I’ve had very good experiences with Pierce Manifolds for my Weber parts. Like you, I’ve found the Redline website unusable.

Redline now states that they do not sell to the public, go to distribution.
So why do they still have a website?

Today was special!
I finally began putting parts back on the engine.  :)
As part of that effort I modified the cylinder hold downs I bough shortly after finding the engine was going to need a rebuild.
I had to cut curves into them to clear my pistons.
I also made up some spacers to take the place of the rocker stands.
They are needed to use the original head bolts with the hold downs.
My oversize pistons will be installed from the top since the rods will pass through the bores.
I did take Salve Sacco's advice and fit the brass oil restrictors under the cam.
This should increase my oil pressure just a bit, which may be offset by the hollow billet cam with oiling at the lobes?
Looks like I will have one more small order from France and just one more tricky mod to do.
Final trick is that I intend to send my timing chain and sprockets out for Cryo treat.
This is claimed to virtually eliminate chain stretch and is not expensive.
Not much point in my fancy adjustable cam gear if the chain is going to stretch and alter the timing.  ;)

Nicely done.

Oil restrictors reminds me of a my buddy who raced a Shelby Mustang with a 351 Cleveland engine. He needed oil restrictors for the cam circuit so there would be adequate oil pressure and volume at the mains and rods...

Small order placed with the Renault 16 shop tonight.
Only source I could find for a new lower timing chain gear.
Once it arrives I intend to send the set out for Cryo treat.
30,000 miles seems like short chain life to me.

Anyone have a source for the illustrations from the "PR Book" that Renault16 shop uses on their site?
I managed to copy some of them to my photos file and then circle the parts I was having trouble ordering.
This would be easier with more legible pics and text.

30,000 miles for a timing chain! Are you sure? A belt lasts longer than that!

Timing chain to be checked and possibly replaced at 30,000 miles.
That is what I read, this site or one of the manuals, not sure.
I agree that is very short life.
The sport bike guys stretch chains quickly, they are long and do insane RPM.
Cryo is making a real difference for them so should be even better for our cars.

30k miles seems low to me.  It’s not a long chain and I have seen them with way more miles than that.

Racing?  High rpms?  That’s another matter.  You’d be pulling it down for guides and rings a lot sooner than that.  Probably change the chain at the same time as well but it wouldn’t be why you’re pulling it down.

Hmm, my post of a few minutes ago disappeared.
Haynes R16 manual, page 36, item 36.
"It is a sensible precaution to renew the chain at about 30,000 miles (48,000 km) and at a lesser mileage if the engine is stripped down for a major overhaul".

I don't see the need myself.  Certainly not in the Lotus or Renault manuals.  Keep up with the oil changes and you'll be fine.

The good news is that the weather was so nice I worked on my Lotus body today.
The bad news is that I dug out old Bondo® and found out just what a botch job some "Bodyman" (8 years old?) did on my left front fender.
Now I have to decide how I want to repair it properly.
Choices seem to be cut the fender off my other body and graft it on, or make a splash mold for a new part.
Either is a lot of work.
I kind of hate to destroy the spare body, plan has been to keep it around in case I seriously crack this one up, get rear ended, etc.
Anyone have an S2 left front section they do not need?

  Can you lay a piece of plastic or wax paper on the spare body area and lay some glass to duplicate the fender?  a picture would help.  I think you'll be much happier that you tackled the repair sooner rather than years later.
