    I would say checking the crankshaft snout runout is mandatory at this point. If you don't have a dial indicator, I'm sure HF has one that will suffice. I can't see any point of installing a new pulley without actually knowing what caused the problem. IMO, I can't see a pulley hub being so far out of spec as to cause that grooving. It wouldn't likely require a puller to remove with that much slop in the bore. I'm guessing it is a bent crank snout. And even if it isn't, the seal will need replaced again after riding on that grooved up hub.

    Let's hope that the hub issue is from a previous owner, and that the current issue is from that hub being bent. No doubt the end of the crank needs to be checked.

    HI Guys,

    I will have to look up "dial indicator", I don't have one for sure. I have had the jeep about a year but it has been being worked on the whole time, it was in pretty bad shape and I not a mechanic and only have half the tools I need. I only have ran the motor maybe 2 or 3 hours total since I got everything back together. So that damage (Groove) was done sometime in the past before I had it. I know that it set up for a long time because the person I bought it from bought it to fix it up and never did. And yes I did bend the pulley some when I pulled it off originally, I don't know if it was bent before that.

    I appreciate the advise and I am considering my way forward, but the "adventure" hasn't been what I hoped. This project has required way more work/time and money than I ever dreamed and I really getting burnt out and funded out :)

    Thanks for the help.....

    I will let you guys know what I find....

    Welcome to the club!

    But bad times make good stories. We learn and we grow, and gain skills...and tools.. don't forget the tools!

    Consider this a "bonding" experience that will bring you closer to your Jeep and prouder of your achievement.

    Yeah, don't give up. When you do solve the problem whatever it is you will feel an accomplishment that will make it all worthwhile. I remember someone here saying the difficult just takes a while and the impossible just takes a little longer. keep on keeping on.

    Yep, there are very few projects, especially old Jeep projects, that don't have a few hiccups associated with them. Take a deep breath and dig in again. Keep the focus on driving that machine down the street (preferably with no top and the windshield down). It is a unique experience, bugs in the teeth and all.

    Without reading all the previous comments, did you try spinning or wiggling the fan blade by hand after the noise starts? If the noise changes it may be the water pump seal. Also, remove the oil filler cap and see if the noise changes In the video it sounds like steam and that makes sense since it starts when it get's hot.

    He has tried it with the fan belt removed. No change.

    Weird. Hopefully it's not steam leaking internally. I would think a bearing would change tone as you rev it and so would a dry timing gear. If your timing gear oiler was plugged you should have high oil pressure.

    Hi Guys,

    Well, I finally had a good day. I replaced the front pulley with a new one and the noise is gone. There must have been something rubbing on the old pulley that was causing the noise. I really appreciate all
    the feedback and suggestions they were a great help. Also Thanks for "talking me off the ledge" as it were, lol.

    I took her on a 8 mile test drive and although there is plenty of other noises that one no longer exists, water temp stayed about 140 and oil pressure went up to about 48. I made these post because this issue just
    doesn't seem to make sense to me, none the less I am glad it has seemed to work out.

    I still don't know if I will keep her when I am done, this issues along with the 100 others has really tried my nerves....

    Thanks again, you guys have been great, I am sure I will be posting more in the future...

    Awesome! That one definitely fooled me. Don't spend all that time and money and then sell it. Don't let issues defeat you. Get it fixed and keep it. :coffee::)

    Just read this whole thread and what a "happy ending", owner 1, jeep 0. Glad you were able to find and fix the problem and have experienced your first "wind in your face" test drive time for several cold ones to decompress and relax. We all have had jeep moments and the suffered the "agony of defeat". We all have learned with you! Keep driving the jeep, stay the course!

    My Jeep has been in the family for 51 years, and I'm pretty determined to stick it out. But: I know what you mean. After all those years of the Jeep absorbing off-road abuse like it was bomb proof back in the day, part after part seems to be failing when all I do is putter around town. And it seems to have the biggest problems in Spring and Fall, when I would most like to be driving around! The guys on this site talk like old Jeeps are a cinch to work on, and of course they are compared to most vehicles, but these guys generally are also experienced mechanics with complete tool sets. A lot of this stuff is still a big challenge for some of us, and I spend a lot of time just scratching my head with grease-covered fingers and saying, "What the ...?" But this community is a great resource, so I hope you feel like you have some partners and advisers to lean on. I hope I can help with a question some day!

    Just wanted and post an update and thank everyone again for all the help and advise...

    I just passed my first 100 Miles and everything is still working. The sound in the front of the engine never came back so that is good. That being said there are lots of other noises
    but I guess that is somewhat normal for a 70 year old vehicle. I gave it a it's hundred mile checkup and all the fluids where still ok. I found drips from the transfer case and the
    transmission but nothing major. I will not be pulling the trans out for 1 oz of fluid loss per hundred miles. We made a homemade cover for her but decided that driving the willys without
    a top is way more fun. (as look as it doesn't rain)

    Thanks again for having this site.
