Part 2 of 3 of replacing the timing chain and rebuilding the turbo on a 2009 Mazda CX7 with the MZR 2.3 DISI Turbo (L3-VDT) engine. Replacing the stretched timing chain. Most people replace everything when they do this, since I'm on a budget I'm using a slightly different method to replace only the broken part (the timing chain) without removing the VVT or cam sprocket.

I want to say thank you for your videos on the cx-7 pfun. The family and I have the same issues and although we have a Civic as a great running backup, its a small car, this 2008 cx7 has been sitting and being unused. Yesterday, I took off the lower cat and saw the carbon gunk. I see the huge amount of oil in the inlet housing for the intercooler. Turbo is shot, looked just like yours. Car is sluggish with very little power to pull into traffic and takes a mile to get up to 65mph. It will not rev like any vehicle while it park, it slowly ramps up and boggs down. The car was displaying bad behavior, so we stopped driving it. Bought a scotty kilmer suggested THINKOBD 100 on amazon for $40, nice unit. Hooked it up to our perfect running civic, wrote down every live data value (37 of them) and also the values when I accelerate to 3000rpm from a 760 rpm idle, while sitting in the driveway air cond on. Then moved to the CX7 and did the same thing on my paper. This showed me a good value compared to a bad value with voltage, temp, pressures, fuel trims short and long...etc, by the way 3% short term fuel trim and 21% long term fuel trim is not normal, I read this two values need to be at or close to zero as possible, its how much the ecu is feeding the injectors so to save the engine, based on the maf and o2 sensors. I learned a lot doing this back and forth on the two cars, it did take more than a couple hours and glasses of my wifes sweet tea.
Pulled the codes on the cx-7 and got p2177,p 21278, p301 misfire, p0137 o2 sensor low volt, p2096 post cat fuel trim lean, p2187 sys too lean bank 1. With that info and your video, today is the day I pull the turbo and the cat that is attached to it. With your 3 videos here and videos on youtube from World Mechanics, Auto Repair Guys, Eric the Car Guy and others, I believe I can get this done. I have this week bought: 2 new O2 sensors, new air cleaner, new MAF, took out the pcv valve (and replaced w a new one from UNDER the vehicle which took 1 solid our and was very tight and difficult without breaking the clip), bought new ignition coils also, all this and when starting the car, it did the same thing w codes erased. THis tells me I should have watched your videos first or brought it to you ;-) Im writing all this to say thanks for your videos and to help the next guy or gal attempting to fix their 33K dollar grand touring car (way too much money for this mazda/ford tech). The update on parts...I ordered a new Turbo Charger K0422-882 for Mazda 3 6 CX7 CX-7 2.3L MZR DISI 53047109905, it will be here next week, i'll chime in here and tell you it solved our problems and I also ordered a new Cat Mazda CX-7 2.3L Manifold Catalytic Converter OBDII 2007-2009 DirectFit 5H40880 to go along with it. I wanted to do what you did here and replace the cartridge but for $150, ill try the china version...why? well this borg warner oem junk only lasted 88k miles on our well taken care of car, so if a China one lasts 20 to 40k more miles (after fixed) I'd be pleased with that, because I know what to look for now. I was going to clean the cat scotty kilmer style, but thought, the hell with it, everything else will be new, it should be new too. I havent looked at the VVT timing issues and faulty ecu mosfet problems I keep reading about, errrr. I sure in the hell hope for a positive result here PFUN, because im using dozens of red towels taking whore baths at the kitchen sink with gojo super max and lava soap , my wife is losing faith in my, "honey, I'm gonna fix it" skills and I keep drinking up all the sweet tea in the Georgia summer heat.
After doing all that, the car still has the exact codes after erasing and driving. Still minimal power. Must be fuel delivery/pressure or timing/ chain issues. Getting tired of it.
Beautiful presentation and explanations! Your attention to detail is much appreciated, thank you!
Man thanks a lot beautifully explained part 1 and 2. I will be doing my Mazdaspeed 6 very soon and with your informative video it’s just made my level of competency go from 4 to 10 thanks a lot.
Nice work. Trying to do the same exact process right now. Thank you sir.
🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️🤦🏽♂️ I’ve been trying to get the nut loose for 1hr never thought of just trying to slide the chain off and it working thanks for this video 💪🏽

