Exhaust leak found at down pipe gasket is it hard – cb7tuner forums o goshi

You’ll have to remove the splash shield (see your other thread on this topic). If you have an OEM manifold, there are three studs in the exhaust manifold and three 14 mm nuts you can access from below with a long extension. Take a look and see how rusty the nuts and stud threads are. If you have time, blast them with penetrating oil when cool and leave them for a while. If you have the proper thread die, you could try to chase the threads as close to the nuts as you can. If you’re lucky, the nuts will come off. Worst case scenarios include the nut seizing on a stud, a stud breaking (PN 90065-PC1-300), or a stud unthreading from the manifold. If they’ve been on there a while, you might also be ready with new nuts (PN 90212-SA5-003).

If you strip or break a stud and part of it is still exposed, there are special sockets that can be used to remove them, then a new stud can be installed. If the stud breaks without leaving part of it exposed, you’ll have to remove the manifold to deal with it.

Thank you. Most of the nuts and bolts on car have been ok to get off so am hoping this is too but this is hot exhaust so got fingers crossed. I don’t think it has been off in at least 15 years. Good to know i must take off splash shield. Now i might do my radius rod bushings also. And again thanks for the tips.
