    I understand I just need to remove a bolt and clip to remove tube and replace o ring.

    What is the easiest way to reinstall? Access through the passenger wheel well or just get it up on ramps?

    Also hope I got the right oring - 10mm ID, 14mm OD and 2mm thick.

    Any tips?

    While I have never done the dipstick tube in a 5.7, I have done it on other vehicles and equipment.

    They have all be relatively the same, remove clip/bolt holding it to the block and pop out the tube, install o-ring and put it back.

    Looking at my truck, it seems getting it out can be done through the passenger wheel well. But getting it back in will require being under the truck.

    It pulled right out. I ended up putting on ramps and could access. The old oring was flat as expected.

    The oring I listed above is the correct size. They sell them individual at Advance if anyone needs one in the future.

    I also took some Permatex ultra black and put it around the tube to seal it up. It appears this problem is solved for now. Not bad for a truck with 235,000 on it.
