10,000 miles on my Black Onyx heagaskets! So far, so good.

Figured I'd start a thread on the status of my headgaskets. With everyone saying the black onyx/victor reinze gaskets are trash, I decided to start this thread to keep everyone up to date on mine. I installed them about 2 months ago, and my truck hasn't stopped running since. Nearly every mile has been hard towing (one occasion had me crossing the scales at nearly 26,000lbs), and she's been doing well. No sign of coolant loss or other signs of failure. I just got back from a 2500mile round trip towing another SD dually with an additional 5klbs of spare parts, and she's running like a top still! Updates to come periodically. I rack up mileage VERY quickly this time of year, so this is going to be an accelerated progress thread.

NOTE: Towing is done with my ID Aggressive tow tune, daily driving is done with my ID extreme street tune.

Sure do. Just made a trip to MO to scoop up another superduty. 2500 mile round trip. Nothing like a long tow to help the old girl stretch her legs!

299,213 miles on her. 300k is fast approaching.

Well that's good. have read some of the horror stories popping up lately as well. Just wonder how many are machine shop and/or repair shop errors? Surely after a few years of people using them, they can't just mysteriously start laying an egg. Well, unless a bad batch of them was made or something along those lines.

I am approaching 15000 with mine. So far so good here also.

yea man thats awsome and people say they have never seen a 6.0 with 300,000 miles... here is one for them

Good to hear a success story. Some of the guys on here are sure they are no good. I have about 200 miles on my Sinister B/O V/R gaskets.

Good deal-seems like all we hear about are the failures. I'd love to hear from some more people who haven't had issues-get a better perspective on the issue.

As for the possibility of machine shop/installer error, I wouldn't rule anything out. The OEM gaskets just look like they are more forgiving. I have a theory on the failures-since the OEM gaskets only seal around the perimeter, they allow the block to corrode from coolant where there is no sealant-I believe since the BO gaskets DO seal around all the passages, the corrosion and pitting keeps them from seating properly as there are high and low spots. I was surgically clean when doing mine-several cans of carb cleaner, hours of sanding and polishing the

I have one that made it to 430k before an injector failure caused the #8 piston to meltdown.

Funny part is, the cylinder walls are still in great shape. The crosshatch is still visible!

That's awesome!

What caused the injector to finally fail? Was it giving any signs or symptoms before it went out, or did the tip just fall off?
