Direct Injection Intake Valve Cleaning

Рет қаралды 522,241

While I had the direct injected N14 engine out of my 2007 Mini Cooper S, I decided to remove the intake manifold and inspect the valves. I'm glad I did because I found that they were caked up with performance robbing carbon deposits.
In this video I show how I removed these deposits. I also talk about how they got there in the first place.
This video will apply to several vehicles with direct injection engines.
I had some help with editing on this one from Javan Hovind.

Something I did with my old Mazdaspeed 6 (which was also turbo direct injection) was a feed a can of Seafoam through the vacuum lines once a year, let it sit for about 10 minutes to help it dissolve the deposits and then take it for a hard drive to clear it all out. Seemed to work pretty well, I had the intake off at 130,000 miles and they were still in great shape.

I also have that Cadillac V-6 with direct injection. I never liked the idea of direct injection ever, however, but they do not make those Buick V-6s anymore. I have a 2013 Chevrolet by the way. It used to run great at 27K and 40 K and so on, but near 100K it runs a bit sluggish for sure, and I need a tune up anyway. I plan on doing it at home, once I get back home to King County, Washington. I am over here in British Burma where I spend more time now. Thank you. This was very educational and I had a feeling direct injection in some ways is a gimmick, but I cannot avoid it.

what if you didn't reroute the "out" of the catch can (or the PCV system) back into the intake of the engine? wouldn't that solve the problem with DI because nothing from the PCV is going back over the intake valves? i was thinking just feed a hose down to the bottom of the car from the PCV like those that drain A/C condensation.

Hi Eric...here is another method for cleaning valves we use on VW TDI diesels prior to egr delete. Pull spark plug and hook up compression test fitting in place and attach air compressor to blow high pressure air through cylinder. Rotate engine to TDC and walnut blast or chemical your choice. Walnuts work best for us...shop vac while you blast and when finished vac and wipe clean. Then rotate engine backward until compressed air blows all of the particles out of the valve recess. You would be amazed how much particulate "packs" around the rim of the sealing surface that you cannot see. Enjoy your videos very much. I have learned a ton. Be well

Great stuff! I have 2010 Cooper S. Same N14 engine. At 35,000 miles last year I had to have it walnut blasted. I’m at 58,000 and need it again... Not only is it on the valves, it builds up IN the combustion chambers, usually piston rings, humming them up. Most common code thrown would be superknock, even if the check engine light isn’t showing it. A simple, cheap, water spray for the intake manifold may help a lot. And definitely add a baffled oil catch can! The N14 should come from factory with one... XD Always enjoying your videos!

Dang, what a nightmare! I'd be worried about knocking off debris that ends up inside the cylinder, or caught on the valve lip that prevents a good seal. It looks like there's no alternative to do this better without removing the head. Walnut blasting sounds interesting, but with the valve tightly closed it would be hard to clean the edge of the valve well....

@malp6280 6 жыл бұрын

uknow you could open the valve & pour fuel into the chamber engulfing the valve.. the fuel itself would dissolve the carbon & you could vacuum the liquid out or manually crank the engine & allow the fuel to run our (after removing the down-pipe/cat) (doing this without the spark plug in would be the best idea however)

CRC intake valve cleaner works for me. My 2017 Sonata mileage dropped from 32 to 26mpg combined at 25K miles. I lead foot all the time. I bought 2 CRC cans. After treatment, mileage returned to 32mpg combined. Hot engine @ 2000rpm spray continuous till engine almost dies then turn off and let heat soak for an hour. Drive car for short trip and repeat 2 more times. I used 1/3 of the first can and got excellent results (32mpg again) and now WOT sets me back in the seat again. Engine hard starts and pings for the first block of driving during first treatment. After 3rd treatment, no more pinging, proof no more carbon breaking loose. My method gives great heat soak, blipping the spray can while engine remains running does little for heat soak. No ECM codes.

An oil catch can is what's needed. The bulk of the problem stems for the valve cover ventilation being fed back into the intake. This is done for emissions, but since direct injected engine intake valves don't get washed with petrol like in multi-point injection, the valves gunk up.

