Been to the gm dealer 3 times, they say they can't duplicate the ticking/exhaust
leak sound I sometimes hear,one says detonation, another say use high octane gas,hope you can help me.
JA: What part of the car is the leak coming from? What color is the fluid?
Customer: No fluid, it sounds like an exhaust leak/ticking sound
JA: What is the model/year of your GM?
Customer: 2011/5.3/1500 2wd gmc
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I have taken it to the dealer and they say it can't be duplicated,do they have a service bulletin on this GMC?
JA: Anything else you think the mechanic should know?
Customer: No,I like the truck,in fact the best truck I ever had.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the GM Mechanic about your situation and then connect you two.
