The evil side of carb cleaner (ruins seals)
A few weeks ago I posted a thread and DIY on isolating vacuum leaks by observing the O2 sensor while spraying small amounts of carb cleaner at suspect areas ( http://www.peachparts.com/Wikka/M103VacuumLeak). This technique worked very well, however I suspect that the carb cleaner actually ruined the injector seals and O rings. I would recommend using WD-40 instead.
When I first did the procedure I found only one leaking injector and repaired it. A couple weeks later I repeated the procedure and found that other five injectors were now leaking. I can only guess that this was caused by the carb cleaner. I tested the carb cleaner on a few substances and found that it will soften and dissolved cured silicone (RTV). So I just want to pass on a warning: be careful with the carb cleaner.
