Lack of correct clamping pressure can lead to the injector seal not working properly , also leading to the smell of diesel fuel . Once an injector has been removed , I try to smear a very thin coat of Febi ceramic grease on both sides of the seal and along the injector body to A) stop the seal falling off during install B) allow the seal to move / deform during clamping c) stop any steel / alloy bonding occurring during use . Read up on seized common rail injectors & their destruction during attempts at removal . I use the Febi stuff as it does what is says on the tin , Really does work at very very high temps , used on a turbo actuator shaft that had seized due to heat & corrosion

Okay you guys convinced me. I'll clean and reinstall all injectors correctly. Ordered 5 OEM mounting kits. Also bought an injector cleaning kit to clean holes as best as possible. Thank you for the ceramic paste tip, I'll definitely do that.

What are the torque specs for clamp bolts? I searched online and found 28 and 13 nm, which one is correct?

Life's too short so I bought the tool as for me, Euro 3 circlip removal and installation is a real pain.

That's what I've decided too. Just ordered it at a Volvo dealership for 84€.
