Will the helicoil work?

[nova_saloon]

C20xe engine i ripped out a head bolt thread and a helicoil kit coming tomorrow. will it hold?

[Jeff16v]

I would have thought you'd of need it to be sleeved instead!

[nova_saloon]

sleeved? as in press a tube in to it with a interference fit?

[mk1nova_rich]

Probably not, it won't torque up properly either

I'd sleeve it too :)

[nova_saloon]

how do you sleeve this? the way i said it would be done?

[mk1nova_rich]

Get a local machine shop to machine the block out to a larger size then turn and drill an insert, press into the block with a locking compound, then tap the thread

[nova_saloon]

naw sod that if i was going to take it out i would just rebuild the other block for piece of mind, its in the car and i am not taking it out. so helicoiling t is. if it works it works if it dont, i will just kick it and rebuild the other block

[mk1nova_rich]

Just take care when torquing it up, and should be alright. Who knows until you do it lol

[mowgli]

a helicoil should be ok.its hardly going to pull out when there is the rest of the engine round it.....

[mk1nova_rich]

I just hate helicoils TBH, we always make new inserts instead at work

Rich youve been in my c16xe what do you think of it? Oh it's been helicoiled btw at a cost of £60 lol

[mk1nova_rich]

I believe it will work, I guess I would do it properly cos I have access to proper equipment etc and have seen helicoils fail before. We do lot of repair work on CAT engine parts

Southie, yours is a bag of... :p lol

The last one that did that to me ended up with a M12 stud in it and is still going to this day !

If done propperly it'll be fine, Heli-coiled the main line on blocks at work without any probs.

[nova_saloon]
