So the other day I was installing a new throttle body and noticed that the Evap N80 port, where fuel vapours are pulled into the intake tract, appeared to be leaking some crap as shown in the stain in the picture. I am by no means an expert and there no codes being thrown but this simply does not look right?
I understand that these systems have been around for 10-20 years so thought I might be able to get some advice on this.
