Slant 6 Turbo 68Dart Project
Punched the pan, just like I planned. What a stressful part of the build. I would not recommend doing this with the motor on the car to anyone else. Too nerve-racking.
Congratulations on successfully completing what is arguably, the trickiest, if not most difficult, part of this build.
I have done two of those, both in the car, and I am here to tell you, stressful is the key word.
The first one I did was the drain for my Vortech supercharger I have on my 360 Magnum in the '72 Valiant. The drain-setup is identical to a turbo. I had
no room to swing a hammer for the punch, on the side of the pan, so I decided to think outside the box and punch the drain hole for the fitting, in the horizontal floor of the oil pan, pointing upward, near the front, where the floor of the pan is high; just barely lower than the pan rail. Well above the level of the oil in the sump. The supercharger, the source of the oil being drained, is high enough that the weight of the oil in the line coming out of the bottom of the blower, forces the oil through the upward-pointing fitting in the pan, and I have had no problems with this setup. Knock on wood...
The slant six/turbo drain-fitting placement is identical to the one you have just fabricated, but that hole was punched, too. I had a long, skinny, slowly increasing-in-diameter punch that increased from an eighth of an inch to just-smaller than the fitting size. The fitting cut its own threads, so the fit was tight.
I hope I never have to do that again...:banghead:
