Tapping new thread in 300tdi head??

[RJUU]

Howdy guys, wanted to make a start on replacing the head gasket today on my 300tdi defender and I stumble upon and absolute hideous sight. Whoever changed the exhaust/inlet gasket previous had F’d one of the intake bolt threads on the cylinder head. I will include a pic below, is this repairable?

Do not think your piccies have worked.

See if a magnet will stick to it.

its been repaired and helicoil fitted badly ie not far enough in the end of the helicoil needs to be at least one thread below, other wise it can try and screw out which results in it deforming

Magnet does indeed stay.

how would I go about fixing this? I’m getting the head skimmed and pressure tested I’m guessing a machine shop would fix this? And ideas on a price to fix?

they should do,if you havent got the proper extractor you pickle and bend enough towards center of the hole so you can get thin nose pliers on it unscrew and keep pickling it out

James martin ,your knowledge and help has been inspirational to many members I’m sure apart from me who regards your comments as gospel but I’m buggered if I know what the expression Is
‘To pickle and bend’ means

you have to get a fine point tool or such behind the helicoil and lever it out till you can get some pliers on it,often several times as helicoil breaks up

I was hoping your answer would start "Well, you get some vinegar ......"
