90 degree drain elbow options

[burninman]

So back in November when I drained it, one of the cheap little plastic wing nuts broke off in my hand. No problem, I drilled through it, drained the engine, and bought replacements, that sat in the boat until today. 70 degrees out today, thoughts turn to getting it ready for spring, so I whip out my vice grips to remove the whole drain plug assembly, and CRACK. Whole frigging thing is plastic, and now basically snapped off where it screws into the block. Looking at the new one (which is metal), I estimate 1/4 inch to 1/2 inch of thread is still in the manifold. I am hoping someone else has done this and might suggest the best way to get it out shy of taking the whole thing off and drilling it out.

Ayuh,... Use an EZ-out, that fits...

That sounds alot easier than it is, at least where I'm st. I'd need a 3/4 to 1 inch tap, and the largest available at autozone, advanced, sears, ace, and lowes maxes out at 7/8. Any other thoughts?

Re: 90 degree drain elbow options

if you get it out with an easy out why would you need a tap?

poor choice of words, sorry. the easy out maxs out at 7/8, exactly the dimensions of the inside of the elbow. So it can't bite into anything.

a dremel got me through this. I purchased a bigger easy out kit, but it alone would not snap the bond this thing had, it was ridiculous!. i cut 3 places with the dremel, then tried the ez out again, and that did the trick. did some thread damage, but used some advice from somewhere around these parts and cut some horizontal slots down the threads on a piece of 3/4 iron pipe. Coated those threads with epoxy putty, then screwed it in and unscrewed it. put the new elbow in a little later on, and fired her up, no leaks!

I'd like to do the other one too, but certainly don't want to go through this again. How does one go about removing the nylon elbows properly??
