Finished the Oil Trap setup & got it all plumbed in
No more oil vapor in my Engine bay OR intake System
Can't see it but its packed in with steel wool I didn't forget that part
Looks ok in engine paint black

Looks good. All the best with the manifold(s)

I'm about to throw these manifolds in the Bin
somehow my spare manifold ( ie the one i have received back from welding and planing ) seems to have a different casting that would not allow me to get a socket in there to tighten up the exhaust nuts.
As i had my heads fitted with m10 studs and 14mm nuts this made things extremely difficult
so off the manifold came and a combination of grinding down a socket and "clearance" the manifold around the studs seemed to get me back into business.
Only to find that i put my glasses back on and the manifold i just got back from welding had a crack in a totally different place to the one that was just welded which was hidden underneath a layer of a the Iron Oxide.
I'm spewing at the moment Rakaia Cruise isn't looking good for now

can you not just weld it yourself? i know its not ideal to weld cast iron, but if you dont have access to a mig, either take it to uniweld, speak to grant and tell him i sent you, or i can have a crack at it. it wont be pretty, but it might do

Getting it welded is not the problem
the problem lies in that the casting between a 1984 manifold and a 1985 manifold is diffierent
which means that with 10mm exhaust studs ( factory was 8mm ) clearance for the nut is already tight enough i had to grind the shit out of a socket ( no access with an open end spanner )
the crack is right in the groove where the socket has to slide in to.
which means that any welding ( strong enough to do anything ) in that area will mean i have a manifold that i can't bolt to my cylinder head.
I guess i could slap it on the side and run it until my WOF runs out ( 1st may ) and then finish these
The shorty headers are the easy bit, getting from each header to the turbo & where to put the turbo and wastegate is the difficult bit which is exatly why i havn't got that far.

Don't join them up, just put a turbo on each side
