5.3 Silverado oil leak- HELP!!
Hello....I have a 2006 Silverado 1500 4x4 with a 5.3 motor and there is a oil leak coming for the rear of the motor. I have changed the oil pan gasket, with a felpro gasket and used the black RTV in the corners where the seams are, but its still leaking. I have oil from the bottom side of the starter bolts (the starter plastic cover has oil residue) going across the bottom of the pan to the side with the oil filter. The filter has drips there too. I do not see oil coming out of the trans hole that is at the bottom (and I do not see oil residue on the flex plate) so I do not suppect the rear main leaking. I have also looked at the valve covers if they leak, nothing found except loose bolts at the front of the motor. The oil pan bolts are tight, the 2 x 15mm bolts are tight, and the oil filter is tight. On the drivers side of the block is the block off for cooler lines and that is not leaking. I did feel behind the heads for oil, nothing. The oil pressure switch has been changed, but not leaking.
Please help!

Thanks...I wiped it all down, didn't see the source. Getting my hands on a smoker and will place that in the oil fill neck and use a rag to seal it. Then look where smoke comes out. Will let you know. Thanks again

That may locate it.Those can be up and behind things. Hard to see.
