bugger.
my xr4x4 had the gaskets missing on one of the exhaust manifolds. tried remove the manifolds and managed to shear one of the studs off,
can't drill it out in situe. so it's either leave it sounding like a tractor (not much worse than it has been without the gaskets!!), remove the head and drill the stud out or leave it and get a shift onwith the 24v cossie conversion.

the only problem is I have no spare time and i'm skint.
