Oklahoma Joe Longhorn Smoker Mods- Easy and to the point.

Mod 1 : Installing Lock Gauges.

Smoke leakages in the Oklahoma Joe Longhorn are a common issue I’ve noticed. One primary culprit? The cooking chamber lids not sealing correctly.

To combat this, I personally opted for the Lava Lock clamp, installing it directly on the chamber doors. It made a significant difference in ensuring a tight seal.

While some prefer positioning the clamp lower, I found it most effective on the upper side.

However, a word of caution: its placement can sometimes interfere with opening the firebox lids.

Ultimately, the decision on where to place it rests with you, based on your preferences and needs..

Mod 2: Incorporating Additional Thermometers

The Oklahoma Joe Longhorn comes equipped with two slots for thermometers right out of the box. Wanting to maximize this feature, I decided to install new thermometers myself..

To my surprise, I observed a temperature difference of 10-15 degrees between the two sides. But, rather than seeing it as an issue, I’ve come to appreciate this variance. Having one side hotter than the other is quite beneficial for me, especially when I’m cooking different dishes simultaneously.

Mod 3: Incorporating a Water Pan

I can’t recommend this enough. I’ve positioned a water pan right under the grates.

Not only is it space-efficient, but it’s also a game-changer when it comes to temperature management. Take a look at how I’ve set mine up.

Mod 4 : Using Diffuser or Tuning Plates (Oklahoma Joe Longhorn Tuning Plate)

This modification has been a game-changer for me, and I can’t stress its value enough.

Tuning plates play a crucial role in distributing smoke evenly throughout the cooking chamber.

Plus, they’re instrumental in maintaining a consistent temperature..

I opted to purchase one online, sidestepping the DIY route to save time and effort.

Installation choices vary: you can either secure it with screws for a permanent setup or leave it temporary.

In my setup, I firmly screwed it in place. And trust me, when it’s cleaning time, unscrewing it is a breeze..

Mod 5: Eliminating Spot Welds and Brackets

Upon inspecting the inside of the cooking chamber, you might notice tiny spot welds situated beneath where the baffle plate rests, along with some brackets. It’s worth noting that these are specifically for reverse flow models.

For my setup, they weren’t necessary. So, with the aid of an air hammer, I promptly removed them. My goal was to optimize the tuning system, and to ensure my tuning plates sat perfectly, these welds had to go.

Mod 6: Securing the Firebox (Aka the Oklahoma Joe Firebox Upgrade)

Sealing the firebox with silicone is a smart move. In my journey with the Oklahoma Joe, I took it a step further. I applied silicone to virtually every spot where I noticed smoke escaping during my cooking sessions.

If smoke leakage is a persistent issue for you, as it was for me, then this modification is essential.

Tips : 

It is useless to put sealant around the area of the firebox lid closing as it burns off with heat soon.  

Mod 7: Introducing Ports for Probes

There’s nothing more frustrating than witnessing smoke leakages when trying to insert a temperature probe through the lid.

To tackle this, I took the initiative to drill a hole, allowing for direct probe insertion.

This modification has been incredibly convenient, eliminating the need to thread my probe through the lid.

For an added touch, consider attaching a rubber port. It not only prevents leakages but also facilitates smoother insertion of temperature probes.
