Lockdown has lead to me catching some daytime TV and I have been watching the occasinal Wheeler Dealer programmes. There were a couple of things I had not seen before:
1, There was a Jag where he did a chemical De Coke of the engine. Involved plugging in a unit that burnt some chemicals in the engine and burn out all of the carbon build up. Before and after tailpipe emmisions were seriously improved.
2, Today on a TR6. Replacing the normal water based coolant with some special coolant that did not presurise the system.
Anyone got any experience of either of those?