@afcgeo882 4 жыл бұрын

No, it doesn’t mean that. Those certainly void warranties, so keep that in mind. Multi-port injection engines don’t need them. Some GDI engines that are more modern have other ways to filter out particulates. I know Subaru has a patented centrifuge on their engines. I’ve heard new Hyundai/Kia engines leave pistons down every few firings, so it gets washed over with gasoline. All those slow the rates of deposits to where running meth is an unnecessary customization that may cause more harm than good. That said, many engines do still need some type of cleaning. However, it’s been proven that NO method prevents all build-up. Not meth, not a catch and not fuel/oil/TB additives. Eventually it will be time for a walnut treatment.

Thanks for sharing your work. Few notes about this method emerge though: Possibility of scratching valve seats(?) Carbon chunks may fall into the combustion chamber(?) The way I would recommend: close valves (rotate engine) --> pray some good cleaner--> let it soak --> vacuum (there is a tricky way to create negative pressure with positive pressure air gun!) Wouldn't recommend using those gaskets 5:56 (they are non re-usable) specially if they harden, which they will eventually will! Greetings.

@22_floW 6 ай бұрын

Late to this comment, I know, but it deserves more upvotes because if you media blast with something like walnut, the harder bits and pieces CAN cause damage if (more likely, when) they find their way past the valves since it's difficult to sweep all the bits out after being blasted if the valve train is still in the engine / bay. Also, if your vehicle has a turbo, the bits can destroy the impeller, but even worse, if they find their way into the bores, they'll scratch and gouge the lining, rings, etc., leading to even worse problems than what the carbon buildup might've been causing. (At least, this is all I've both read and heard from actual "gold" GM master techs.) Media blasting with something like dry ice or baking soda would probably be a safer approach if the engine / head isn't outside of the car allowing you to blow / sweep walnut out of the valve areas better. But with whatever media is used, you still want to sweep it all out somehow with some kind of narrow vacuum attachment. Considering visibility and reach, this is why it's usually advised to do this kind of job with the valve train completely off the block, that way you have better visibility and can do a better job with blowing / sucking everything out of the valves. I'm also skeptical of using things like picks and whatnot to gouge and scratch the valves for obvious reasons, but many use the wire brush drill attachment approach, which seems to do a good job if the valves have been allowed to soak in some kind of cleaner first. If not, the carbon might not come off as well. I've always been told that you should only do any of these things if you're seeing misfire codes (not the occasional single-digit amounts, but the kind that reach up in the double or triple-digits and don't go away or go back to zero count) or have some other justification to do it like insane fuel trims or stalling, etc. The every 30-50k mile regimen routine many encourage is something I've always seen car nuts and advanced DIY'ers advise, but if you go to any shop as a normal driver, they'll often encourage you to just "not worry about it" until a check engine code related to either misfires or something drive train-related comes up, which I also don't exactly like as this is the opposite of being proactive against issues that could lead to bigger problems. So, I'm not sure what the best approach is for your standard vehicle owner to take as this isn't a job any DIY'er can or should do as it encompasses many tasks one has to do to do it correctly (i.e. - taking various parts off, not damaging wiring harnesses or accidentally detaching various hoses, avoiding inadvertent cracking or breaking of things, using proper gaskets, using correct torque, etc.). Unless you have experience and knowledge of what has to be done, it's probably best to just do whatever your mechanic advises if it comes up, but I wouldn't listen to the advice of anyone who isn't at least a dealership-grade mechanic because if you let just any "ole' mechanic" do this kind of work on your vehicle, you're just asking for it.

it's literally what catch cans do. They catch the oil that comes from your PCV system. BMWs have breather filters, and newer TDIs have an incorporated one on the valve cover. Oil contributes massively to this gunk that forms on the valves @@atl3630

Faulty rocker covers allowing oil into the intake system are exactly the problem I have with my Mitsubishi 380. No easy fix, it's a bad design from factory.

At least I'm not getting the oil consumption anymore and the throttle body is spotless and engine runs much happier not sucking in oil.

I have a 2015 Mustang with the 2.3 L EcoBoost engine -- it's direct-injection, turbocharged, same as the engine in your Mini there... I'm very concerned that this will become a problem for me in the future. And it's not like you can just spray something into the intake, like SeaFoam for example, because anything you spray in the intake is gonna go through the turbo and destroy it... So if you were to try to use SeaFoam (or something similar) you'd have to figure out a way to introduce it *after* the turbo... Ugh... Sounds like a nightmare... Anyway, thanks for the video, though -- so many engines are direct-injection these days, it's important for everyone to know what they're going to have to deal with eventually.

