For the temperature gauge not reading right that is usually down to a bad earth. Maybe the sensor or other bolt between the sensor and block has built up enough resistance to give issues. Took us ages to figure out that one on my dad's Massey Ferguson when we couldn't get enough cranking amps into the starter. It turned out to be the big bolts holding the gearbox to the engine block

Just make sure not to keep any receipts for the rebuild

If you have oil built up in your exhausts it could take a fairly good run to burn it all out. I once flooded the pants off of the starlet when I first did the EFI conversion and it was smoking like crazy so I did a compression test and got 0. Engine was actually fine, I probably just tested it wrong

What drove you to do the compression test? Was it running badly or something?

Sounds like a 4K with 7/8 race cam in it is your best option. Rebuild kits are like $150

Best bodge i did was using high pressure hose from the cowshed as radiator hose on my corolla back in the day. Was still going hard years later when I sold the car.

I don't really do much machining for others anymore. Mainly just make plates at home or otherwise focus on day job That (from the little available info) looks like a pretty tricky job. Also safety critical so I would steer well clear

No way around it now. Gotta pay to be the boss.

Newest versions of freecad are perfectly good for 95% or more of what most of us on here would need. Still a learning curve but it is getting better each year

Sounds like the backlash is just being taken up and released in the diff. It's probably the caliper on the other wheel that is occasionally grabbing as the axle turns. Sometimes the piston in the caliper doesn't automatically retract slightly when you let off the pedal, so you will get light rubbing. That can be caused either by internally swollen brake hoses or worn o-ring in piston bore. The o-ring is designed to deform under pressure then pull the piston back a bit when you let off. Light rubbing is always louder than heavy rubbing

Make sure to use proper EFI hose clamps or the cert man will ping you

The thing that caught me out once was my roller has two grooves, one for small wire and another for big wire. I was running big groove with small wife for ages and always got frustrated with it being intermittently crap. Flipping roller over fixed it

Magnesium is fine to machine. Main thing is to keep the swarf dry
