I am rebuilding a couple of 1991 B230FTs that were cast before the piston cooling oil jets were in use. I intend on machining the oil galley to accept the Volvo jets. I have never been able to find an open 93 or later engine to see whether they are mounted forward of the connecting rod (in line with the front of the cylinder), or behind it.
I'm sure the Swedes did some testing and decided one location was better than the other, so I'd like to bolt the sprayers in the same place.
Does anyone know the torque value for the hollow bolts?
I even bought the Volvo Green manual for reconditioning the B200/B230 engine for this info and there is NO reference to the oil jets.
Somebody here must have been into one of those blocks and know the answers.
