air leak check?

[ktmhans]

So justin at bb says i have an air leak somewhere. Truck has 122k on a 5.3.
I did the intake gaskets 6 months ago. I changed some other emmisions solinoid a while ago on the intake.
Besides making sure things are tight,. What else can i do? Spray carb clean around?
Thanks

Ok so i. Had some time yesterday to poke around. The only thing i could find was the rubber gasket on the map sensor on the top rear of the intake. The very bottom of it has a tear. Dam sensors are $47. Thats an expensive little piece of rubber if thats even whats doing it.
I dont think carb cleaner works to use as a test, starting fluid might but tharts a little rough on the motor.

many use an unlit propane torch, less mess and less chance of a flash or explosion.

Interesting.

No problem, you should be good. Obviously, don't leave the torch on for a long time creating a big cloud in your garage. My buddies that work at various local dealerships all use this method, cheap and easy.

Good luck!
