Nah, not stripped. It just threaded out with the nut. Threads back in cleanly but I don't trust it to stay. Loctite it is.

Obscure parts are obscure. Anyone know what the "sensor" on the radiator side of the air filter housing is? In the picture below, it's above the red oil dipstick but attached to the housing. A cable with a plug runs from the AFM connector bundle around the housing to it.

Finally figured it out! Barometric Pressure Sensor. How critical is that in Atlanta?!?

You mean barometric correction? It's not really that important if you don't climb altitude much.

Looks good! Needs something to contrast all the black though, like the roundels in the top pic.

So 5 months later we're back to square one. It runs like shit but it runs! At least the engine looks better.

I gotta put a few things back together - put the hood back on - and then I'll play with tuning it a little. Even though I've replaced a bunch more stuff, I still think I have a vacuum leak. Smoke and compression tests on the horizon.

I hate tracking down vac leaks. M20s have so few spots to fuck up. I remember one time it was the bitch tube and I didn't realize it till I got so mad that I took the intake off to replace the gaskets.

Compression test should be first order of business. People tend to put it off because they're afraid of what the results will be, lol.

Agreed. Comp test is so stupid easy to do too.

That. Terrified.

I replaced the bitch tube seals when I was in there - which is not to say I didn't make a mess out of them in the process. Also, new check valves and vacuum hoses. The brake booster connector could be the issue or the booster itself. So I pumped the brakes while the engine was running and it increased the RPMs, I'm guessing that's a pretty good indication that there's a vacuum leak. Drove it in the neighborhood a couple times. It runs "ok" on flats and small hills but under loads it turns to crap - feels like missing but generally loss of power. Almost didn't make it up the on steep hill. Is that necessarily compression or is it possible the vacuum issues could cause that?

Either way, I'm gonna have the local BMW guy look it over. I'm just curious.