I tend to the cars of my family and friends, as a hobby and because none among us trust stealerships and shops anymore, not with our lives anyways. Whilst i've 'steered' away some of them from DI engines, there's still 3 cars (one funnily enough a late prod Mini of the one Eric just showed). At the very least here in EU, i can't be bothered to care about these issues anymore, these engines are absolute garbage as far as i'm concerned and ALSO, i strongly believe that the only reason they exist on the market is to thieve more and more money from owners. Why? Because, like i said, at least here in EU, i, as a hobby mechanic, i can go in break up yards and just takes these intakes and parts in general off the hundreds if not thousands (across EU) engines that were trashed, and neatly stacked on racks. At this point, i cannot be bothered to do a repair job on the quick with those 3 cars, i simply bought 2 extra of each, and i replace them in the engine, and clean the dirty ones with baths and media blasting over months. I would never buy one, ever.

@UnlinealHand 6 жыл бұрын

In the Mini community there are mixed reports of Seafoam working or not working. And whether to put it in the intake or PCV hose. Personally I don't think it's a strong enough solvent on its own to take care of intake valve coking like we saw here in one shot. Maybe if you did it every oil change or even sooner but even then I'm doubtful. There either needs to be a constant spray on the back of the valves for a long time or some sort of physical abrasive action to clean the valves off. On my Mini I went for methanol injection partly to solve this issue (on top of the performance applications). I know nothing about the EcoBoost engines so I'd double check to see if maybe it's not also port injected on top of DI, make car manufacturers are moving toward using both on their engines to help with this issue.

I cleaned the ports out on a 2012 Impala 3.6 using a long reach brush set similar to the Bench Buddy but they’re a ¼ drive assortment of stainless/brass/nylon as well as various sizes. I had to use a long-handled screwdriver to dislodge some of it as well. Compressed air helped make the debris airborne so I could vacuum the ports and piston crowns. But of course I had to narrow down some PEX on a bench grinder to fit inside the spark plug hole and adapt it to my wet/dry vacuum. Applying air through the spark plug hole (via a cylinder leak tester) revealed those intake valves are leaking (easier to see by pouring a capful of Berryman B12 cleaner into the port and watching the air bubbles) So since those valves can’t easily be lapped…and I can’t even tap on the stem to seat ‘em better, my brother-in-law has a choice of a complete valve job, or just live with fluctuation at idle and hope that it’ll smooth out as he drives it. I’ll spray some cleaner just past the throttle body when I reassemble and warm it up to see if that’ll help clean the valve face/head seat. His mechanic wanted $800 to replace the bad injector and the new injectors only cost $116 (+ tax) for the entire set of 6 on Amazon, with a 2 year warranty and while it said aftermarket, every single digit and symbol on ‘em were identical to the original OEM injectors. Guess I lucked out. Except one Teflon seal was broken from a slice and the injector was scratched from whatever happened. It was the weekend so while waiting 2 days for a response, I twisted apart the old defective injector so I could stretch the old seal onto the new injector. Problem was, those injectors have double Teflon seals that go into the bore and since the lower one was good, I had to stretch the old one over that. Well an ink pen cap squeezed it back into shape and since the scratch was higher than the seals, it actually held pressure. Of course the seller wants a picture but they’re already in so I guess they’re off the hook for now. Back to the direct injection, it has been a learning experience, and like 4x4’s, CVT’s, and anything turbocharged, I'll add it to my list of things to avoid I installed an oil catch can on the PCV to try to prevent or slow down future oil blow-by issues but I can’t help but wonder if just using full synthetic oil, rather than a blend, or rather than dinosaur oil could’ve prevented the whole thing. Plus I’ve read oil change places pump the oil in too fast, and supposedly could cause the problem. I do all my own wrenching but I still haven’t learned to effectively utilize my new Launch X431 PRO3S+ scanner (that was accidentally listed for less than $100 on Amazon and the seller honored that price)

A clean, SHINY valve will stare back at you. DISCLAIMER: if the WD40 goes inside the cylinder; then you'll need to pull out the glow/spark plug, raise the piston to TDC, and WITH THE VALVE OPEN, blow compressed air through the plug hole to blast the liquid out.
