    I used to use a piece of TV roof antanae rod with a baby nipple on the end! :clapping:
    Always made me a little nervous around rotating parts tho....one slip and that rod comes out the opposite ear!! :bang head:

    Does this bearing look fully seated?

    Doesn't want to seem to go any lower.

    Yes I believe that's right. One way to tell is once you install impeller and shaft if everything isn't seated properly you wont be able to get snap rings in.. its been awhile since I did this but I know it wasn't hard to install bearing so I believe its seated

    Well, that was quite the adventure for me, The Noob Wrencher. I'd been hesitant to open up the engine before, but I had all the parts and figured I'd save a few hundred dollars doing it myself. It wasn't too hard with the Haynes book and this how to guide.

    I had to find and buy a 26mm socket to drive in the mechanical seal. I could not find a phenolic gasket scraper anywhere, so I had to settle for some gasket dissolving spray and very carefully using a metal scraper thing(awl?)

    I also flushed and changed the coolant. Nothing leaking now, so it seems I did it right. :)

    I typically use a razor blade even thought its not recommended. Works just fine if you are careful.

    I follow up with a scotchbrite pad if needed. You need to be careful though because its easy to remove the paint just at the edge of the casing when using the scotchbrite.

    I have fashioned a plastic scraper from an old cutting board. I just take it out of the kitchen and tell my wife its time to buy a new one. It doesn't last long though. You need to sharpen it often.

    Oil with water like cream from the overflow on the garage floor after a 100 mile run. no lose of power. Head scratch how there is no water in the sump. Could only be from the water pump seal leaking? This forum confirmed my guess. Thanks for the confermation and confidence to do the repair.

    Typically it's from the waterpump seals/bearings going bad. There are other places you can get it from with orings and misc but that's where i'd start.
