Did anyone ever find a volvo spec for the torques on the stock squirters? Not the "these are hollow so only 12ft-lbs" guess. They have tapered seats, and took a hell of a lot to break loose at an ambient temp of about 80F. The OD of the threads is like M5 or M6, kind of like brake bleeder screws. My guess would be more like 25-40 ft-lbs. I'm looking at the TP30871/1 manual, and it doesn't mention them at all.
I have a 93 engine but it is not one of the engines on stands. So I will have to mess around to get the pan off, remove a squirter, and measure.I have old squirters that I dont trust much. Can the original squirter engine hole fit the new squirters you are displaying or not. I other words are the direct fit?
