Sounds to me like you mean there is fuel leaking from the body of the injector. That happened to mine too when the injector body threads weren't clean when I put them back together, or I didn't put it back together quite right, or the 2 parts of the body weren't tightened enough.

Adding to what vstech said - make sure you screw the injectors in right - I got one cross threaded on my 92 300D and had to replace the PC.
