I made a boost leak tester as posted on this forum. It definately works and I found leaks at the connection of my UICP. The tester connects to the turbo inlet and requires removal of a number of hoses and blocking off a number of hoses (breather (?) hose).

Anyway, my question is why is there not a easier way to do this? If there were a bung on the intercooler piping (or somewhere else convenient), could someone design a valve stem that would screw into the bung and could be pressurized? This would make a pressure test very easy (could drive up to a pressurized air source at a gas station and test/tighten).

Any thoughts?

Thanks.

That would be a good idea , but you still would need to remove the MAF , intake pipe , bov retrun pipe and then block off the turbo inlet to seal up the IC system...

 

Oh yeah. I forgot about the intake.

Thanks.

As above, the tester posted on this site works well.

Thanks.

 

I still like the idea of using an air fitting so you could use the tire inflation tool attached to your comnpressor to pressurize the system.


Isnt there a colored liquid that you could apply at all the joints downstream of the turbo outlet (pressurized side) and then just drive the car+build boost, then look at the liquid for signs of a leak?

Of course you would want to apply the liquid on the outside...dont want it going into the engine.

 

What if the pvc plug with the valve stem plugged in where the stock air box comes off. Then everything else could stay in place (BOV niple, breather (?) hose, etc.). Basically the same design as before, just a little further upstream.

Would this work?

Thanks.

I a like to use soapy water (blows bubbles) or smoke a cigarette...this usually reveals the leaks.

 

how can it blow bubbles if its in vaccum?

 

+1 soapy water in spray bottle

 

It's not going to build boost unless you drive it. How do you plan to look for the bubbles or cigarette smoke?

 

LOL, More importantly, how can it be a boost leak if in vaccum?

 

OMG people. Plug up the intake and hook your air compressor to it. This creates positive pressure (i.e. boost).

 

your not driving the car while doing this
its disconnected and using compressed air to pressure your system so when you spray the soap and you see bubbles you have a leak
