Hello, I Recently picked up a 2017 Zl1 with around 20k miles on it. Obviously worried/ Preparing for the oil pump failure. Already bought a Ktech pump and all the other miscellaneous parts to go ahead and do this myself. Well as I was looking at the car the other day I noticed the timing cover only has RTV sealing it and no gasket. My question is does the lt4 use a gasket from factory? If so I’m assuming that the timing cover has been off and the oil pump has been potentially changed already. Don’t have any record of it ever being done before just would hate to tear into if I don’t have too.
