Arghh...Need to invent a fix. Advice?

I've got my AQ131A on a stand in the garage and while turning it over to access the oil pan bolts, I broke the oil dipstick tube right at the block.

Replacing it would require first finding a replacement for which I have little hope and then somehow knocking out the remnant left in the block.

So, I'm wondering if I could combine a bit of spot welding and JBWeld to re-attach it to the block? I don't think that there's much, if any oil pressure there and the tube is well supported at it's other end.

Any opinions?

I seem to remember that the stub needs to be knocked out from below by removing the sump, which I am assuming you would rather not remove. I don't think I would trust JB weld cause if it fails it will be awfully messy.
If the dipstick is not too wide you might be able to fit an internal sleeve that is an interference fit and as you can see how far you can allow it to penetrate by measuring the distance the dipstick goes into the sump, make it long enough not to allow oil to splash up to the joint. I'm sure that some oil/heat resistant adhesive would help too.

its a bubble flared tube pressed into the block. you could attempt to tig weld it, however would be easier to remake it using brake line and brazing on a ring where the flare was, or if you have the right flaring tool, make the whole new tube.

as far as removing, a few taps with a chisel and hammer will deform it enough to come out

It looks like the pan is off in your pic. Look under there and knock the tube up from the bottom until it can be grabbed with some vice grips or pliers.

Quite a few of them on Ebay for around 50-60 bucks +shipping.

I do have the sump off and can knock out the piece left in the block. I rather like dypcdivers suggestion of a inserted tube except for being concerned about the oil stick hanging up on the upper lip of the inserted piece. That, plus the fact that the oil stick is a pretty tight fit.

Maybe fabbing a new piece entirely would be the answer assuming that I can find the right diameter brake line. I'll take it into the local auto parts store and see what I can find.

Worst case scenario is ebay although I didn't find any today. Will check again with different search terms. Thanks for the answers.

Got the little bugger out. Since I had the pan off I was able to bang it out from underneath with a drill bit that happened to fit into the hole and lay up against the piece itself. Two good wacks and out she popped. It's only about an inch long.

They make aftermarket electronic oil level sensors for cars...

Re: Arghh...Need to invent a fix. Advice?

Who cares if its not marine approved? Power steering pumps aren't but they get used. Temp and oil gauge sending units are EXACTLY the same part numbers as automotive with no specific 'marine' reference. The only thing I don't like about oil level monitoring is they don't seem to be accurate. However I can say in my experience they can keep you from running dry which is okay I suppose. Just find a dipstick tube and stick that fits, cut the tube and dipstick or use current dipstick and cut used tube to fit. Doesn't have to be perfect, it just has to let you know that the oil level is okay or dropping. Really, ANYTHING that fits and looks good is fine as long as it allows you to monitor the oil level. I've had to use long curved dipstick tubes from completely unrelated engines with a flexible spring type dipstick for custom installs. Looks factory and perfectly functional. You can buy dipstick tubes everywhere, don't get stuck thinking you must have that size. A tubing cutter will make it good. Why not customize it so when you lift the engine cover it is right there where it can be easily seen and reached. Then maybe even find one of those long curved oil fill tubes from a van that can be positioned so an oil fill cap is right next to the dipstick and filling oil up is easy. I've also custom made them so they are right next to closed system antifreeze overflow bottles, along with a custom power steering indicator glass. Custom big block installs in small engine bays makes one get creative. Did a 454 in a Chevy Vega once, man that was a sweet one. The entire rear hatchback area was fender wells for the tires since rules stated tires could not extend past fenders on the outside. Think about what you would really like in your application, then think about what each individual obstacle presents and how you can work around them. Ya'll be surprised at what you can come up with. I've seen such ingenious and simple fabrications I've wondered why I didn't think of that. And when it looks sharp you'll feel really awesome every time you see it.
