Slant 6 Truck Dipstick And Tube
I have a couple of shots handy this morning, and I can get better ones after work if you need them. Here's the first, still in the truck from when I got it. The green arrow shows a bolt that goes through the left motor mount to stabilize the tube. The tube is really long, like 2-1/2 feet or so.
Here's another after pulling the engine, but clearly I disconnected the tube for removal and it's just sitting in the hole in the oil pan. It's oriented over by the carb now instead of pointing towards the battery.
If these aren't good enough let me know. I still have the original tube in the truck, but I did have to re-shape it a bit to clear the headers, and I know I cut off about 6-8" because it was too long and just hanging out in the engine bay.
