The exhaust manifold on ffragle needs the 3 down pipe studs
drilling and retaping. Does anyone know what thread they are? So
I can get a tap set to suit. :smilewide:

Usually 5/16" UNF, but I would get someone to check!

Ditto and studs are available from usual suspects.

I would suspect that, the manifold being cast iron, you may find
the studs are double-ended. The bit screwing into the manifold
being 5/16" UNC and the bit taking the securing nut 5/16" UNF.
Get the replacement studs first, before you spend money on a set
of taps.

mine are same ended, one thread area longer than the other.
If you can 100% make sure that proper L R parts are in fact
'proper' , get genuine studs. Aftermarket ones are shite and
will rust into the manifold in aboot 24hrs.
fecking things. :smiley-furious:

i was actually refering to the other end, in the manifold. God
knows how old the ones I took out 5 yrs ago were, but they came
out piece of piss. Not so the current ones.
...but I know what you mean Lurch, fit brass nuts and hopefully
you'll never need to take the studs out again and they can rust
the fuck up as much as they like in the manifold.
....in theory ;D

I've got 2 manifolds for ffragle,but both have snapped studs in
them :2mo5pow:
I did look at buying a new one but at nearly £50, I thought that
buying a tap set would come in cheaper and if need be it's there
for future use.

Don't buy a cheap tap set. The cheap ones are made of chocolate.
For years I thought there was some black art to cutting or
re-cutting threads, as I could never get them to cut right. Then
I used a decent quality tap set and it suddenly became quite
easy.
I do wonder if the same is true of brake line flaring kits,
because I can never get a decent flare from my el-cheapo brake
flaring kit.
Cheers

.....speshul cutting and tapping lube helps more than you can
imagine and to that end, putting some light oil onto the dies
of a cheapo flaring tool helps too........ but best not to buy a
cheapo flaring tool in the first place.
