I'm thinking that the plenum might not be airtight?

The design needs a little "finessing" I must admit, but I think it could well catch on. The customizing opportunities are virtually infinite. Just working on the copyright now.
Should be relatively cheap to manufacture so therefore an extremely high profit margin. laugh

This weekend's jobs were:
Replace Clutch Master Cylinder - old one weeping along the actuator rod back to the clutch pedal.

Replace the engine bay heatshields

GRP repair to Left Hand outboard seat belt mount area of the body - I had to "encourage" the body past the bolt (which had sheared) during the body lift.

So, On Friday I replaced the clutch master cylinder and removed the old heatshields.



Yesterday I made up a new right hand heatshield - I am waiting for some more heatshield material to be delivered next Friday, so that I can do the left hand side.



As a bonus job I also wrapped the right hand exhaust manifold.



Don't worry, the tie-wraps will be replaced before refitting the manifold.

Today I fitted the new right hand heatshield.



That just leaves the GRP repair for tomorrow.

Next Friday's jobs are: Make up and fit a new left hand heatshield, wrap the left hand exhaust manifold. smile

Great thread as I am rebuilding my 450 after an "excursion". I too had the engine out and thought 55k miles better have a look at the cam, had 2 lobes really badly worn yet the engine was as strong as an ox, whipped the cam out and noticed issues with the bearings so replace bearings, crank out and new mains/big ends at the same time as per you all courtesy of V8D helpful guys
Good luck with you rebuild

Where did you get the heat shield and how easy was it to cut, shape and edge.

I got it from APT in Lenwade, Norfolk. 01603 870990.
I used the old heatshield as a template, including marking for the rivet holes, then cut it to size with ordinary scissors - allowing for a hem the same as the original - then glued the hem first to make it easier for stitching by hand. To get a neat finish to the stitching I marked out the position for each stitch to match the original stitch length and distance from the edge of the material. I used a thin needle and the strongest thread I had to hand at the time. thumbup
Original stitching:

New stitching:


I am using relatively thin heatshielding material as I am also wrapping the exhaust manifolds. smile

How will that cotton stiching stand up to the heat of the manifolds? Is that what they used originally?

I don't know what they used originally but I could snap it by hand. It will probably stand up just as well as the original stitching. smile

The stitching is purely cosmetic anyway since I glued the hem first and with wrapped exhaust manifolds it should see significantly less heat then the originals anyway. thumbup

Thanks mate. I did the GRP repair today, so that just leaves the left hand heatshield and wrapping the left hand exhaust manifold.

Should have the chassis back soon as well! biggrin

What paint did you use to paint your cleaned parts ?
I tried spray hammerite but found it so thin that it almost runs straight off.

Same here mate, the only way I could get a decent finish with it was lots of very thin coats, with about 20 mins flash off between coats and no more than 4 coats without leaving it for a week if it still required more attention.
So, after doing the rear ARB brackets, for the other white parts I used brush on smoothrite - much quicker and easier - especially if the paint and the part are warmed up before applying the paint.

I take it you've finally got round to doing something on Kate then? biggrin

Fitted the LH heatshield and wrapped the LH exhaust manifold today.

So, that's all the jobs done.
Just waiting for the chassis to come back and this will be delivered next Friday - 15th May. biggrin
