Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The O rings on the injector will not cause the engine to leak oil but if they are leaking they can cause a fuel leak. That being said, the valve cover gasket as well as the intake could cause the engine to leak oil if in fact they are bad. Where are they telling you the leaks are coming from? Post back with full details and I will try and help you with this.
