Turbo Miata lit on fire while driving
Was doing a pull and a cloud comes from the engine bay. I quickly pull over and it is on fire. I have a blanket and extinguisher in the trunk. The blanket didn't put it out so had to use the extinguisher.
The eBay fitting adapter from the oil feed line to turbo snapped in half and sprayed oil all over the manifold.

Weirdly, I don't usually consider Holly / Earl's to be a source of "cheap" AN hardware- I've used a lot of their stuff in the past and never really had any quality issues.
Was this one of the cast & machined aluminum 90° AN-to-pipe-thread adapters? Any pictures of the failed part?

With real AN fittings (see aircraftspruce.com), you always get your choice of steel or aluminum. On aircraft engines (the ones with gigantic pistons that cause vibrations akin to Hustler's bike seat), steel is used for anything carrying combustibles that is screwed into the engine itself. This doesn't seem to be the rule with automotive engines, but it's something to consider and definitely offers more fatigue resistance to vibrations.

I'll never do it again. Next time I'll check out your link. I agree 100% for steel fittings, I now hate aluminum AN fittings big time....

You are right, but that black soot was already there. Before the turbo I had a severely cracked stock manifold. ^that too
There was no signs or smell of exhaust under the hood in the days prior.
