Default LT4 oil leak

Are lT4's known to have oil leak issues? Mine is leaking somewhere and is burning off the exhaust. I just would like to know before I start investigating further if there are particular spots to check, other than the obvious (valve covers, etc.) Engine has just over 60k, and this has just developed in the last couple hundred miles. When I look under the car after sitting for a couple of days I see no evidence on the floor. So it is not a mojor leak but the smell sucks! TIA

Most likely the rear intake seal where it meets the block. All LT1/4 eventually leak here.
