  1. 2014-2018 Mazda 3 Skyactiv Recalls / TSB / SSB
    I have just received a recall letter from the Dutch Mazda Importer. Apparently, there is a problem with the Air Inlet Valve. This can jam due to a build-up of soot and not function correctly. In some cases, the Engine Problem light illuminates and the valve goes to the open position due to the...

    I can't find a guide or even a picture with the location of the EGR valve. I'm having intermittent long crank problems and saw that some people fixed it by cleaning the EGR. I've changed the spark plug, the battery is new. Ordering a new MAF sensor is this doesn't work because I've already...

    Is "concentrated injection cleaner" important to the valve and injection system? In my country, the user manual from the MAZDA official recommended 2018 model to use the injection cleaner every 10000km. It's like a 150ml conc. oil put to the fuel tank. Is it important? Some experts say that...

    Does the 2.5L skyactive require valve lash adjustments and if so, has anybody done it themselves? I have done this on B series honda motors before so I have the gap shims for it and know how to do the job, but being a different motor I am curious to see what is different with these. Factory gap...

    When do you all suggest changing the valve? The owner manual says nothing. I only have 4000 miles on my 2018 Mazda 3 sport, but I like to write my own maintenance schedule and refer to it in the future as my time becomes more limited. Have any of you with older engines had issues? Thanks

    Hello, My 2011 Mazda 3 has about 240,000 miles on it. Somewhere around 100,000 miles, I started having trouble starting and traced it to a bad check valve in the fuel pump. I replaced the fuel pump ($500+) and the problem was solved. It was diagnosed by doing a pressure test and seeing how...

    Need to replace the canister vent valve, the one by the fuel tank. I can't see it from underneath, wondering what the procedure is to find and remove it.

    Since our engines are the Gas Direct Injection type has anyone done a cleaning of the intake valves? I'm in the process of doing it now using CRC GDI iVD Intake Valve and Turbo Cleaner. I'm at the 1-hour heat soak point right now so I though I'd take a break to make this post. If it all works...

    Hey guys need help. I noticed some oil in the spark plug hole when I went to change my plugs. I ordered a new gasket and went to take off my valve cover. Noticed that I had a crack in it next to one of the screws. Does anyone have a valve cover I could buy? Dealer wanted $250 for one. Also, I...

    I've been noticing recently that under moderate to hard acceleration above 4k RPM, my 2015 Mazda 3 with the 2.0L at 34,000 miles, has a "clattering" noise. I've seen a few reports of engine failure, but no one talking about this noise. In fact, it sounds very similar to the clatter of the engine...

    After many years of faithful service in the Florida heat, my 2009 Mazda's compressor died last month. I bought an A/C kit online with a new compressor, condenser, and expansion valve. I've since swapped out the compressor and condenser but I'm having trouble removing the expansion valve. I can...
