Default N54 Valve Cleaning - 04-19-2016, 07:17 AM

I was planning to clean my 35i valves since last year. As in Portugal there are no companies selling the walnut blaster (ordering from the US is too expensive due to taxes and customs), I decided to do it by myself and started to gather tools and cleaning liquids.

The process took all day as you need to disassemble some parts and once the valves are closed, you need time for the cleaning liquids to actuate.

As I had already bought the BMS Meth kit and CP with meth bungs, I took the oportunity to replace the OEM CP and clean the engine compartiment. Pictures are attached.

What is that glass jar wit the hoses coming out of it for?
It looks like the manual method worked out well for you, that is a huge improvement!

That glass jar with hoses was an intermediate can that stored all the debris and oil coming from the intake in order to avoid get that crap into the vacuum cleaner.

This DIY took 5-6 hours but I got great results. Where there is no walnut blaster available, this is the best solution.

The process is similar to the walnut blaster valve cleaning, at least till you reach the valves (remove engine bay plastic covers, air filter box, diverter valves, chargepipe, throttle body and intake manifold).

Check which valves are opened and close it using some cloths. Then work on the closed valves (confirm using WFD40 and check if they are not leaking) and put injector/carburator cleaner inside and let it actuate for 20 min. After that use the vacuum cleaner to suck all the residues and use a steel brush to remove the remaining carb. Repeat the process as necessary.

Once you cleaned the initial closed valves, you need to rotate the engine and repeat the process for the other 3 valves. Once all done, mount parts on reverse order and enjoy the results: smoothess, better engine response and a more stable idle.

Regards

I am also thinking of doing it, the BMW in Sweden want $ 1,300 for blasting
which gaskets must be replaced when you do it?

I did not replace any because there are no gaskets on those parts.

That's incorrect!!!! There are 6 seals that come as a kit to seal the intake ports. I strongly suggest that everyone doing this removes those seals from the end of the intake manifold and replaces them.
We also remove the throttle body durning our walnut blasting service so that we can clean it as well as the inside of the intake manifold. We then replace the throttle body seal as well (the big green seal).
And, if you really want to be detailed you could replace the charge pipe to throttle body seal.

We replace all of these seals during our walnut blasting service and we also are now adding an RB external PCV system at the same time.
It's foolish not to replace the gaskets on a parts that only comes off the car rarely and requires a perfect seal to hold boost pressure.

So intake seal kit and throttle body seal are mandatory IMHO. Charge pipe seal is also an option but easy to change at any time.

My intake seals were in good condition (part no 11617547242). Car is running very strong and boost levels are normal with no leak (always on target).

Your comment saying that there are no deals on those parts is just a bit misleading to the DIYer. There are seals (I.E. gaskets) but you optioned to leave the existing ones in place after inspecting them.
The charge pipe O-ring is considered a seal as well and is replaceable. It looks like you purchased a new charge pipe that came with a new deal but for others that didn't they may want to replace the seal.

I'm not trying to give you a hard time but as a DYI it has to cover the process in a general way, not specific to what your particular car did or didn't need.

This is surely a great help to those that don't have the means to walnut blast.

The chargepipe comes with an inner o-ring. The seal is in the throttle body (green one).

Hey, that looks pretty good!
So, the wire brushes didn't scratch the valve bodies?

What size compressor did you use? How did it come out? Did you run in to any challenges?

new member here, long time BMW driver, always DIYer.
I've done walnut blast on 2 335i's now, I bought the bavauto walnut blast kit and I have a 60 gallon kobalt compressor from lowes. its not a bad process as long as your patient, cylinder 6 is a little tight but otherwise I think fairly easy (compared to removing the manifold on an e36/e46) just time consuming. I truly believe when BMW designed this they realized this they realized the PM needed so serviceability was kept in mind when considering all that needs to attach to the plenum.
picking up on the end of this thread here, definitely change the TB gasket and 6 IM O-rings. the charge pipe o-ring is easy to inspect so replace it if needed or for peace of mind, but many will have a different situation here based on PM schedules and if they have put an aftermarket CP in or not.
be generous with your solvents when cleaning the ports and use brass wire brushes, since the brass is softer than the head and valves it will not do any damage. do not use screwdrivers or steel picks to try and remove any chunks of debris, stay with materials softer than aluminum for that stuff.

I have 2 more buddies that also need the procedure done this summer, but if anyone near the central ohio area is interested, I have considered offering doing this on the side, PM me and we might be able to work something out.

Cool, thanks for the follow up. I just have a small 2.5 gallon HF compressor. It is great for trim nailing and airing up balls and stuff. But I do not think it would work for this project. My garage is very crowded, so I opted for a small compressor. Prior to moving I had the big Husky 220 volt 80 gallon from HD. I sold that prior to moving though. Just did not use it much.
I am contemplating buying a few gun cleaning kits and trying that method out, maybe using a power drill. I have seen a few that say that works pretty well, just a bit slower.

You'll still need that compressor for small blasts of air needed to help final clean each port.
I know many folks have found alternative ways to achieve the same results as the blaster, in the end i still use solvents too... so id expect the level of cleanliness amongst all the cleaning methods to be able to yeild the same results but the big advantage of using the blaster is time saved. Once i honed in on the feel of the wand and what angles im blasting at plus how to go about it methodically i found i could get a port clean in about 5 minutes.
Unfortunately for OP he has a logistics challenge that does not allow him the luxury of the blaster so i applaud him for his dilligence and still being able to get the job done when faced with adversity

Have just finished doing mine with gently scraping the worst of it off, blowing the chunks out with compressed air, following up with a good soaking of brake cleaner (I found that to be more effective than engine degreaser. Not sure what the active ingredient is but the brand is CRC), let it sit for circa 20 minutes before hitting it with an assortment of brushes (toothbrush, bottle brush, gun cleaning copper and nylon), sucked out the bulk of the fluid/gunk with a vacuum pump and paper towels followed up with compressed air. Then repeat as necessary. Very messy and time consuming, and this is my replacement engine on an engine stand. Happy with the results but I would definitely go walnut blasting next time if I can get the kit together.
