    Injectors install problem

    I bought some DSM 450CC on ebay and i have some trouble installing them. I got a vacuum leak at the lower o-ring on 1 injector. I have bought new o-ring and the problem is still there. The injector seem to be firm in place ..
    I'm just wondering if someone fixed a problem like that.

    Some silicone? Or is that a bad idea?

    Terrible idea putting those wheels on…

    Yeah, that is a bad idea. No offence

    Basically you just gotta get them to fit right. Are the tabs the hold them in place still good? Did you get rid of the little plastic block that spaces the tab from the lower manifold? If you got rid of that it would give you slightly more clamping force on the injector possibly sealing it up.

    It was running rough the last time i started the car. I didnt installed the distributor correctly. Now the car is idling great and i dont hear anymore the vacuum leak around the injector.

    thanks for the help..
