    I bought a new dipstick tube and stick for my truck. 283 Chevy Small block. I could not get it in, then I noticed why the tube was probably missing in the first place. The old tube was broken off in the block. Got any ideas on how to get the old portion of the tube remaining in the block out? I'm looking for a way to grab ahold of it and extract it without leaving shards of metal in my oil pan.

    I would thread a self tapping screw into it, pull it out, and change the oil, with a magnetic drain plug thrown in for insurance.

    Push it in. That's what the pickup screen is for. :D






    Hahaha I'm KIDDING. Don't do that.

    Can't grab it with needle nose pliers? Isn't this causing a big leak?

    Find a drill bit that's a close fit in the remaining piece and use that to see what tap is close. Fill the hole with grease, run in a heavily greased tap to about 3/4 of the depth of the piece, and substitute a bolt for the tap as a handle. Do not pull on the tap itself, or your weekend will not be worth living...
    If there's a straght shot at the thing, use a piece of all-thread instead of a bolt and make it into a slide hammer.

    Nope. cant get it with needle nosers. No big leak...yet. I put in a new oil pump and pan when I noticed it. I've got 4 quarts in her now. My plan was to put the dip stick in at 4 quarts, drill a hole in the stick, but in the 5th quart, drill another hole at the new 5 quart oil level, but...then I realized why the new tube would not go in, and never did put in the 5th quart. Haven't been running much, but no oil is comming out when I do fire it up. It would probably leak if I don't put in the new tube and add the 5th quart and drive her around a bit.

    Bruce, you rule! That sounds like a plan.
     
  8. I had this exact issue on an old 283. A 3/8 coarse thread bolt was just right to thread down into the tube piece, no tap or anything, just turn it in. Then use the bolt head to pry it out, mine came right out.

  9. Don't put a drill bit anywhere near it unless you want to pull the pan.

    Take a bolt, I think it's either a 5/16 or 3/8 NF that works on a SBC.... put it in the hole, whack it a couple times with a hammer, and then use a socket and ratchet to screw it into the tube. Then, grab ahold of it and pull it out. Us a bolt that screw into it at least 1/2" or more.

    I've done this several times, and it works like a charm. Ask 38Chevy454, I did it on one he had busted off in his 283.

    Yep. OK. Thought about it and I'm doing it your way.

    Excellent solution guys!
    Not to put too fine a point on it, but slightly beveling or chamfering the end of the bolt (like you were going to put a point on it) would help it get down into the tube and get it started. Then start screwing it into the tube and the threads will bite.
    Kinda like a self-starting screw.

    Dont forget the fresh oil so there's nothing in the pan from working on it. :)

    Ive always had good luck using an easy out...tap it in, turn counterclockwise and the broken portion just spins right out.
    Also, you cant just push in the broken part because small blocks also have (should have) a lower dipstick tube which is smaller in diameter that keeps the dipstick away from the crankshaft.

    OK I got a 3/8 bolt screwed it in fine. But I'm just not able to pull it out. Are you just using a normal bolt? Is there some sort of puller tool or pry-bar or something I should be using?

    If you use a piece of redi- rod about 2' long and put a large headed nut on the end , you should be able to slide hammer the piece out.

    Let me clarify that a bit, Think slide hammer! Use a 3/8" redi-rod about two feet long and screw it in the tube. Place a piece of steel with a hole thru it over the redi-rod, place large washer and nut on end of 3/8 redi-rod, and use it like a slide hammer to remove piece of tube. GOT IT!

    Well no luck yet. Did the long bold / slide hammer thing,...may try again with a bigger hammer, but I'm thinking of also buying an easy out and giving that a spin...

    Thanks to all you guys for helping me out on this.

    Who ever named the Easy-out had a sick sense of humor. I'd stick with the slide hammer approach or use a small chisel to split it.

    I'm glad I'm not a dumb as I think I am. I also thought of trying to split it with a chisel. I think it will be OK to do so as I believe the hole in the block is wide near the top to accomidate the dipstick tube and narrow farther down, to just let the stick past.

    Just tried this with 3/8 bolt made into a slide hammer. Worked like a charm. Thanks guys!

    Thread in a piece of threaded rod. Place a socket over the rod, place 2 or 3 washers over the top of the socket and run a nut down. The socket will act as a puller.

    That's what I did, but I also welded a loop on the head of the bolt and used a slide hammer.

    Drain the oil.. Knock it through.. Use small magnet through drain hole to fish it out...
