Watch This BEFORE You Walnut Blast Your Valves - Turbo Direct Injection Probs - Pete Bruschi Racing

In this series, I measure the power losses caused by air-oil contamination and intake valve carbon deposits. There are many videos documenting the benefits of walnut blasting, the preferred method of cleaning. Though I could not find any that verify horsepower gains on a dyno. The engineer in me had to know!
All engines are prone to some form of carbon buildup, but Turbocharged Direct Injection Engines are particularly vulnerable. Because all of the fuel is sprayed DIRECTly into the cylinders, there is no way to keep the intake valves clean (like Port Injection does). The mandatory emissions-compliance PCV and EGR systems recirculate fuel and oil vapors back through the intake, which inevitably burn onto the hot intake valves, creating a thick carbon coating. The extra crankcase pressure from the turbo puts extra oil and strain on these systems.
As this carbon builds up, it can start to interfere with the flow of the air into the cylinder. This could cause misfires, loss of power and fuel economy. Left unchecked, this carbon can even cause catastrophic damage.
After 4 years of beating, I could tell my 2.3L Ford EcoBoost was not hurt, but definitely not running at its peak. It exhibited rough idle and misfires, though nothing severe enough to trigger a Check Engine Light. While I wasn't 100% sure of the cause, I suspected that at over 100,000 miles, I could have carbon deposits on my valves.
It turned out that this was well worth the investigation.

In Part 1, I performed a baseline dyno measurement on my 2015 Ford Mustang Ecoboost, after reaching 100,000 miles (90k added by me daily driving) and over 150 days performance driving on closed courses in 4 years:

In Part 2 (this video), I perform the walnut blasting process, thoroughly documenting my process and all pitfalls that I discovered. The job was performed over an entire weekend, for less than $200.

Not sure if I will have a car I will need to do this on, but I give you props for tackling it

[@user-to2ii5ev4p]

Great Job! Installing catch cans will help minimize the oil going threw the intake track.

[@pete_bruschi_racing]

Already done. Working on the follow-up video!

[@user-to2ii5ev4p]

@@pete_bruschi_racing Good Deal

[@RANCHER_LTB]

Great work! Looks well worth the effort!

Hey man great video real informative and really could steer anyone who has never done this before in the right direction props to you man

[@kaelanhinz9020]

Nice video Peter!

[@BasketballAve]

Really great video well put together and very humorous…

[@B_RON_CO]

Nice edit 👍

[@bobblueton]

New here, the memes are killer. Great job bud.

[@aaroncetina1783]

Liked and subscribed, useful info and I like the added humor. You should do a vid describing any mods you've done, what you've liked and disliked with them.

[@pete_bruschi_racing]

Thanks, will do! I have several ideas for mod videos. I have things that have been on the car 2-3 years that I think it's time to give them a fair review. Unfortunately videos take 10's of hours to make and I've got a lot of stuff on my plate! But I hope to get to them eventually.

[@MrDavidmd43]

Good shit to know! Thanks. Also like the addons. I wanted to see the shop vac shoot flames!

[@pete_bruschi_racing]

Lol that poor old vac is older than me. Still sucks!

[@Jus275]

Just found this video and it's super interesting, thanks for all of the great information. Also you're hilarious I'm laughing my ass off.

[@driverjamescopeland]

In 1970, Buick ran into issues with carbon buildup causing pre-det in the of the X-SF code 455 (Riviera, Wildcat, Electra 225 engine). Carbon deposits in the chambers were causing the factory 10:1 chambers volumes to shrink, raising compression to well over 11:1. Buick sent word (a kind of not-service-bulletin) to service centers, advising them to walnut blast the chambers and change the oil. Many had their worries about trashing rings... but I have never heard of one failing from the treatment. In other words... no worries, if it gets into the cylinders. Blow them out, change the oil, and carry on.

[@pete_bruschi_racing]

Cool story! Though best to not get it in there, especially on turbocharged applications.

[@namen0tf0undnoname87]

Made that look way easy!

I wish it was 😅

[@roadlesstraveledd]

i think you'd be the only one on the internet with actual real results of walnut blasting before/after. and I'm dying to know haha. get that video out!

When do we get to know the dyno results? I gotta know! lol

Hey there! Great so far! I will be making a video!

[@tommykane4621]

Awesome! Insightful. 7;^>....

[@princesssolace4337]

Honestly, it wud be much easier to add a port injection on a new aftermarket intake manifold. At least my fueling is covered incase I wanna add more boost.

[@pete_bruschi_racing]

Good point, though I don't think that's legal in some of the classes that I want to race in.

[@princesssolace4337]

@@pete_bruschi_racing Just bypass the fuel line for the racing event. Job done. I fix a port injection on my Gen2 Speed3 bcoz I hate doing walnut/media blast.

[@pete_bruschi_racing]

@@princesssolace4337 unfortunately, it doesn't work that way. You can't have illegal parts installed whether they are functional or not. At National Tours where everyone has to open their hoods and trunks in impound for scrutiny, it's not worth the trouble.

[@princesssolace4337]

@@pete_bruschi_racing You'll figure sumthin' out. Those carbon deposit add unwanted weight on the valves when it gets hardened and its gonna shorten your stock valve springs life.

[@theTanees]

do you need to readjust the valves when you are done for timing?

[@pete_bruschi_racing]

Timing is entirely controlled by the cams and the ECU. No valve adjustment required. Great question though! Did you know that we have variable valve timing?

[@theTanees]

​@@pete_bruschi_racing Thank you! wasnt sure if cranking manually mattered as to what position to leave it in once done. I'm doing this on a 2016 Hyundai Accent but stopped from uncertainty. I really appreciate the info. I chaged my vvt on my lexus 2 yrs ago but didn't realize if firing order needed to be followed at TDC. Geez derpy doo on me.

[@pete_bruschi_racing]

The crank angle sensor will figure out where it's all at. Be careful and best of luck!

Yes, follow-up in the works. Race season hit me like 🧱💥😵‍💫 Hard to find the time to edit! Thank you for your patience!

Those clips are so damn simple. All you do is push the hose on as far as possible and then just push the clip in to release

I caught hell with the same blaster 😒

[@pete_bruschi_racing]

Hmm yeah no issues here but Harbor Freight can be a crapshoot

[@BrandonSalas-us8mm]

Lug the engine?

[@pete_bruschi_racing]

Don't hang out in the low RPMs, especially don't build long sustained boost. On my EcoBoost cruising down the highway I keep it over 2000 RPM and below 0 psi boost. If I need to climb a hill or pass somebody I always downshift. That puts the engine in the right RPM range so it doesn't have to work so hard.
