The cracks (there are two) could be characterized as "hair line", but they are long. I have an extra exhaust manifold but I was just wondering if anyone had tried this stuff and whether or not it works. It would certainly be a lot easier since I think I will need to remove the intake manifold at the same time and, of course, there is a coolant connection between the two manifolds. Then there is the issue to finding the gaskets and the potential of breaking something else while doing the job-which almost always happens. The time and expense to try the Permatex solution would be negligible but on the other hand I dont want to waste my time either. Im just asking to see if anyone else had any experience they wouldnt mind sharing.
