Hi all, I have a 1970 HT with a 186 and i want to have it running unleaded fuel. Adding lubricant is not an option. I'd like it done properly. What steps do i need to take to get this done. I'm happy to do all the work myself, but not sure what needs to be done. Is there a manual out there for this?

Hi,
Before you do the hard work, make sure you are aware that there are a few different ways to add lubricant, including:

- Automatic mixers that sit in the engine bay and insert lubricant int

Cool, thanks for the info.
When you say "half job" or "full job", does it really matter which one to go with?

Hi Guys.
To answer the original post, to convert to unleaded & I assume you mean standard (91 RON) unleaded, 2 things are needed, firstly hardened valve seat & secondly recurve the dissy to suit the lower octane fuel, to reduce pinging. As Jason says m |
If at first you don't succeed, just call it Version 1.0 |

Thanks Dr. Terry Good to hear the different ideas and knowledge when it comes to motors. Being raised around unleaded motors all my life wasn't sure on correct stages to do the changeover.

Lunchbox - the "half job" will stop the valve recession, so you won't be damaging your engine by not using lubricant. But the engine won't perform quite as well as if you do the "full job". So if all you want to do is stop recession, just fix the head.
