Hi everyone,

Two things need to be noted from the photos. One is that the heat tabs are melted on one of the pictures, so we see that the engine got excessively hot. Hot enough to melt the heat tab, as seen in the photo that we're showing below.

Secondly, in this screenshot I'm posting, you, yourself, Mr. Austin, admitted that the engine ran hot, as seen in the screenshot of the text message you sent us.

But obviously, when a cylinder head gets excessively hot and melts the heat tab, it's going to cause distortion, or warpage, which will cause a head gasket to fail. 
That's the reason why the warranty was denied. It was never said that a 40-horsepower tune would cause that. We did, however, mention that there was concern for injection timing. You can clearly see that the heat tab is melted, and per our warranty, and ANY other manufacturer, by the way, will tell you the exact same thing. 
If the heat tabs are melted, then the engine has been run excessively hot. I know you initially said you did not see any high temps when you were driving the truck. Well, if there's no coolant in the cylinder head, or if there's no coolant around the temperature sensor because it's pushed that coolant out, you won't see the truck run hot because there's no way no conduit for it to convey the temperature back to the ECM.
As for your cylinder heads, we EXTENSIVELY examined/inspected your heads, checking the spots marked as potential cracks and checking anything else that could have been wrong with them. We vacuum tested them. We pressure tested them. They passed both the vacuum test and the pressure test. Neither of the heads were cracked. (Which I think is evident since you have since sold the truck to someone else and it's running strong.) We had our engineers run a straight edge across the heads in both directions, and they were not warped at all. We even had our team members take pictures and videos every step of the way so you could see exactly what they were seeing. They uploaded them all to a Google Drive folder (which I am happy to provide the link for here if requested), which was shared with you. Including videos of the vacuum test and pressure test, as well as close-up pictures of the spots that were marked as potential cracks. And we still agreed to go ahead and upgrade your heads for you. We cleaned them up and o-ringed them to give you added reliability/durability going forward.

I know you commented about us not o-ringing your heads in the first place, which was because you purchased our Daily Driver engine, not the Workhorse that includes o-ringed cylinder heads. Had you purchased a Workhorse, then it would have absolutely had o-ringed heads right out of the gate.

I'm not sure why you feel like you never were able to reach anybody, because we were in constant communication with you via email/phone calls the entire time your helpdesk ticket was open. You spoke on the phone to a team member and even to the owner, Cass Choate, multiple times, on several occasions. He even provided you with his personal cell phone number so you could always get in touch with him in case you needed anything. I hate that you feel like you had a negative experience with Choate Engineering Performance, but I'm not sure what more we could have done to please you, Mr. Austin. We hope this helps clear things up for anybody who had any concerns regarding this situation, and we wish you nothing but the best.
While I got you here Cass, I'd still like to know how those studs were loose from the factory. Again, the mechanic that installed the motor found it, not me. Why would he lie about that?

It was loose on the same side as the blown head gasket that you refused to warranty.

I'll wait for your response.

Hi Johnnie,

This is a representative at Choate Performance, not Cass himself. I'm sorry you feel I'm coming back with a smart-aleck response, because that's not the case at all. I'm just giving you the facts. As for the machine shop, well, this is also the same machine shop that said we needed to magnaflux the aluminum heads on your 6.6L LML Duramax.. which is something you cannot do on aluminum heads. Magnaflux only works on ferromagnetic metals, such as iron and steel, which can be magnetized.

Unfortunately, in this business, whether it's the engine manufacturer's fault or not, they will always be blamed for whatever issues a customer encounters, which means even if it's so clearly not a warrantable issue, the recourse they take is leaving bad reviews. And I understand, no one wants to be told the issue is not covered under warranty. It's a sucky situation. I'm not saying CHOATE has never made a mistake, but when it is on us, we honor our warranty.

As for the truck, I'm sorry you have no faith in your truck or our diagnosis of what was wrong with it. Fortunately, you had the head gasket replacement done and sold the truck, which has been on the road and running ever since. The new owner called to transfer over the warranty, so again, we say- we hate that you feel like you had a negative experience with Choate Engineering Performance, but I'm not sure what more we could have done to please you, Mr. Austin. We hope this helps clear things up for anybody who had any concerns regarding this situation, and we still wish you nothing but the best.

Why did your "Better than OEM" engine have loose head studs from the Choate factory and blow a head gasket at 9000 miles?

I've asked that multiple times and still no answer. The mechanics told Cass on a conference call the head studs were finger tight on the blown head. Choate assembled the heads and Cass says he has proof they torqued the studs, but I haven't seen it. Don't give me a generic video either. The root cause of this whole fiasco is the heads were loose. Choate assembled them. Why were they loose? That cost me almost $6000 grand when you said 'no fault found' on heads you sold with a warranty.

Also, the machine shop did not say to magnaflux the heads. Go back to the email on March 17th and re-read it. I'll be happy to post screenshots if I need to. I misspoke, then after Cass's smart-alec response, corrected myself. Cass knows this.

As for the truck still running today, of course it is. I paid $6000 to have it fixed correctly and then sold it. It's nothing Choate did, believe me. I won't pass a lemon off and then expect to sleep at night. The truck ran for me for 9000 miles3, until it blew a head gasket due to loose studs. Don't even try to take any credit when it's not due.

Now, you want facts? Those are the facts.

So I ask again in case you missed it the 10th time. Why did your "Better than OEM" engine have loose head studs from the Choate factory and blow a head gasket at 9000 miles? I'll wait.

Update: I got a phone call from a guy looking to purchase my old truck with the Choate engine. He'd gotten my number from the guy I originally sold it to. He told me the engine is now having "excessive blow-by" and he was thinking of contacting Choate about the warranty. I told him to read this thread and then decide if he wanted to waste his time. That said @ChoatePerformance_CSR , your "better than OEM" motor is again having issues. It sounds like selling it was a smart move on my part.
