Is that JB weld on the baffle plate?

good diagnostic process, another use for the shop vac! Penetrant and heat are your friends for this.So, I sprayed soapy water all over my exhaust manifolds to try an isolate a leak. Then I placed my shop vac hose into the tailpipe and the soapy water started to bubble around the exhaust to block interface at cylinders 3 and 4. I have been hearing the telltale signs for a while. But after the car warms up, the "tick-tick-tick" sound is almost imperceptible. (well, except to me) So, now that I have identified the weak gaskets, I am terrified that as I begin to remove studs/bolts things will break off and I will be in an even worse situation.
Planing, yes, great idea. I just bought some "Kroil" penetrant. Trying to really get into those threads. I have read applying whatever spray, then starting the car, letting it warm up to draw in the penetrant. Let cool, and repeat, may help get the lube in there.Soak in penetrant for a couple days. Heat the nuts with a blow torch a couple times during that time and reapply the penetrant. When ready to go for it heat them up again and loosen them. I’d then take both manifolds to a machine shop for planing to make sure they are true and lie flat against the head. They can remove the old studs, clean the ends, and install new ones so they don’t break in the future.
Kroil is the best I have used. Two tips on things I do when seeking to remove bolts that have been on a very long time. First, after your first round of Kroil, go around each nut with a pick, and try to dislodge any corrosion right at the point where the nut meets the manifold. Then repeat the Kroil treatment. Second, when you actually put a wrench on the nuts, start by slightly tightening them just enough to get them to move. Once you get them moving, they often will spin right off.Planing, yes, great idea. I just bought some "Kroil" penetrant. Trying to really get into those threads.
