101 Exhaust manifolds.

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.

Yeah, and the right one... :-(

Cars are like boats, Port (Left) is the bit on your left as you drive / sail it - Not as you're looking at it standing at the front looking in. I found this out once, to my cost, after removing the wrong head.

Use the gaskets :-)

I did think about machining them miself, but TBH, it's prolly not worth the hassle.

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

(nautical rule of the road is "pass other vessels to port")

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....

So you drive on the right Austin? Thought itwas a bit hairy in WAles!

Yeah, my thoughts too. Best let sleeping dogs lie I reckon. Thanks folks!

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

If you were to carefully measure you will find the port

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.

Go and find an engine rebuilder who has a manifold grinding machine (no clamping required) - he shouldn't charge a lot to surface one unless it's very badly warped.

Austin Shackles uttered summat worrerz funny about:

Done it on a water gallery on the VM engine... that took forever using 800 grit (massive roll I was given).

Did the lob though. I think my arms may drop off first doing it on cast.

That's what I thought, but your description implied road and water were the same, but here you suggest otherwise. Of course, Paddy was going to holiday in America and he practiced before going and decided it was blooming dangerous!

Is this like a bloody big linisher ?

Steve

Effectively, although they generally have a rotating stone set into a flat tabletop.

Not seen one of those. Is the manifold offered up by hand then ?

Steve

It is - but it takes about 5 minutes to make a suitable bracket to bolt to the outlet studs to hold it at an appropriate angle if you're really worried about not being able to hold it true.
