Hi all, me again
I guess you guys already know this, but i'll mention it anyway/.

Machining needs the gasket in place.

Hi all,
Details of the actual machining are above my pay grade.
I had my seal machining done by Anthony Pearson, here in Adelaide through SA MG club. He also sells various LED for vintage cars,
Seal was a Mazda part.
PDF attached is stitch together of screen shots gives dimensions of seal.

There's a bit of misunderstanding here with rocker gear spacers etc.
'Usually'---the bigger the valve lift, the 'lower' the rocker gear needs to be.
For proper operation/geometry there should be (at right angles to the valve stem ) At 50% valve lift of the cam being used,---- a straight line from the top of the stem, through the centre of the rocker shaft and through the centre of the bal...

The cutter can be positioned for different OD seals.

Just adjust cutter (held in position by a grub screw) until both sump and timing cover are both being cut, so a circular out face is the result.

Recommended seal is high speed Viton seal 7mm wide and with the XPAW engine we used a 49mm OD seal, but normally a 47mm OD seal will be sufficient.

It used to be a common mod on the 12G295, back in the day, to braze up the oilway and re-route it up the stud hole through the head. I had a head like that on my A35. It went like stink, but the deck was a bit thin ;o)

It is not possible on a 12G295 to shave off the amount equivalent to the thickness of the spacers because of the proximity of an oil gallery to the head surface. The spacers are to make the rocker arm sit square on top of the valve. The cam is a new billet Kent 266, not reprofiled.

Thanks Guys, I managed to find one in New Zealand, so didn't need Ed's kind offer.

It’s not just machining the head that changes the geometry. The camshaft can also have an effect, particularly if it is reprofiled and with higher lift.

A friend has an earlyish Mercedes SLk. On paper it appears to be an ideal car. They are not expensive, stylish, well kitted out and not too much electronics. However because of emissions the road tax is £700!

Brewer’s Fayre is another one of the group, that are also meant to be closing.

I can’t see the ones that are attached to Premier Inns closing down. Maybe they are the ones staying open, but under another name.
