Thanks mate, obviously with the head off it makes sense to do a refurb on it. is there any detailed info in the technical manual re the head removal?

I’ve been through exactly the same thing 2 years ago (mine was cylinder 4 with coolant). I have a long post about this although there are numerous posts about head rebuild.

Afternoon Gents, went back tot he car this PM with a multi meter. The leads have got radio resistance stamped on them. The one from the coil to the distributor cap gave a reading of 19.85. The leads from the distributor to the plugs gave no reading at all?
Trying to do some research on plug leads and resistance but what do the figures above mean?
Thanks again.
Paul.

Wow! That's a lot of resistance. You should have zero resistance on your coil wire for best results. Spark plug wires should have 1K ohms  and use NGK   BP5ES spark plugs.

Hello all and many thanks for the responses.

Well in the end the car went to a specialist which given some issues that popped up, was the right thing to do.

When the bonnet was removed, the captive nuts inside the bonnet on the nears ide dropped from their cages which resulted in the bottom internal corner of the bonnet frame being cut off. The cages were then rebuilt and the nuts re-inserted before the bonnet was welded back together and painted internally. They did a very nice job.

The head was completely refurbished once off, the thermostat was replaced and a 123 Ignition distributor fitted. This is a Bluetooth item which allows for adjustment from the App, but more interestingly allows it to be switched off from my phone.
Anyway the car is running really well now and it's good to have it back given the current UK weather. I must put some photos up.

Auto box next so more questions for the experts.
Thanks again.
