    Looking for a seal for the front block dipstick tube receptacle in my 392. Trucks used the front receptacle. Scouts used one in the oil pan. Therefore I need to plug the hole. My engine had no seal.

    One of our awesome lightline vendors offered to send me one from a used block but I’d rather avoid putting him through the trouble if I can.

    Came across this gadget. Designed for a GM LS.

    Anyone know if the diameter will work? Can’t measure an IH dipstick at the moment. Nor do I know the diameter of an LS dipstick tube.

    Don't you have access to a lathe? If so, taper turn a short piece of brass after measuring the hole yourself, leaving enough on top that you can grab it with a Vice-Grip if you ever need to remove it. Polish well before installing, of course. :beer:

    Appreciate your encouragement Dana, but At $14.99 with an o ring, it’s simply not worth my time to fabricate anything if this works.

    What I have done in the past on mustangs is use tiny little brass freeze plugs. When you do a 351w swap the stick enters the side of the pan not through the block anymore. Just another avenue for you.

    I had the same issue w my 392, couldn't figure out oil leak then it dawned on me about front tube hole. I was going to get a plug from SSS or a small brass plug but I used a dip-tube for a sm blk chev off ebay ($11) Tube.jpg & cut it to measure oil in front sump. Looks good & functional
