Boost Leak Testing 201: Using the tool.
This is the second part of the Boost
leak testing series. In this video, several examples of possible leaks you
might find are exhibited, as well as suggested fixes. Hopefully this video
helps turbo cars around the world to be
healthier and more powerful.
CRANKWALKED? 7-bolt teardown 1080HD
Now this is a story all about how
My bearings got flipped-turned upside down
And I'd like to take a minute just sit right there
And tell you how I used to mix and burn my gas and my air.
In RVA suburbs born and raised
On the dragstrip is where I spent most of my days
Chillin out, maxin, relaxing all cool,
'n all shooting some BS outside with my tools
When a couple of guys who were up to no good
Started running races in my neighborhood
I heard one little knock and my rods got scared
And said "You put it in the garage until you figure out where..."
I Begged and pleaded that it not be that way,
But it didn't want to start and run another day.
I kissed it goodbye, because the motor punched its ticket
I got out my camera, said "I might as well kick it."
Crankwalk yo this is bad
Drinking metal shavings from an oil pan.
Is this what the rumor of crankwalk is like?
Hmm this won't be alright
But wait I heard knocking, grinding and all that
Is this the type of failure that should happen to this cool cat?
I don't think so, I'll see when I get there
I hope they're prepared for this video I share.
Well I pulled all the bolts and when I came out
There were chunks in my fluids in the pan and they drained out
I aint all depressed cause I seen this before.
I got my books and my wrench and we'll do it once more.
I sprang into action like lightning disassembled
I whistled while I worked and my hands never trembled
If anything you could say that this bling is rare,
and when I saw what broke I stained my underwear.
I turned off the air compressor 'bout 7 or 8
And I yelled to crankcase "Yo holmes, smell ya later"
I looked at my internals they were finally there
To sit on my workbench and stink up the air.
Audio track by RojoDelChocolate.
Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag
passes, a half dozen Dyno sessions, 4 transmissions,
3 clutches and 10 years of hard all-weather use.
Boost Leak Testing 101: Building the tool.
If your intake isn't sealed up and completely air-tight, then your turbo is working harder to produce fewer
results. This is a tool used to verify the integrity of the intake, and to
find trouble spots that need attention.
When your turbo is busting its fins to
compress air, why not make all that air go where it belongs... with more
fuel... to make more boom.
This version of the tester with clamp-style tire valve stems in the cap is
ideal because after you have the intake charge (from an unregulated
source), the schrader valve allows you to disconnect the air hose you're
charging it (silencing the hiss of it) so you can hear where small pesky
leaks might be hiding. Testers without the clamp valve are a waste of
The parts list is available here:
Boost leaks can cause idle problems,
misfires, backfiires, squeaks, quacks, honks, or even seem like nothing at
all is wrong except your time slip is a second off at the track.
Everywhere one part of anything bolts to another on the intake, it's an
opportunity for Boost leaks. I've
blown Intercoolers apart.
Not the couplers, the end tanks. Ever wondered what PSI the wastegate
actuator's really opening at from standing over it in the engine bay?
Build this tool.
Until you've verified this on your equipment, you have no idea.... Every
car I've ever tested has Boost-leaked out the Yen-Yang.
Finding Engine Vacuum Leaks With A Cigar
Scotty Kilmer, mechanic for the last 46 years, shows how you can find
engine vacuum leaks in your vehicle using cigar smoke. It really works as
well as a thousand dollar smoke machine. And, If you like my car help, be

Audi TT boost leak testing
Looking for Boost leaks on Audi TT
1.8T 225, APX engine
An empty tin with compressor hose attached is blowing air in to the TIP
hose to fill the system (no more than 20 psi) then listening for leaks.
Keep the oil cap off and clamp the pcv hose shown in the vid. pcv hose
leaks shown are very common on older TT's
How To Make A Boost Leak Tester
I figured with the last video there needed more to be done. I hope this
helps to find those pesky leaks you cant always see.
Boost Leak Testing 202: Hair Spray 1080HD
Why do I know about this?
I'm tired of being the one knowing all the weird crap. If everyone knows
it, it won't be weird anymore. It will be commonplace. By the time I'm
done sealing up all of my own Boost
leaks, all of you will also be experts as well. I'm sure most of you would
teach me something, too... but you subscribed, so here it comes...
something I learned in my travels...
Also, thanks Ilya M. I've only heard about it twice in my life. It worked
great for the one time I've ever needed it, and I'm a huge fan.

If you are buying a turbo to replace a
worn or broken one it is recommended to investigate the reason for the
original fault and rectify before fitting the new turbo, often problems are from oil starvation and
as such a new oil feed pipe is often recommended Or if a turbo blows seals at high pressure it can often
fill the Exhaust with oil and or
water, blocking the catalytic converter This is just a few of the main
problems from a worn out turbo, for this
reason we do recommend the replacement be fitted by a turbo specialist!

High-speed turbo balancing machine turbo Technics introduced the VSR Mk3
"Core" balancing machine in 1999, following 15 years production of the
previous Mk2 machine. Within months, its clever design and many unique
features became the talking point of the turbocharger industry. Following worldwide
acclaim, and the only VSR (Vibration Sorting Rig) to meet full factory
approval by GARRETT, KKK (3K Borg Warner) and IHI, the machine soon became
regarded as the accepted "Industry standard" for all turbocharger repair businesses and aftermarket
re-manufacturers. For full details of our current range of balancing