wow, your engine is so nice and clean!.. Great vid! With you had one for the crank shaft replacement.
Thanks man. Good work
Thank you for share this information...
great job!
Excellent video. Great work, pleasure to watch it. Just one comment, extra verbal info when you were applying RTV in few spots during valve cover assembly would be nice to many DYI mechanics (why and where). Some of us dont know this. Keep up the great work. Im about to do my mazda6 2.5L timing cover reseal, its leaking slowly. Thank you.
Nice video sir....
Good job
How do I know if the thermostat is bad?
Thanks for the video mate.. hope you can make more vids for mazda cx 7 like valve clearance adjustments. TIA
I try to followed instructions but the knocking did not stop? I notice two dots on the crack haft and the rear sprocket is there my mistake? Thankyou
I wish you were my neighbor! I am tackling the exact same thing with my speed3 except I need the vvt not the chain.
If you can keep the chain tight enough you may be able to do the VVT without pulling the front cover. Don't quote me on that though.
VVT actuator isn't bad. That's why you change all of it at once. May as well do a timing kit bro, seriously you will thank me in the long run.
HOW MANY KM DID THAT CAR COVER?
Hey i like your video you did a wonderful job and so I have a question i had gotten a mazda CX 7 knowing that the timing chain was bad so when i got it from the dealership they had a repair shop so i told them to fix it but when i got it i drove it home a mile down the road so when i had enough money to get it fixed I drove it back and they had it for more them a month long story short it doesn't start and the had to tow it back to my house and they tried to charge me $900 i told them i agree that you worked on it and i owe them something so we came up with a price and i paid it but my question is do you think they had done something wrong that now it dosent even start the i know the answer would be yes but i just want to know what i should do and if i should bring them to court because no matter what they didn't fix the problem they made it worse so
Is it not way easier to put RTV on the cover as opposed to the engine?
Where are you located I need my cx7 worked on
PLEASE HELP; I also replaced the timing chain, tensioner, vvt diamond washers etc. Made sure it was at tdc and everything is spinning freely. However when i try to start the engine turns over but doesnt catch just spins. Cams and balancer are spinning in sync. I cannot put my finger on why it qont start. Any ideas would greatly be appreciated.
Start with the simple stuff, a unplugged wire or sensor, pulled fuses or relays.
Hello, where are you located?
Very thorough. What led you to decide that the chain should be replaced ? Are there mileage thresholds that mazda suggests to replace a chain ? Is it possible to complete the replacement on the vehicle ?
You can hear the chain slapping the inside of the case and all the symptoms fit the tsb they have for a stretched timing chain.
How important it is to change or not to change your washers That's the friction washer I'm talking About
You could probably get away with reusing them. But if you don't get away with it you'll likely lose the engine.
Great video, thanks for sharing. I've had the VVT and timing chain replaced 3 times by Mazda in the past 6 years. It seems to last about 18 months before it starts to make noise again at startup. Considering they want $1900 to repair it each time, I am hesitant to get it done again.
Curious, would you say the timing chain itself is the source of the noise if the VVT actuator is fine? I am also getting a P0012 code. Are these related?
For what it's worth, I have already replaced the VVT solenoid and cleaned the tiny mesh oil filter and the code persists.
Jason G how long does it take to change the timing
great video. i appreciate your time and effort to help others.
my car has the same problem. it cranks but will not start. when i connected the OBD, it says i have change the fuel pressure regulator and fuel other sensor which im in the process of doing. when i removed the engine top cover, i discovered that the timing chain is extremely lose. i think i will go ahead and check the VVT today, timing tensioner to see if they need to be replaced.
can i get your contact please in case i need further guidance?
thanks.
Just message me through youtube, I usually check daily.
Im having trouble finding the fuel pressure regulator.... i removed the intake to have access to the fuel rail and i still can't find the fuel regulator..
Any idea?
@@tchounkem.6199 Frome what Ive read these cars don't have a standard FPR , they have a spill valve on the high pressure fuel pump, a high pressure releif valve on the rail which returns fuel to the high pressure fuel pump, and a fuel pressure sensor on the rail.
Oh ok i see...
I bought the actual FPR from autozone though... so there is no place to actually mount it?
Curious, would you say the timing chain itself is the source of the noise if the VVT actuator is fine? I am also getting a P0012 code. Are these related?
Timing chain can cause startup noise as well. p0012 refers to VVT but it's possible that a badly worn timing chain will allow the timing to move enough that the actuator can't function properly. Typically the VVT actuator will show signs of damage on these vehicles.
If you are popping that code I'd stop driving it until you fix it.
Did you have a lot of vibration with your engine before the repairs you did?
It runs a bit better but there was no vibration. Just noise.

What were the special tools needed?
Just buy the timing set. Comes with all the tools you will need. The crank peg, Cam tool, harmonic balance puller and lock.
Anyone use the timing chain kit suggested in this video, if so how long has the car run without issues? Just skeptical on the parts since its an interference fit engine.
This one ran until 124k when the Transmission let go. I put a transmission in it and sold it soon after.
Always use OEM parts in these.
Before pulling the chain, use a paint marker to mark the location of one tooth on each camshaft sprocket, then count the number of rollers between the two teeth, when you install the new chain, be sure the count is the same.
It doesn't work on these since none of the sprockets are keyed. since the lower sprocket is held in place by the dampener as soon as you loosen the bolt it will have to be retimed. That method works so long as the sprockets are keyed .

You really should replace all those guides and tensioners, and VVT actuator . Those are even more notorious than the chains stretching. You not replacing the timing chain tensioner itself too is just a bad go. You did a good job but you skipped many wear and tear items that come in a timing chain KIT. All those plastic guides needed replaced bc the oil and heat makes them brittle, so now you aren't going to get the expected life out of that chain. Guaranteed you will be in there replacing one of those internals you skipped . The whole kit OEM is $100.00. all in all you did a great job but you did skip alot. C+ also the valve cover on these have a rubber gasket, why you use RTV, I couldn't really see what you used but it didn't look like you used a gasket.
Es el mismo procedimiento igual que el motor de mazda 3 verdad
Good job
