"here's something uh perfect and perfectly dangerous that i found here" lmao i have a boost leak somewhere on my car and this video helped alot and it was funny, thanks for the video

[@pigeonsil240sx]

I'm confused why you wouldn't want to pressurize the entire intake manifold instead of blocking off at the throttle? i just found a massive boost leak at injector o ring that would not had been found using this method, it was a tricky leak because it only appeared once about 3 psi was induced. by only pressurizing the intercooler assembly you can miss many many leaks,the system was designed for boost so its not like its gonna hurt anything right

100%

Thank you for the video. It was easy to understand and very detailed. Much appreciated.

Two words. Duct tape. Greatest invention ever

Edit description add there B5.5 1.8T VW passat to make sure who has 1.8T engine they can reach to this video. Overall great job. Thank you

[@anthonyboni5884]

you got yourself a subscription. awesome awesome stuff

[@deejayimm]

Why can't you just use a pull through valve stem, then if you use a tire chuck to fill it you have a pressure gauge right there.

[@danpiontek9839]

Thanks for the video. I put together a twin turbo sbc but it is not making boost. hopefully this vid will help me pin point the issue and I can make some horsepower. Thanks again

[@BigSteve_Gaming187]

Thank You. Got my hands on a 04 VW 1.8t 4motion wagon. Wasn't well taken care of so it's a definite need to check.

[@moekhalilfishing]

This is very very helpful can you help me with my VW 2004 Passat 1.8t , have 0442, 0456, 0411, 0299... I tried all solutions with no luck !

[@joker2712005]

Great video homie. I heard my oil pop pop pop pop pop but no leaking. I didn't hear that oil sound on yours, is that a bad thing on mines? Thanks for ur advice and awesome vids!!!

[@acruz6112]

good stuff man helped me out alot thank you.

[@IRDG96]

Great video, thanks for making this! Do you have any information on replacing a whole turbo? Or for a Passat, upgrading to a k04?

[@NimaSomeh]

thnx so much for teaching us , god bless you and your family. I have a question : can I do this with an emergency tire compressor , you know the one that uses 12v cigarette lighter plug ? thnx

[@myRatchets]

you can do this with any kind of compressor or even a manual air pump. Just have to find the right fittings..also VERY IMPORTANT to be able to accurately regulate the air going in and stay within the threshold. If you put too much compressed air in, you will damage something and cause a boost leak where there wasnt any before. Also your adapters will come flying at you. GL

[@stewartrivers2730]

Thank you .

[@BigSteve_Gaming187]

I've seen a guy use soup cans to block those off. I'll check that soon as I get my fogging machine setup 4 the job.

I used a pineapple can lol

Looking to easily test where boost leak is on my audi b5 a4 and first video is the exact same 1.8t same colour

[@kevincrowley5064]

Nice video, thanks.

[@MrBow54]

You can also make a cold air intake with PVC pipes Just make sure all your sensors are hooked up That's for us really cheapies

[@myRatchets]

haha interesting.

[@RealDigitalP]

I know this is an old video, but does anyone know what the small hose that was clamped with the pliers is called? I have a 1.8t AWT Passat and I don't seem to have it coming out of the tube from the air filter box (the tube looks a bit different).

[@googlekonto8275]

RealDigitalP I think its called a Engine breather hose

[@genuinestyle4872]

nice video

[@mariosevilla4886]

What’s the size on the pvc hose caps?

[@rpbpendeavors9831]

Thanks man

[@justinmckee2256]

What’s the best way to regulate the PSI? I have a standard pancake compressor available to me. Is there a regulator I can buy? I assume so

[@stevenmcfarland3742]

I picked up a regulator kit at a local Autozone that fit the end of my compressor hose.

[@jesusjessereyes6633]

Snuggley!.. lol🤙

[@sebastianaponte9009]

The small hoses close to the turbo that you clamped with the pliers . Was 1 of those a diverter value hose ?

[@unfknknown9678]

Sebastian Aponte no

I dont have these small hoses that he clamped with the pilers on my 1.8t audi 2001 :/

what about the injectors seals

[@IMARBAN]

I have a 2012 chevrolet cruze 1.4 ecotec. that sends me P0299, It comes on and it was away... so, I don't know what really it's happening‼😰‼

[@Chris-lz7sx]

Hi! I have been following you for quite some time now and I love your videos. Keep them coming. I have a 2005 Audi 1.8T and I just recently upgraded to a few performance parts and I re-allocated the N75 valve away from near the turbo where it was originally located to the firewall passenger side. Will this affect boosting issues because of the greater distance it now has away from the turbo? Thank you in advance.

[@c12_pra72]

You can just delete the n75, they are sometime faulty causing boost psi to spike and that can cause some damage

[@Chris-lz7sx]

@@c12_pra72 Then what is the replacement for the N75?

[@c12_pra72]

@@Chris-lz7sx there is no replacement, you delete the n75 and just cap it off as it’s not necessary

[@Chris-lz7sx]

@@c12_pra72 the n75 valve is a boost control valve how can that just be removed and not replaced.

[@dubvalver]

you cant just remove it. you'll only run off the wastegate setting if you do (4psi?). you would need to run a manual boost controller instead if you removed n75. but dont do that. personally i would keep the n75 close to the turbo. i moved my dump valve close to the throttle body for the same reason. (i have a race ecu and run 100% atmospheric dump valve though)

[@krogtv9411]

nice :)

[@corry7040]

why not use your paint cansmoke machine?

[@theautodidacticman_]

Spray soapy water and look for the bubbles

What are symptoms of a boost leak?

[@nickpsp2]

Lack of power Can't hear the turbo spooling up lumpy idle

[@joker2712005]

Nick Marsden OK perfect.. Thank you for ur response and ur vids :)

[@istvanpista7895]

Wouldn't it be safer and better to just use a smoke machine?

[@myousic4564]

Some leaks appears only with certain pressure - there was an example in the video. No way to find it with smoke without pressure.
