Fuel Injectors o-rings ripping??? Anyone no why???

[zippe]

Ok i have a Sr20det redtop and on cylinder # 2 the lower injector o-ring keeps ripping on me causing fuel to leek and cause a rough ideal and a miss fire.

What I have done is switch the injectors and it rips it on every one.. I have change the o-rings 3 times and always lubricate them…I pulled the fuel rail off the car and looked at #2 and #4 and the rail look the same on both cylinders.

Any Suggestions????

this is a common problem when installing nissan injectors-make sure and use lots of lube-vasaline or some other type of thick lube-check your port for any obstructions or possible scoring from removing old injectors-make sure that the opening is clear of any debris-other than that you should have no problem installing-good luck

I got the injectors in... and so far no leek. i cleaned the fuel rail very well and used a lot of vasaline and it worked a lot better Thanks
