That’s the first time I’ve ever heard of someone saying they had a problem running Red Line’s cleaner. I would say your experience with Red Line’s fuel cleaner; presumably SI-1? Was rare and likely not a problem with the product itself. It’s got a great reputation and many users that have and continue to use without issue. I’m not sure what exactly happened in your experience tho.
It's not really excessive flow on a DI engine it's improper atomization. Direct injectors spray a very fine mist like a diesel injector, if there are deposits it sprays droplets, and since the fuel is injected directly into the cylinder after the intake and compression stroke there isn't any swirling of fuel going on like in an intake manifold port injector. At 200 psi of compression and 1000+ psi of fuel pressure any liquid fuel that doesn't burn goes right past the rings and into the oil.
Sometimes. I've had DI cleaned and tested that simply out-flowed a new injector by 10+%. This was post-ultrasonic cleaning, so no deposits. End of the day they are mechanical devices and do fatigue.
Well, these were two Bmw engines, low compression, (us spec in other words) with rudimentary fuel injection and no knock sensors. One was an M20 and one was an M30. They both exhibited the same behavior, pinging under load where they had never done that before. Neither engine did that with Techron or even SeaFoam in the tank to clean the injectors. This combined with many poor experiences with Water Wetter has dissuaded me from painting all RL products as excellent with a broad brush. I still use some of their products. But I do not use all their products indiscriminately. Perhaps the formula has changed since the mid/late 90s when I had this problem.That’s the first time I’ve ever heard of someone saying they had a problem running Red Line’s cleaner.

Thanks for sharing your experience, Apparently, those seem to remain isolated incidents, as given its wide use and popularity here I would think this isn’t a concern 30 years later. Can’t recall hearing anything like this myself before and this wasn’t something recent. Not saying your experience isn’t valid, just important to understand its context for today.
Motorcraft purge valves are hot garbage. It’s a total coincidence.
Does it have an aftermarket tune or any mods done?
Stock except for a turbosmart 50/50 bov with boost reference adapter.
