It has always run rich and the right combination of timing and carb tuning has been elusive. I may have damaged the power valve as I did have backfires through the carb at one point. I have a replacement to fit and see if it helps. I've also read that the idle feeds can be reduced with a kit...
It turns out my problem was not anything to do with the operation of the safety switch in the transmission. It was working fine and only grounded in neutral as intended.
In my case, it was that a previous owner had replaced the starter relay with a non-standard one and mis-wired it so that the...
Thanks but no. I've never used anything like that. Coolant now looks clear.
I think I may risk taking car for a run then recheck coolant and oil for signs of contaminations.

Plugs out and compression tested.
I think (at least I hope) I cried wolf. If so, my apologies but gratitude for all the advice and support.
Compression test results
Left bank : 1 - 130, 3 - 120, 5 - 120, 7 - 115
Right bank : 2 - 130, 4 - 120, 6 - 130, 8 - 120
So, no milky, yoghurty...
1. I took off the expansion tank. It had practically nothing in it but there were blobs of oil.
2. I put a funnel down the radiator and added fluid through it to raise the level and make it overflow. I captured the overflow in a jug. the funnel picked up some sludge on its sides as it...
Thanks. i'll get one.
The more I think about it, the more I find this odd. Yes, I read of oil contaminating the coolant but I'd never heard of it until today. I can't think how else any oli got in there but maybe it's just a thin layer that contaminated the coolant during service or...
I am a total newbie at this issue but I have found refs on internet today to the higher pressure of oil system sometimes forcing oil into the coolant.
If it's not that, how else can oil have got in there?
I haven't seen white smoke yet that happened on my last car that blew its head gasket...
Thank you. I just ran out to stir the coolant as you suggested. No milkshake. It just looks like a layer of oily stuff and no sign of coolant in the oil checking dipstick and looking at valves through oil fillers.
So what do I do now to prevent damage until I can get the heads off? Drain...
No oil or transmission cooler inside the radiator on mine. There is a separate transmission cooler. Rust? I'll look again but it seems unlikely. Coolant was all clean looking last weekend.

I only got this car back on the road a month or two ago after rebuilding the front end. I went to top up the coolant this morning and it looked a bit dark. See the pic.
On the lower right, the large area is fresh coolant. The blobs on the left are coolant from the radiator filler.
Pretty...
