Exhaust Manifold studs?

Eliseparts don't stock them - any ideas where to get any?

Typically the nuts are welded on to the ones I took out. Alternatively I could get some threaded rod, but should it be high tensile?

Cheers,
Iain

They are a Rover part, find a rover stockist

Or even Landrover thinking about it

Thought as much, just wondered if there were any alternatives as we don't have a Rover stockist anymore...

Grub screws ? or Cap screws ? not being an expert would these do ? what is the thread ?

I'd get some threaded rod and locktite it into the manifold. I did all the inlet and exhaust manifold studs on one of my scirocco's with stainless threaded rod. Makes it much easier to undo next time round

A quid each from any manufacturer that uses the K, e.g. Land Rover dealer.

Threaded rod will work, but whether or not you'll ever get it out is another matter.

Torque on the nut is only ITRO 45Nm; the head won't take more than that; that may not be enough to make S/S stretch and lock in the threads.

Thanks guys,

Fridays job is reconnecting all the pipes I disconnected when taking the old K out...

Saturdays job is bandaging my skinned knuckles

and Sunday's job is firing her up

Good Lad.

For me, Saturday = getting alternator out, plus making sure I don't have melted light connectors. Then Hatton/Mayweather avec beers

Sunday later, Elaine's orchestra christmas concert (should be good after watching the pugilism at f**k-knows o'clock)

Are ye sure cap'n... will she take the load?

The manual says nada about the exh manifold studs so I have yet to torque them up - as one of the last things to do, I don't want to ruin all my hard work by stripping the head threads

Well, in general M10 threads into alloy get 45Nm, hence I assumed it would be the same. In reality nobody uses a torque wrench to do them up anyway, so quite tight with a normal 1/2" ratchet is probably tight enough

The K-nuts will lock onto the studs anyway and so you won't lose them; you'll hear it blowing (sounds like an old beetle) and you can just nip them up a bit if they do. So you're better off erring on the side of too loose rather than too tight.

OK - I was quite surprised at some of the engine mounts bolts - the RHS mount to engine bolts are 145Nm

The exh studs aren't M10 though, more like M6

A good nip up with the ratchet will do then
