Back when I had my 92 Colt hatch with a self built 4G63t engine, I made a boost leak tester out of a spray paint (rattle can) cap and a 1/4 air chuck and did exactly what you guys did here. When you're broke, you learn how to get in touch with your inner McGuyver and make shit work. I set the regulator on my small compressor to 15 lbs and plugged in the air line and found that my vacuum tees were the problem. Man do I miss owning a turbo car. Thanks guys!

Actually, this boost leak tester is not that good. Best way to do this is to pressurzie the turbo intake. That will allow you to test the turbo too. Also, you can leave the intake charge pipes on. Then you listen for leaks. You will hear air escaping into the engine, but my method will allow you to test the entire system, including Throttlebody, gaskets, vacuum hoses etc.

This is hilariously full circle. 10 years ago I bought my first Subaru. Was looking for mod videos and found you guys. Recently brought the Subaru out of storage to get to work bringing it back to what it was, this video came up to show me how to check for boost leaks on the cheap. You guys are making auto community history and have been since 08!

Even though i live in the USA, most of the cars MCM works on aren't available to me, and i drive a naturally aspirated infiniti g35, i love watching every single video these guys make. Who cares if most of it doesn't apply to me, these guys make everything fun.

black200sxser You kidding? Top Gear is epic shit, I do however think these guys should do 5 minute quick tip or whatever stuff WHILE Top Gear is on, No offense but even mighty mods needs to realize that Top Gear is just good viewing fun, nothing can replace.

what sucks is I get most leaks from the T boltstyle clamps all the time and the cheap hose clamps don't leak go figure, A note when you put the couplers back on spray them with hair spray this will keep them from ever blowing off in the future

their little home made system would be superior to the bought one if it had a pressure gauge bolted into it and a ball valve between the plug and the air fitting. given those parts can be found cheap enough.

16GDSM Top Gear UK is amazing. Black200sxser is referring to Top Gear Australia (totally different program sharing the same format) which has not been received as well as networks had hoped in Australia.

sdutango Generally no. this pipe would be pressurized under normal situations. All your doing is adding boost without the extra noise of the engine running. This lets you hear where leaks are.

If your having a hard time finding the leak, use a spray bottle with soapy water, it will make bubbles were the pressure is escaping. Saved me allot of time plugging leaks on my 92 talon
