What does an exhaust manifold leak sound like?

What does an exhaust manifold leak sound like?

A leaking exhaust manifold will almost always create a ticking or tapping noise. Often, the sound is more pronounced upon startup when the engine and the manifold are both cold. The noise may diminish or disappear once the engine warms up and the manifold expands, closing off the leak.

Does J-B Weld stand up to heat?

How much heat can J-B Weld withstand? Original J-B Weld can withstand a constant temperature of 500º F. The maximum temperature threshold is approximately 600º F for a short term (10 minutes). However, in areas where the continuous temperature is less than 450º F, we do recommend our HighHeat epoxy putty stick.
