Striped Thread in engine block

[banjodunn]

G'day no worries with a helicoil mate used one on a perkins myself about 4 months ago,not a prob as others have stated though make sure you are nice and clean and straight. I usually fit them with a light smear of loctite 277 and allow it to set then coat the thread of the bolt with antisieze and have not had a prob getting the bolts out later

Hi Guys,

Thank you for all of your help. I was unable to hire a magnet drill so I am going to make a jig as described it this thread. I will ensure I take all of your valuable advise when the rain stops.

Again my thanks to you all.

Cheers

Might want to check out the TimeSerts, many say they are superior to Helicoils.
Don't know never used them myself.

X 2, These are a step up in quality from heli-coils.

You may want to check into what size hole you need to drill. I know steel is a larger diameter than Aluminum. But I don't know much about cast, it taps pretty easily so it may require a smaller hole than steel.

Because it's a blind hole make sure you use a bottoming Heli-coil tap. Also make sure you get the correct length insert. With the head removed put the bolt through the hole in the head and measure the length of the threaded end sticking out. The insertion tool can be kind of pricey but they really do make inserting heli-coils much easier than any home made tools.
