"Black Diamond Gaskets"

[toren302]

Well I thought I would start this thread to see if anybody has tried these yet. If not...well ill be the first. I know only OE is the way to go. Thats what we install on every customer rig. My truck is going to be an experment. Fist some history. It was around 108k that I started puking. I worked for a tire shop then and they let me use the twin post to lift the cab but did not want the rack tied up for long. I did not pressure test or deck the heads back then needed the job done quickly. I knew it was a risk back then. So here I am at 124k and a year and a half later and NO heat. When you pull the cap off the coolant bottle it looks like a hot tub bubbling away. I can get 1800f out of her with the looney tune I have when wide open. Pretty sure I have one or both cracked heads. When I did the gaskets and studs the first time I noticed CYL 1 has a vertical notch all the way down the cylinder wall. I bought this truck at 85k. The compression is not low on the cylinder. So this time I am going to try these gaskets and see how long she lasts. I know a long block is in the future just not in the cards right now. I really want heat so I have a new set of heads with harden seats, machined and these "Diamond" gaskets. We will see how long they last. Heres hoping the block goes before the gaskets.

Why would you want to waste time and money? Go with what is proven. OEM or nothing!

Someone has to try them. I am not worried about wasting time I love working on the motors, and trucks. It cheaper for a set of black diamond gaskets then factory. I need a motor to fix her properly. Those are the only excuses I can come up with right now.

Who are making these gaskets? I have a feeling these are just Black Onyx gaskets with a different name. The Black Onyx gaskets have been proven to flat out suck. It doesn't matter how cheap they are now, chances are you will be replacing them with OEM gaskets, so you will paying for parts twice.

My plan is that when either the gasktes go or the motor gives out to replace it with everything I want for one final time, and build. But that is going to take about 8k. I dont have that right now and need heat back in the truck. The black onyx gaskets are crap. The Black diamond gaskets area a MLS with a black coating in the same places as the OE blue stuff.

Just going to try them mostly want to see and feel them. I will get them and post pics with them next to the ford OE gaskets. I am in no way saying these are the best thing out there Like I said OE is all we put on customers vehicles. We wont warranty the head gasket repair if they ask for black onyx. Most go for the OE when we tell them that. My motor is on it last leg.

They are the same gaskets as the black onyx, waste of your time and $$$. Double check with mkm but doubt they'll answer , wouldn't respond to my emails about the black onyx gaskets blowing in 10k miles ( coolant passages blown clear through)

Those are the gaskets the shop put in mine the first time... Only lasted 5k and they were blown to hell the shop told me they were blown worse then any gasket they have ever seen and they build pulling trucks and alot more high hp rigs then mine.

First it was PMM who said they were "Their" gaskets. Now Sinister has them?? Anyone else smell fish??
