Public service announcement for those doing DoD delete

[03GMCYukonXL]

Just an FYI, if you're doing a DoD delete, and you're using a non DoD valley cover, you should NOT also use the plugs for the oil ports. I was paranoid that the seals aren't good enough so I plugged them just to find out that the non DoD valley cover wouldn't fit properly now. This was my fix for this. I actually think maybe this is better... But I'm not expert

Well, first thing you need to do is actually install the plugs almost flush with the block if not flush.

Mine had a lip and the instructions specifically said they should not be hammered flush.

Yeah with a lip around them you would never get them flush. I have never had any with a lip personally.
