All good then Stevie :wink:The studs etc that I bought are these ones of eBay:
Appear to have a locking washer......
Okay, so just been out to have a tinker with this exhaust manifold - made sure I had the correct combination of socket/extension/torque wrench to retighten before undoing anything....I can access all nuts (just about) with various combinations, however there seems to be a BIG stumbling block in backing the manifold off the block. If you look at the picture below, you’ll see what I mean....the down pipe has about a maximum of 1” to move back before the pipe itself hits part of the frame.....I don’t think 1” is enough even to back it up off the studs, let alone clean up both mating surfaces and replace studs/reassemble......There is enough room to slide the exhaust manifold back off the studs for gasket replacement without dismantling the rest of the system.
I seem to remember that I gave mine some support from underneath with a small jack at that time so as to not stress anything in the system. I am going back 6-7 years ago though, so the memories are a little faded...
The system should also hinge down a little as well, which should give you the room to remove and/or replace your studs.
Same here Stevie.I have no suggestions but I can tell you that on my 1995 F, I can move the exhaust manifold back sufficiently to allow me to get the manifold off of the exhaust studs and remove the exhaust studs from the cylinder head.
Up, you say? - here’s me thinking that it should drop down and back??. Should I be trying to back the manifold off the studs and then lift it up above the studs?They are somewhat different. But what I think you will find is that when you unbolt the exhaust manifold, that 1" between the exhaust pipe and the subframe will magnify itself into at least a couple inches of movement up where the studs are.
That’s a very good idea, Austin. I think some of the studs will come out with the nut seized on anyway. The only thing I’m really concerned about is getting access to clean both mating surfaces for the new gasket....pretty difficult to see the head as it is, let alone with the manifold somewhat in the wayWorth removing the old studs by the two- nut method, before removing the old gasket? Replace with new gasket and wind in the new studs by the same method, before tightening the manifold using the new nuts.
