Hi guys :(

I tried to change my non-working injector in my b230F...

1-I removed the gas lines (return and supply) from the injector track

2-I tried to remove the whole thing from the engine : impossible, the injectors were stuck in place.

3-I finally removed the track from the injectors (kinda difficult)

4-and I replaced my bad injector (the o-ring and the little nozzle were stuck in the engine, I had to use all my dexterity!)

5- the 4 injectors are in the engine, but I CAN'T PUT THE TRACK ON THEM!!!

(the o-rings seem too tight to enter in the track holes... is there a trick or what???

My car is dead in my garage for the night... anyone has a miraculous way to fix my problem???

It seemed to be so easy in the bentley manual.

CLEAN the junk out of the injector hole before you pull them. LUBE the hole with some WD-40 or a few drops of ATF. The O-rings can bond themselves to the opening but if you wiggle them around a bit, the lube can coat the surfaces that get exposed, then it'll slide right out. If you let WD-40 evaporate before you're done, re-wet the area.

LUBE the bottom O-rings before you jam each injector back in, and LUBE the top O-rings before you try to get the fuel rail on and it will all slide together like the parts were made for your car. Again, WD-40 or ATF works great. Grease stays around and just holds the dirt, so liquid lube is better for servicing.

The seal kits are cheap (about $3-5 at Volvo) so use new O-rings.
