Hi BavarianAuto, great Video footage of you at work on the BMW turbo Engine i may not have a turbo engine but i still enjoy watching your video's, thank you.

I scrolled down in the comments and saw about $1100.00. Keep up the great videos.

this so good to meet a best advice about to clean a intake manifold thank you engineer

This video is amazing. Nice job thanks.

Wow! thats a lot of disassembly and work ! After taking apart all that , most likely a vacuum hose will break or something else causing my engine to run worse !

Greeting from Shanghai! Thanks a lot for this high quality video as always. Has been learned a lot from your channel. One question, as I know for N54/N55 engine and all the newer BMW engines, there are small passage holes on each cylinder head intake runners for crankcase ventilation purpose, so is there any risk that the walnut blown into this passage?

Great tutorial!

I'm in the same boat. I have a 2011 35d, and a 328xi. There's a carbon clean procedure that utilizes hydrogen, and does not require opening the manifold, however the locations in the US are few and far between. Walnut my only option as well.

Would running seafoam or another agent into the intake manifold be beneficial in preventing carbon buildup?

wow that interesting , I would like to try one day.

Great video - always wanted to know what was involved with this. Another 10k miles and I'll be tackling this one

which valves need to be open or closed when you go to pressurize the walnut tank? which valves need to be open at the tank in order to shoot out the media when the valve at the handle is open?

To Fredy - We can't reply directly to your comment - The procedure for the diesels is a bit more involved and actually involves multiple port adapters and blasting wands. We have not addressed this as a DIY yet.

hi sir..i have a problem with my mini cooper s 2012. the computer shows to me " low pressure". i changed the high pressure pump and there is no change with the problem. do u think its because of the carbon? maybe i have to clean it?

Do these type of carbon build up cause misfires on a specific cylinder?

So if you reroute the crankcase ventilation tube to atmosphere does this problem go away? 🤔

With the new subaru FA20 engine platform being direct injected there will been a rise in carbon build up problems so I will be purchasing one of your kits but I have a product suggestion you should make a shop vac intake valve adaptor for the FA20 subaru motor for purchase the FA20 motor is used in a lot of subaru's new cars and people are going to start looking towards walnut blasting since DI engines have carbon issues

Hmmm what if the valve is not 100% sealed, you tapped it so the starter just turns a bit but worse case could the car fire with a little walnut? Also how long is this process?

Can the blasting media be reused?

"I would recommend performing a fuel injector flush as this vehicle still has solenoid type fuel injectors. It is something that cleans the injector internally from build up, injector tip and also the back side of the intake valve. It is recommended approx every 100,000km..." this is what the SA at the BMW delaership just told me. I wonder if that "fuel injector flush "is the same than the" Engine Intake Valve Cleaning with Walnut Shell Blasting"....

Is this now available for the E90 335d? M57 engine. (I think it is from looking at your website) I have a 2010d with 90,000 km on that I'm pretty sure has carbon build-up issues. If anyone knows of anywhere in the Toronto area that can do this on a 335d for a reasonable price let me know - Budds in Oakville charge around $1450+tax for doing this and I'm not 100% convinced they have a lot of experience doing this. J&R Auto Electronics in Oakville have experience making ECU program modifications to the EGR that will significantly reduce the problem but they don't actually do the decarbonizing at this time.

Are there any places that do this other than the dealership!? I have 335i and would like to get this done without having to pay 800-1000$ . Thank You.

Short of scraping or blasting, if you run the Liqui-Moly Motor Cleaner before each oil change and run the Liqui-Moly synthetic oil (highly detergent to the carbon and sludge), with 3000 to 5000 mile changes .... over time, the sludge and carbon will clean up quite a bit. See these products in our online store at www.bavauto.com

What are the adverse effects if any, from walnut fragments entering the combustion chamber?

@bavarianautosport

9 жыл бұрын

Very minor walnut shell waste getting into the chambers will have no effect (they will burn up through the combustion chamber and/ or catalytic converter). If a mistake has been made and a cylinder was blasted with the intake valves open, we would suggest that the vacuum adapter be applied and air-only be blasted through the blasting nozzle, directly through the open valves. this should agitate the walnut media and allow most of it to be vacuumed out.

Anytime the intake is removed, is a good time to replace the starter. Especially on E46 engines.

You likely just need a bigger compressor. The size of the blasting tank is only reflective in how often you have to refill it. If you run the pressure down and then have to wait for the compressor to run and refill the compressor tank, this is a compressor issue. A blaster uses a lot of air. We can run continuously with the blaster shown, but we have an 80-gallon two-stage compressor. Typical home compressors do work, but you will have to occasionally stop and wait for more air.

Would a (non turbo) 1993 325i e36 with 700k miles on it need this carbon cleaning as well? Currently, No Start with car running fine only minutes earlier. local auto repair shop thought I had bad fuel pump. I told them I've been smelling gas a long time and seen some leaking from electrical receptical on sending unit (full tank of gas) only days before failure. The shop said they thought I had a bad fuel pump. I already knew I probably had fuel sending unit, filter, and carbon canister issues ..... parts just added.... helped none in getting engine to run. So, they gave up because know one around local knows about BMW engineering.... said car is acting like it has jumped time. I hope they didn't disconnect the vanos oil line thinking its a fuel line and trying to crank it... it probably would jump time then. Who knows??? Now car is at a shop that does work on bmw's and I told them what the first shop replaced and said and they went in that direction and requested my permission to remove valve cover and check things below. So, they called me back said I'm getting around 50 psi first couple of cyl's. and 65 psi on rear cyl.'s..mentioned something about 143 psi. Said averaging 70 - 90psi and that is with the engine out of time. If it was in time the psi readings would be up in my opinion. They're leaning toward my engine is having issues with timing chain maybe reworking the head said maybe best to replace w/used low mile engine being nearly same price to repair.... WWYD with a 700k miles engine trying to get 1 million miles before retiring my lil toy? Should I replace timing chain(s), sprockets, guide, and tensioner myself at home or best to find good used engine low miles and have pro install?
