Hi ya Mitch

I went with a MGB chromed air Intake for the amazon it fits nice and snug looks amazing I will be using that modification again on any custom builds looks the part everyone comments on that when they see the custom amazon estate in the workshop.

Kind regards

Russ, I've bought a 0.8mm head gasket thanks. I've been recommended a rolling road at Copthorne near Gatwick. My mate takes his mk1 cortina track car there.

That may be better as cortinas often run side drafts so aware of jetting.
You want and try and get two runs in during an hours session with a period to make adjustments change jets. It's useful that people have the understanding to interpret the dyno /analyser and know what changes are required.
The other issue I have is Solex ADDHE are not a common carb and jets even less so. I have some but Sod's law means they won't be the ones I need. Yes you can solder them and drill them out but it's a palarva.
How much do they charge and do they know the 123 ignition system?

How could I have missed it. The front cam bearing is horrible. The other two are fine which is good as I can imagine the centre one is a proper pain. So removed the old one easily with a socket as a drift. Fitting the new one without damaging it could be more of a problem. Thinking of turning down a piece of wood. Any better suggestions please? Oh and merry Christmas to all. Julian

With the front cam bearing being that bad you are rather trusting when saying the other two are OK. No they aren't easy and probably best left to an engineering shop who knows what they are doing. The rear plug (like a freeze plug) will have to be tapped out from the front.
Hardwood or nylon rod for a drift for the front one.

You were right Derek. A dental mirror revealed that though not worn like the front bearing, it would be folly to leave them unchanged. I removed the front one easily and have spent a couple of days pondering whether to do the job myself but the chances of distorting those thin walls with home made tools seems highly likely. Back to the machinist we go then.

Julian, I'm watching this tread with great interest because I'm about to overhaul my B18.

As you've taken it apart have you found any significant problems other than worn cam bearings?

Nothing unexpected Mike. When I put the block in the parts washer, the amount of crap that came out of the water jacket was phenomenal and again once dry, I blasted through with an airline and still got more out. This is clearly worthwhile to avoid overheating later. The cam bearings are now in as is the cam itself and the crank and timing gears. One piston/con rod assembly in last night and I'm about to do another. Inclined to take things very steadily. Will keep you posted.
