......
some of the item Ive fitted them to are so delicate after stress and crack detection that if you dropped it from about 30 mill to your desk just put it in the bin scarp plus when hard anodised this can affect it to so off it all goes again to be xray-ed for material defects and sample pieces are sent to check the rockwell hardness

They don't need to be delicate if they're painted Battle Ship Grey and are going to float!      

absolutely

these are the machines i work on to make these components

.......  Helicoils are used in performance race cars as it provides a reliable and a strong thread....

Perhaps I should strip my engine down after each major use ....... they do on race cars!  

Precisely - the fact they are stripped down time and time again shows the resilience of the helicoil!

You stick with your networks & I'll stick with Timecerts!

US aircraft obviously like to use Helicoils. I admit I've only ever fitted a andfull of them in my life, but IME the Helicoils I've come across have often unwound out of the helicoil tapped hole.  
I've had better results with the solid one piece Timecert thread repairs. What have you fitted them to where the slight expansion of the bottom of the insert has damaged the component? I've generally used them where I've repaired or beafed up a thread in ally.

i think time-certs being solid are just to heavy as the coils we use are titanium set in beryllium

screw thread inserts/heli coils

Interesting!

Helicoils are crap at the best of times on items that will be fitted & removed at various times, not too bad if it's to be fitted & left in, they have a tendancy to wind themselves out. The lower sump pan is only pressed steel with an ally threaded ring pressed into it. It's this female thread that's likely to be fubar'd.
I agree with Daz/Loo Knee regarding replacing it, they're not that expensive new, a 2nd hand pan will be even cheaper, and held up with a handfull of M6 bolts & grey sealant.

Disagree strongly.  Helicoils are used in performance race cars as it provides a reliable and a strong thread....

the reason we don't use them is that the last three threads that are used to hold the certs in can distort or stress the surrounding areas causing the item to be scrap!

they both have there places and we just don't see eye to eye but the input has been good input and that can only be a good thing

i will bight my tongue in future before going on one i apologize

obviously not installed correctly then if the right compound is used to secure them in place there is a molecular bond created which is as strong as surrounding components

or you could remove the sump drill and re tap to a larger size get a screw thread insert and put that into the larger thread you made in the sump and that will bring it back to the original size now re insert sump plug job done

                http://www.emhart.com/media/win/helicoil.wmv                                                   

a bit of a longer way round the problem i know the up side is the new thread wont strip any where near as easily being made from a hard stainless steel i have done this on past cars to all the spark plug threads works a treat the same is done on some aircraft parts

(make sure to remove any/all swarf/particles of metal before re-fitting the sump)

just dont like the thoght of putting in paperclip in the wrong pins and poohf goes the ecu

Put it in the right holes then

If you are using it a lot, consider buying an OBD plug, and shorting out said pins, then you just need to plug in your plug, and watch light on dash.

i would intend on putting the clip in the right pins but i all ways save some space for error
