What happens here

Locate the ideal spot on the oil pan for the turbo oil drain. The host considers several locations, including where the stock Escalade drain was, but settles on a flatter section. Secure any loose wiring near the drilling area with zip ties to prevent damage. Place a paper towel or shop rag inside the oil pan (through the oil filler) before drilling to catch metal shavings. Use a small drill bit (e.g., 1/8 inch or 3mm) to create a pilot hole, then gradually enlarge it with a step drill bit until it reaches the desired size for the 1/2-inch NPT pipe thread. For the final widening, use a standard drill bit to ensure the correct depth, then apply a cutting fluid before using a 1/2-inch NPT tap to create the threads. Be careful not to tap too deep.

Goal: Create a threaded hole in the oil pan for the turbo oil drain line

Tools and materials

  • 1/2-inch NPT Tap — Creating threads in the drilled hole
  • Cordless Drill Milwaukee — Drilling pilot and main holes
  • Ratchet — Turning the tap to create threads
  • Small Drill Bit — Creating the pilot hole
  • Step Drill Bit — Enlarging the pilot hole to the desired diameter
  • Zip Ties — Securing loose wires away from the drilling area
  • Cutting Fluid WD-40 — Lubricating the drill bits and tap
  • Shop Rag — Catching metal shavings inside the oil pan

stick it in there and start doing stuff just made the kind of the starter hole with a smaller bit because that big one would take a while and it would walk around so when you can starting your hole with a smaller drill bit that locates it much more precisely don't want to get my wolf aircraft hat dirty if you're wondering what wolf aircraft is that is the place that i get all of my stainless and aluminum from for like tubing header kits all that stuff american made awesome people would definitely recommend if you're going to build a turbo kit out of like and you want high quality stuff time for some wallering we're going to find out if it needs to be wallowed because it maybe it won't actually let me see if i have a step bit in my box i got a lot of things the step bit is not one of them i know some of you guys are sitting there going to be like this way to do that i know okay if you know the rules you're allowed to break them i think i heard that somewhere i don't know that's my rule i just made that up if i didn't hear it somewhere we're just gonna do it anyway i just want to see how that lines up that should be okay i just don't actually make it too big before i commit because i'm worried that the thickness of the pan is thicker than the steps in this bit problem i'm running into is the thickness of the pan is just a little bit thicker than the step depth so it's the right size to bite but it's going to want to run into the next one which is going to take out material material that that fitting needs to seal against so i think we're going to go back to a regular drill bit and do some precise wallering of the last little ridge in here actually i wonder if this will work this just keeps getting uglier and uglier by the minute of like the absolute long way to do everything and it could just stay between the two of us and this camera and you guys would never ever know but i'm not doing that i'm showing all the ugly just for you it does like that kind of that edge is like gone yeah i think we got it i know you're supposed to have one of those t-handle thingies i don't have one you have more patience than i do i'm just running it enough so the threads are like biting the whole way the threads have to be deep enough for it to get a good foothold on it but not go too deep on the tap otherwise the fitting will not have enough taper to dig into couldn't find any pipe tape
