I've made my own
snorkel and I've sealed it up with silicon where it goes into the air cleaner. Question. At idle, I thought I should be able to stall the motor by putting my hand on top of the
snorkel pipe. It nearly stalls then seems to get a bit of air from somewhere to keep it going a bit longer. Do I still have a sealing problem or is the motor getting air via the engine breather that's between the air cleaner and the turbo?. It's a current model Navara. Rus.

Hey Rus, havent heard of silicon going hard before,but you are on the right track the engine will get enough air thru the breather to idle.
cheers tony.

Thanks guys. I only sealed it two days ago and the silicon would not have cracked. Tomorrow I'll clamp the engine breather with vice grips and try again. On second thoughts I'll do it at half time in the footy and post the results in about half an hour. Rus.

Well, I clamped off the engine breather tube and I could very nearly stall the motor. Some air was getting through the air cleaner clip on lid but I figure that is good enough, as my hand was at risk of having a 3" circle cut out of it. Don't try this at home. I think I'm satisfied now. Rus.

Another method for testing for air leaks!
Using WD40 or similar, like a cold start spray.
Spray it around the area you believe is leaking.
If after a short burst of spray, the engine increases idle speed, then you have a leak.
This helps to locate an 'area', whereby you can have a more detailed look at rather than a specific spot.

Russel
The best and safest way to test the air intake system is to use your home/workshop air compressor system
using duct tape or alike cover the inlet tube
Tape in air nozzle, reduce air pressure just above air leaks and then use soapy
water to check for air leaks at all joints before and after the air cleaner
Be cearfull not to over pressurise the system as it will scar the $hit out of you when a hose blows off

Have never tried it with wd40 but it certainly works with aero start for finding any air intake leaks on vacum hoses, inlet manifols ect
Cheers
