The era not only allowed African American artists-from painters and authors to dancers and musicians-to experiment with and reinvent their crafts, it also saw popular Black artists experience and explore gender, sex and sexuality like never before. The growing freedom and expression of Black culture during the Harlem Renaissance also fueled the burgeoning drag ball scene into the 1920s. Spectators for drag balls expanded from “a few courageous spectators” in the 1800s, to thousands by the 1930s, according to a collection of essays about the balls at the New York Public Library. That drove the competitions underground (and also undoubtedly added to their appeal). By the early 20th century, drag balls were considered illegal and taboo to the outside world. Attendees varied in race, gender and sex-with some women taking part by wearing men’s clothes- but the main attractions were female impersonators who showed off their gowns and bodies to a panel of judges in typical pageant fashion.Īs these balls continued for decades, they grew in popularity-and notoriety. 710 hosted regular drag balls during the post-Civil War era. All these events can trace their origins as far back as the late 1800s. It was here where the world of drag pageantry, which often favored white contestants, evolved into competitions that spanned a variety of categories, including “vogue” battles. If you do have a leaky cylinder, a compression test should point it out within a matter of moments.In the early 1970s, Black and Latinx gay, trans and queer people developed a thriving subculture in house balls, where they could express themselves freely and find acceptance within a marginalized community. If they manage that without needing too many turns of the crank, then you're unlikely to be suffering much blow-by regardless of cause, and need to look for some other reason for the apparent problems. For the sort of issues this test may suggest, I'd much rather cut the crap and just hook up a proper cylinder compression tester and see if all the engine cylinders are reaching a good, consistent (within themselves and between each other) internal pressure, both when warm and cold. And for the most part, unless you were absolutely stuck without either the proper tools to do better and more direct tests yourself, or access to a garage/mechanic/friend or family member who may have them, it's a bit of a waste of time and nothing more than a bit of minor contributory evidence towards trying to decide between one of several different possible causes. I would expect it's something you'd only ever be driven to do if you already suspected there was something wrong with your engine or were having trouble with it, like very hard starting/poor idling, losing power/misfiring, bad fuel economy, funky smells/fumes in the cabin, excessive oil use, funny noises etc. I don't think I've ever been recommended to carry it out before. those would seem to be something that could cause the mentioned "blow-by" symptoms just by operating as the manufacturer intended)Īnyway, in terms of whether it's a useful test. the crankcase and head, and that could cause issues if they were clogged with dirty oil residue. However, I'm still a bit wary of the validity even of that, given that I've had several vehicles - mainly older ones, at least where it was obvious, probably down to emissions regs? - which had specific "breather pipes" connected to certain parts of the engine intended to equalise pressures between e.g. (The theory behind it, of course, is that either your valves, and particularly valve stem seals/collets, or your headgasket or piston rings, may not be sealing quite as well as they should, and are allowing gases to escape from the combustion chamber into the head either directly (valve side) or via the crankcase/sump or other parts of the oil system (rings, gasket). depending how old the advice is, that may even extend to simply having an overhead cam vs pushrods, but also stuff like VVT and EGR could have an influence. There's a lot of changes that have happened in the cylinder head (where the oil filler is usually, though not always located) down the decades which might make noticeable air movement more likely than it used to be. I'd also wonder if this rather traditional/old fashioned test is entirely applicable to newer vehicles.
