Oklahoma Joe Longhorn Smoker Mods

Mod 1 : Adding Lock gauges. 

Smoke leakages are common in Oklahoma Joe Longhorn. One of the reasons is the cooking chamber lids not closing properly. 

For me in order to make it hold tightly and not leak through the cooking lids, I used lava locks and installed it on the chamber doors. 

Some people prefer to place it much lower than mine. For me it worked best when I placed it on the upper side. 

However you need to know that this can come in between while opening the firebox lids. Its purely your choice on where you want to place.

Mod 2: Adding Thermometers

Whenever you purchase Oklahoma Joe Longhorn you will get two slots for the thermometer. I wanted to have this done fully . 

Therefore I got new thermometers and installed them. 

What I found is that my two sides have a difference of 10-15 degrees in temperature.

However, I prefer to keep it this way . I like to have one side hotter than the other. It is handy for different dishes at a time.

Mod 3: Using Water Pan

This is highly recommended. I place the water pan under the grates. It doesn’t take up much space . And it is very helpful to manage the temperatures. 

See mine.

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

Also known as the Oklahoma Joe Longhorn baffle plate modification.

This is one of the most valuable modifications so far for me. I highly recommend it .

Using tuning plates helps to even out the smoke in the cooking chamber . It also helps in maintaining the temperature inside the cooking chamber.
In my case I simply bought one as I didn’t want to go through the hassle of making it myself. 

Just got one online and installed it. Either you can fix it through screws or leave it as temporary . 

In my case I screwed it well and attached it. It is really not hard to unscrew it for cleaning.

Mod 5: Remove the Spot Welds and the Brackets

If you see inside the cooking chamber you will see some tiny spot welds under where the baffle plate would sit. Also the brackets . These are for reverse flow models only.

I didn’t require those, So I removed it with the help of an air hammer. 

I really wanted to have the tuning system, therefore I had to remove these welds in order to place my tuning plates properly . 

Mod 6: Seal the Firebox (Oklahoma Joe Firebox Upgrade)

It is a good idea to sealt the firebox with silicon. In Fact I used silicone to seal almost every place where smoke leakages were evident to me while cooking.

If you are tired of your smoke leakage problem then this modification is a must. 

Tips : 

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

Mod 7: Adding ports for probes.

It is very annoying to see the leakages when you want to insert the temperature probe through the lid.
I drilled a hole to insert my probe directly. This is quite handy as I don’t need to put my probe through the lid. 

You can attach a rubber port to it to prevent leakages and easy insertion of the temperature probes
