product blew everything else away...IT FAILS!
