- In this one we track down some pesky unmetered air that was causing this WRX to be a bear to tune. We found a few things and took care of them with the help of our handy smoke machine.

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
You just gave me a Better Attitude Boost. Los Angeles can get me down at times. Thanks for the Boost! Another interesting video...
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.
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!
@@MorFabIndustries Thanks Justin
A common leak is also at the Y pipe in back of the inter cooler.
True I had the problem
just blew my y pipe out at gridlife lololol
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.
03 wrx owner here, thank you!!!!
Great video buddy thank you , I'm having. Issues with my 2006 WRX 2.5 and tomorrow going to look through my pipes again .
Good troubleshooting skills man
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.
Thanks for the info. You made my day
You’re a cool dude thanks for this
Super helpful. Thanks man.👍
If you dont have a smoke machine just use your vape since all subie owners vape anyways 😂 lmao jk great video i hope this is my problem and nothing more serious.
I use sage to ward off the bad spirits from the inside out.
You joke, but this works 😂
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.
Awesome bro…

Is that HKS set to recirc? Or are you tuned via SD? Great information, thank you sir
where we can find the machine test? can that leak cause a check engine flashing at high Rpm? like misfire code after...... thank you
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
great content
What's the plugging tool called?
I need to know this too!
@@keithfeiden1133 found out mine was just a cracked downpipe right at the turbo but I found the tool anyway

@@MorFabIndustries 🤘🔥 definitely nt a problem
"Or what have you." 😅
2017 subaru wrx
Do u have to blank off anything?
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?
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.
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
@@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
Boost restrictor pill in vacuum t off wastegate may be missing. People change the vacuum lines and it gets tossed.
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.
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.
Oh dang only have 138k origional plugs coils replaced still stalling.
Still no cel light or codes on my ap.
@@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.
Also, just for reference, my coils are still original lol. 190k and still going.
He's missing driver send tmic bracket
will a vacuum leak make my car idle rough?
Where you at
Where are you located at?
Link to the plug/ bulb tool ?

MorFab Industries thank you Sir!
Throttle cable routing incorrect.
What is the tool name that you put in the air intake
It's a matco smoke tester
@@MorFabIndustries he means the pump thing. I need to know that too
Kept trying to blow the smoke away while listening to what ya was explaining ^_^ ffs.
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.
"importANT" not "importent"
I just want to know, how a real mechanic had such manicured fingernails 🤣🤣🤣. Stop, pause the video and see the big guy has perfect nails. Come on RUclips, Really
Never even made it to the video too many freaking advertisements one about some dude putting on makeup and some other dude blowing him it's too much
Aren't these all targeted ads...?
