Similarly one may ask, can JB Weld be used on intake manifold?They work just fine. Its really not rocket science to mix jb weld. So jb weld is some strong epoxy and will hold up for a long time depending on how and what you use it for.One may also ask, will cracked exhaust manifold damage engine? This can damage plastic components in the engine bay. There’s also the possibility that it will affect engine performance. If your exhaust manifold is cracked or leaking, the back pressure in the exhaust system will be incorrect, which can reduce engine power, cause sputtering and other problems. Correspondingly, how much does it cost to repair a cracked exhaust manifold? Your exhaust manifold repair will cost you between $570 and $900, with labor taking up $400-$550 of that, and parts running between $130 and $340.Should I use exhaust manifold sealant?You shouldn’t need to use sealant on the gaskets. Most exhaust manifold gaskets either come with their own sealant (like Fel-Pro’s do with the silver looking stuff), or they are metal and don’t require it either.
