J*B Weld Cure Time ?

[SkylineDream9]

So I made a steel plate to block of the EGR tube on my Pace Setters and J*B welded that sucka on there and was just wondering how long I should wait until I can drive the beast again. I welded it about 7:30 this morning, it sat in the blistering heat (90 farenheit) all day. In the meantime, I cleaned out the whole car, washed, and detailed it. Looks sick, I just want to drive it now !!!

i think it says 16 or so hours cure time.

Re: J*B Weld Cure Time ?

you should have taken it to a welder and had that plate welded on. Im not sure if that jb weld will handle the job. the pipes are always expanding and contracting with the heat.

jb weld will be fine

you can use it for cracks in your engine block

I'm with you on this. Even though they CLAIM it can be used to seal a block, welding it correctly will always hold up. I'd use the JB weld elsewhere and not directly on any engine parts. JMO

Oh, and read the instructions for the cure time and try to follow them the best you can. I know it sucks to wait, but it's better than doing a job twice when it could have been done correctly the first time.

i have JBweld on an intake manifold on my camaro, and it has been fine

Re: J*B Weld Cure Time ?

headers are hot guys thats the problem, they are the hottest part on the entire car.


doubt it will work...


I had a broken bolt on my EGR vavle on my 3.4L used to set of codes occasionally, so I jbwelded the EGR on, let it cure for 30 hours. Started the car up, let it idle looking for leaks, once the car hit normal operating temps, some of it rolled off like water.


So it lasted about 10 mins in my drivewya without driving it.

no offense, but whats your point?
the intake manifold only gets to like 150F? I'm not 100% sure though.
While the exhaust manifolds/EGR/exhaust valves/CCs get ALOT hotter


What would be better? JB Weld or Epoxy?

Re: J*B Weld Cure Time ?

I've got JBweld on my EGR and it has held for around 5,000 miles now.
