volvo 850 1993 injectors o rings
i changed the oil trap in my volvo 850 and changed a bunch of parts while i had it apart. i ordered a o ring kit for each injector but i am not sure how you change the bottom o ring and plastic washer. do you take the injector apart? help please:)

Are you serious..... Post this in the 850 forum
|
yes i am serious a hole the kit came with two rubber o rings and a plastic washer that does not fit over the end of the injector. if you dont want to offer any kind of help mind your biss

Have to take your injectors out of the fuel rail and you'll see the rubber O-ring there. Not sure about a plastic washer though. I have some injectors at home that I can take a picture for you if you like.

all I was saying was to post it in the 850 section... You posted it in forum issues or something at first.. That was my only point.. And yes I am an A-hole but by birth not by choice...
The end caps sometimes need some encouragement to come off but they do come off, If you dont have replacements for them I would NOT try to remove them cause they usually get destroyed when pulling them off.. The o-rings, spacers and seal you speak of can be found at Napa locally for about $3 to $5 for the kit spacers and all here is the link ----> Store Locator | NAPA Online and or ---->Store Locator | NAPA Online or FCPGroton online but its only the o-rings ---->1993-1997 Volvo 850 Fuel Injector Seal Kit-contains upper and lower o-rings You can also get the kit from the dealer but they most likely WONT have it in stock. the part number for the volvo kit is----> 1346393 |
seal kit and ends.
The o ring seal kit i got has a yellow washer, two o rings and a blue plastic cap looking thing. what is the cap for?
Also, I was having problems fuel spraying all over my engine compartment and replaced all the o rings but not the yellow washer. the nozzle end of one of the injectors was loose. would this be the cause of the leak? Where could I find a set of the seat seals. I have not been able to find a replacement for one that was missing. The injector with the loose tip was the one with the missing seal. someone at some point used heater core hose to make another seat seal. any suggestions would be greatly appreciated. thanks. --94 850 non turbo 250k-ish |
I had my injectors out last week on the '94 and really there was only two O rings involved. One on the top and one on the bottom. Most Bosch injectors have the pintle caps but on my '94 (yellow injectors) there were none.
The last injectors I had out before that was on my daughter's old Porsche 944 and they definitely had the pintle caps and the replacement caps were a bear to get on. ...Lee |
There is definitely a yellow washer on the bottom of the injector and it definitely wont fit over the lip on the nozzle end.
The real problem is the end being loose on the Injector. I will take some pictures and post them tomorrow so everyone can see what I am talking about. |

I understand the concern about the loose end but usually it's just a matter of using a little Vaseline on each of the two O rings and muscling them in. |

Here is a picture robbed from unnamed parts site to show what I am talking about.
The black and white one looks more like my injector, Bosch part. Note that the nozzle tip on only one of my injectors is loose, not disconnected just loose. https://volvoforums.com/forum/attach...1&d=1319651462 This color image shows the blue cap that i have in my o-ring kit. this is not a bosch injector though. You will also see the yellow plastic washer in both. This washer will not slip over the tip on my bosch injector. https://volvoforums.com/forum/attach...1&d=1319651566 |
The mystery is can you replace the yellow washer? how? does it involve removing the metal stock tip and replaceing with the blue plastic one? OR Does it matter because the issue was actually the rusted out fuel pressure regulator?
I guess I'llk be sending that new injector back to the parts guy. |
I've replaced the O rings on a lot of injectors but never done the yellow washer. The kits I've bought from BWD or Standard or NAPA only had the rubber O rings in them. I'm curious now too.

One more thing on this too. The opening on the blue cap is substantially smaller than the opening on the metal end of the Bosch injector.
