I have an 02 z71 with the 5.3 in it and i have developed an oil leak. Get under and clean all the oil off from everywhere and then drive it and come back and oil is running down the side of the filter. Just replaced rear main seal about a month or two ago. Anyone have any ideas or had the same problem. Let me know please. Thanks

Could also be the filter is double gasketed. I have seen the gasket from the previous oil filter stay on when you remove the filter.

checked that first thing. didnt seem to.be the problem. When I.had the rear main seal replaced it stopped the leak for a little while. drove it on a 500 mile trip and noticed a little drop of oil then gradually got worse

The adapter is easy to replace and is less than $10. Part number is 12552357. I would remove the filter and inspect the adapter to see if its damaged in some way or not allowing the filter to thread completely on. Maybe the adapter is ok but loose. Also make sure the surface where the filter gasket rests is not nicked or otherwise damaged.

There is a plate above the oil filter that is known to leak fairly often. It is held on with two bolts and is easy to get to. There is a thread on here about it that includes pictures.

Thanks for all your input on my oil leak problem. I have another question, When driving across rough places or while turning the steering wheel i can hear a popping sound in my steering, it has done it since i have had just wondering if anyone has the same problems or knows what it could be.

Lol!

OP, check your wheel bearings and upper and lower ball joints also.
And don't forget about the old intermediate steering shaft, a constant problem with a popping sound for your year model.
