So i bought myself a brand new sct livewire ts tuner and i hooked it up on my truck. took it for a ride and obvs like an idiot i rode it nice till i got on highway and i hammered down on it. next morning i woke up and all my coolant was under truck and it had exploded all on right side under hood. took it to get looked at right away without hesitation the ford mechanic said head gaskets are blown and walked away. but i had no white smoke and did didnt look like i had coolant in oil or oil in coolant and i didnt see loss of power. so now im have to spend the 6500$ to get it fixed. but while im at it im going to get it bulletproof going through the whole front of truck. new bulky bulletproof egr. new black onxy head gaskets. alluminum head plate and headers. oil cooler. clean turbo make sure barrings are okay. all new rings and gaskets. all new filters around the truck. check the injectors. new water pump. new coolant cap cause im sure that it blew the psi and it wont hold that 16 psi anymore. but ugh that suuuuckkks especially since i just got the truck 90 days ago and i didnt have warrenty and i just replaced all the glow plugs and had to have bumper fixed after someone hit me at work. yay more problems......

 

Use only a factory head gasket.

i thought factory was on it was standard 18mm so i was going with 18mm black onxy

cause obvs the factory head gaskets couldnt take the pressure that was trying to be put through by the sct livewire ts tuner so i needed to upgrade them?

 

The black onyx are terrible gaskets. You will have failure, even with studs.

The stock OEM Ford gaskets are great, it's the junky TTY stock bolts that can't hold up. ARP studs, OEM gaskets, and have the heads decked to ensure they're flat at a machine shop. If you don't follow on just one part of that, you will have failure again.

18mm block/gaskets/heads are found on the earlier trucks, around 2006 (late) Ford went to 20mm heads/blocks/gaskets. The 20mm heads are all they make/sell now. If a truck went in for heads under warranty, the put 20mm heads on an 18mm truck. The gasket kits come with little step dowel pieces to put the 20mm heads on the older trucks. It was part of the parts commonization with the 6.4's.

DO NOT go with black onyx gaskets.

 

Not necessarily blown gaskets, romping on it too hard will push the EGTs to the point of flash boiling the coolant, ESPECIALLY if you have a stock coolant cap (they are notorious for causing coolant puking). Black Onyx gaskets are absolutely JUNK, I've heard of 6.0s popping B/O gaskets with studs in place just as much as stock gaskets with TTY bolts, go ARP studs with factory Ford HGs. If you legally can, get that EGR cooler out of there ASAP, otherwise put in a BulletProof cooler. A clogged stock EGR/oil cooler can blow gaskets too

100% correct

Also if you have the tools and knowledge (pretty basic knowledge) you can do it yourself and save about $3000

 

I forgot to mention I have "HEARD" that the black onyx gaskets have been updated... however, I've not seen any proof and have not heard of anyone running them.

I know cometic has them out now for 6.0's, and I believe RCD has their own gaskets now (not sure who manufactures them), and of course GoGo had custom copper gaskets you could get in any thickness.

OEM are proven to work great though.
