I have had a strong gas smell coming from my enginge bay for a while now, so I decided to check into it more thouroughly, and found out my injectors are leaking out the top, not by the block but more towards the fuel rail? Anyone else had this problem and have a simple solution? Schucks told my the O-rings on the injectors were bad, could that be it or should I replace injectors or maybe just some FI cleaner.
