FIXING A SUBARU WRX BOOST LEAK!!

[@zerodohc]

We hooked the smoke machine up to my 07 wrx tonight at work and I had smoke coming from that same area. We pulled the intercooler and smoked it as well with no leaks. We can't seem to see any holes in any hoses or anything. The coupler from the throttle body to the intercooler isn't in the best of shape but still no cracks or holes. I put it all back together and plan to hit it again in the morning to see if maybe a clamp wasn't letting something seal all the way.

Very good to know man, thanks for explaining everything to people who dont know as much as you, I appreciate it thanks

[@dnaautomotive2153]

A common leak is also at the Y pipe in back of the inter cooler.

[@JoseSanchez-wh1zb]

True I had the problem

[@the_privateer1477]

just blew my y pipe out at gridlife lololol

03 wrx owner here, thank you!!!!

[@BaldwinBay]

You just gave me a Better Attitude Boost. Los Angeles can get me down at times. Thanks for the Boost! Another interesting video...

[@SDSBBQs]

That is a pretty cool tool. Thanks for the MAF explanation. Sidebar: I asked about the milled cube a while back I wanted to make sure it didn't get lost in the mail.

[@MorFabIndustries]

Funny thing. I thought I shipped it with a bunch of other stuff until i found it when i cleaned my desk hahah. Ill get it out to you soon!

[@SDSBBQs]

@@MorFabIndustries Thanks Justin

[@cartips5307]

i just bought a 2007 wrx and i think i have a boost leak too. sounds like a high pitch air release on highway speeds but i just thought it was my aftermarket hks bov just like the one in your video. better use your method to check for a leak.

[@ChriswithaCrc]

Great video buddy thank you , I'm having. Issues with my 2006 WRX 2.5 and tomorrow going to look through my pipes again .

[@danielkaesberger7893]

Plastic bag on vacuum side of intake That's now sealed. I always use brake booster vac hose as my smoke test point. Easy peasy.

[@thomsonkev]

Good troubleshooting skills man

[@PREBEE]

Thanks for the info. You made my day

[@franklinmanigat1943]

where we can find the machine test? can that leak cause a check engine flashing at high Rpm? like misfire code after...... thank you

[@joshstenberg8363]

You’re a cool dude thanks for this

[@ksmiles5333]

Subbed washington state . Can you post a link to your smoke machine and the plunger. I have a 2005 outback XT it's throwing the code p0244 and p0301 . I'm wanting to smoke test it but this is my 1st Subaru and want to start buying equipment. Oh, Is it one unit or is it a compressor as well as a smoke machine Thanks

Fuuu bro loved the video always love to learn new things in a practical form.keep the good content coming bro.how do I find out the name of some of these tools you use in your work shop.

[@GarrettB92]

"Or what have you." 😅

[@jakeselvius6502]

Question for ya. I’ve got a 2002 WRX with a full TBE (catless). Sometimes I can hit 15lbs and will hold that but sometimes it will go up to 20, back down to 10, up to 15, then back down to 10. It will do that throughout the pull. Is this a boost leak or is it some kind of overboost?

[@MorFabIndustries]

That is most likely due to the exhaust flowing better than stock. The turbo spools faster, jumps to 20psi and the boost controller slams shut dropping to 10 psi and then re regulating to 15 which is the stock setting.

[@jakeselvius6502]

MorFab Industries Thats what I was thinking as well yesterday actually. Thanks for the info! Any ideas on how I can fix this? Do I get a different wastegate? I don’t have a whole lot of knowledge about these cars, I’m new to the scene

[@kblonded]

@@jakeselvius6502 hey man this is probably way too late but in subies you have to tune pre much everytime u add a mod lol. A full TBE (downpipe + catback) is actually a stage 2 tune, you can either get a protune or get a Cobb AP and run the OTS tune or else you’ll blow ur motor running rich becsuse it’s too free flowing for your stock tune

[@andyhamilton8940]

Boost restrictor pill in vacuum t off wastegate may be missing. People change the vacuum lines and it gets tossed.

[@abc_u_hater]

How do you tell the difference between a boost leak and a misfire? My 07 wrx won't hit full boost stalls / studders around 4.5k to 5k... won't hit full boost.

[@huynguye]

My 06 wrx would hit boost sometimes and other times it would studder. Got error code for misfire. Replaced spark plugs and misfire codes went away but engine still studdering. Replaced fuel filter and pump and that did the trick. So my fuel pump was basically dying at 190k miles lol.

[@abc_u_hater]

Oh dang only have 138k origional plugs coils replaced still stalling.

[@abc_u_hater]

Still no cel light or codes on my ap.

[@huynguye]

@@abc_u_hater have you tried cleaning your MAF sensor? It's $10 for the spray cleaner. I actually tried that and then replaced my MAF with a known working one from a buddy to rule out a bad MAF sensor. You could also have a knowledrable shop test fuel pressure to confirm fuel pump is good or not before replacing it.

[@huynguye]

Also, just for reference, my coils are still original lol. 190k and still going.

[@joecam7109]

The owner of this car is the typical Wrx dude that doesn’t know what the hell he’s doing, blows the engine and then blames Subaru…just take a look at that intercooler just all loose, missing a freaking pcv hose and not only that, he’s running a cheap atmospheric blow of valve instead of the stock bpv without changing to speed density first. He must’ve blow the engine by know for sure.
