Striped spark plug hole

My 97 has a striped spark plug hole in the #8 cylinder and the shops I have talked to say they have to pull the head to put the heli coil in. Thinking about pulling the head myself and bringing it in to have the coil put in to save some cash. I have pulled heads on older trucks is there much more to pulling one out of these newer trucks?

you have to remove the front cover and intake,the egr tube can be a pita,also be carefull not to scratch the block surface and don't overclean the surface.(don't buff untill shines)

Isn't the egr tube (it's brand new) on the drivers side? The plug hole in need of repair is on the passenger side at the back, I was told it is #8 but that could be wrong. Any tips for removing the front cover? Thanks for the quik reply shelby

So it's the #4 cylinder and not the #8 (won't be going back to that shop) What would be better and what would be easier. Checked out timeserts online and they seem too pricey. The shop that did the last bit of work on the truck said a heli coil would be best. What would you recomend. (you never steared me wrong in the past)

I have untill Oct 15 to get this truck on the road and am on a tight budget as usual lol But not as tight as usual

helicoils work in a pinch but because they are stainless they expand at a different rate than the aluminum head,timeserts are made of a material that expands at the same rate(copper alloy)they last longer.

Re-Tap

How steady are your hands? There is a method to re - tap your plug hole while still in the engine bay. Make sure the piston is at bottom of stroke,and coat your heli tap with heavy duty bearing grease. If you have steady hands you can re tap at the right angle for the first 3 turns. After that half a turn then remove,wipe off the grease and replace with fresh grease to make sure no cuttings get inside the combustion chamber and the oil rings.So ,1/2 turn ,clean and re-pack until you have enough threads for your heli-coil.put in your insert,replace the plug and wire ....your good to go!
