101 Exhaust manifolds.

Morph is still in bits and the heads are at the local machine shop for
reworking... stud holes for manifolds and valves replaced and ground is as
required with new valve guides too.

Anyway, while Morph ois stripped down I was pondering the issue of the poor
quality exhaust manifolds.

If my recollection is correct it's the Left hand manifold which cracks.

At the risk of sounding thicker than custard.... which is the left hand
manifold. I have two depending on where I stand looking at the engine

Also if I was to remove said manifold would it be worth getting it machined
to ensure flushness of each of the ports or would this really be puching
oned luck and destined to fracture it in the process.

I'm looking at prevention of future problems here.

I've got a full set of gaskets which I believe will assit partly in the
existing potential problems being avoided. Do I just fit these and keep
everything crossed?

Left-hand and right-hand are always from the point of view someone sitting
in the drivers seat looking forward as far as LR are concerned.

Just don't apply the same rule of the road. Unless you're in forn parts, of
course.

Re: 101 Exhaust manifolds.

The problem with the manifolds is they they are machined too soon after
casting. Apparantly cast iron should be left for 6 months or so before
machining. If you were to carefully measure you will find the port
faces will be slightly out of true. We looked at re-machining them but
due to the shape of the manifolds it's very difficult to set up. Use
manifold gaskets as suggested above and don't over tighten.

Skimming 'em would be a 30 second job, CLAMPING them to skim them would
take hours....

Or thermally cycled up to red heat and back a few times - it relieves
the casting stresses in the iron.

Thinking about it, If I were to do one, I'd probably cast it onto a
fixture with low melting point alloy, then skim, reheat in an oven and
release the parts.....Its do-able that way, and you don't fart about
trying to level everything properly. The LMP does it for you.

no, I drive on the left, therefore oncoming vehicles (should have been an
"oncoming" in the first bit, I admit) are on my right, i.e. to starboard.

Find a sod-off surface plate and set to with some grinding paste?

I once did an alloy head like that.
