Ray, I have found that when taking nuts off studs on exhaust manifolds and such, first. run a thread chaser over the exposed threads of the stud to get at least some of the rust and corrosion off, so you don't have to drag the nut across that too. It can make a big difference, at least it has for me many times.

Minimize the risk of snapping the studs/bolts that are rusted. They get awfully hot when removing else due to friction.

We had a Datsun (by Nissan) 510 back in... 1989-1990? It was like an '79-'80 maybe? Got a clogged cat. We didn't know much then. It would idle, but if you wanted to go, you had to have super high RPMs. My husband, boyfriend at the time, parked it blocking his dad's garage. His dad moved it to get the mower out, parked it, and shut it off, in 1st gear, and walked away. Next thing he knew, it was on fire, and hopping towards the house. He had a fire extinguisher, and used it up, with out effecting the fire. So he shoved it under the front tire to stop the car from setting the house on fire. The clogged cat caused the whole thing. The fire melted the ignition wires in the steering column together, so the starter engaged.... That was a CLOSE CALL!!! We never made the mistake of ignoring a loss of power again.

PB blaster was my favorite while the thrift store had it for $2, then came Liquid Wrench for $1. Great video, Ray.

Well good morning Ray I myself have a 2009 Mazda CX7 turbo and it runs great thank God

It looks like your Shop is hoppin'. Great to see!

We had to fight collapsing interior exhaust walls in Ford LTD’s. I just got to where I would drop the exhaust lead pipes from the manifolds and take them on the interstate and find out real quick. Ford only wanted you to replace a piece at a time but after getting a warranty bill for the same labor over and over they got smart and replaced the whole exhaust. Back then there was no stainless steel exhausts yet.

First Mazda subject vehicle I have seen on any auto channel in quite awhile. I've had 2 Mazdas. One new and one used, the unsung heroes.

As always.... you're a good teacher.

I briefly had a Mazda GLC Station Wagon and the pipe off the manifold had to be replaced and it was a dealer only part. The local dealership was also Porsche/Audi; I ordered it from them and when it came in I didn't bring the original in with me, and of course it was the wrong one. When I came back, there was a guy who had picked up his new Porsche and it didn't have the floor mats, he told him they'd overnight them. When I got up to the counter, of course they couldn't overnight my part and ended up having to drive it with no exhaust for a week and a half. I was really pissed.This brougt back memories of that.

Yes that exhaust hanger tool is a great invention

1:37 from this camera angle I thought you were going to collide.

My dad always said that the right tools for the job is the job half done. And knowing where your tools are is the other half. Best regards from Denmark

i must say, even though Ray was many times right in the past videos, i didnt believed him first when he measured the temperature until the cloth test.

Haven't watched all the video yet but my go to for diagnosing a clogged cat was popping an O2 sensor out. That allows some flow to be restored without huge workloads usually

Very interesting Ray !

Ray! When learning basic electronic troubleshooting one first step (after visual inspection &.voltage/ground) was 'half-split.' I.E. look for signal HALF WAY between start and end.

I have 2007 CX7. Cannot wait till next .

5:16 ECU RESET Every time you disconnect the battery the ECU recorded data is erased... a trick usually done when changing BTU/Octane rating on the fuel being added (for racing on the 2.3L DISI) On the CX-7 this result on the Traction Control and AWD/Traction lights turning on... something which will be fixed by turning the steering from extreme left turn position to the extreme right one. Also the automatic windows get disabled and one must manually lower them and then rise them using the button with the automatic pressing mode (just a little) Radio presets will be gone 😅

I enjoyed this video. Have yourself a great day, Ray.

dont know if there is new help, but the new side was hid, but there seem to be more light where the new door is to go....and there was lots of noise comming from over there.....good job at hiding the evidence....lol stay tune folks...same Ray time and same Ray channel.....some will get the pun and some will not......lol

good troubleshooting skills very good

Ray, so much respect too you. Been here since day one. But you still in your older experience have not realized what an air impact hammer does to stuck exhaust nuts. Always try air tools with hammers before weak electric 3\8 ratchets. Air tools win every time buddy

Always check to see if there is a banana in the tailpipe first! :)

Love Ray's vids! Don't miss the phone 🤣🤣 Really glad to see how the new biz is doing!!!

@10:30... Project Farm settled the penetrating oil debate. Gibbs is the best, followed by Liquid Wrench then Seafoam. Also, pre-soaking fasteners and letting them sit for 24 hours makes a huge difference in breakaway torque.

Hi Ray just finished watching video excellent learning about cat learning’s a lot thanks and as always you and families be safe 🇺🇸🇺🇸

Ouch. I have the same (ish) motor in my Mazda, and those cats are not cheap because they're built into the turbo down pipe. You have to replace the whole thing.

Shop is looking busy!

Yesterday was first time I ever walked away from the snap on truck without feeling bent over. I got a Snapon Modis Ultra for 295. Its even got 2022.4 update

Those Mazdas with the 2.3 turbo had an injector problem. They liked to clog up especially when it stood for a while. You can try to clean them but easier to just replace them. If you have lean codes you should take a look there and of course spark plugs. Trying to help. Im working for Mazda almost 10 years here in Poland and had a couple of them

This happened to my dad's 1973 Chevy Caprice back in the day. My dad thought the transmission was going out, and so did the guy at the transmission shop . After getting the TH350 automatic transmission rebuilt the car had the same problem. It would kick down to the passing gear but not upshift until you got out of the throttle without much acceleration. The transmission shop made some money off my dad. He took it to another shop and explained what the car was doing and the mechanic told my dad to rev the engine while he put his hand over the tail pipe. He told my dad this things not breathing right. My dad took it down to the muffler shop and had his buddy put dual glass packs on it. We didn't know that a 5000 pound battle cruiser could do a smokey burnout. Lol I found out later that it had a small block 400 in it when I checked the numbers on the block. No wonder

I had the issue on my early 70 big chevy wagon. They had factory installed double wall exhaust pipes, if you ran through water when the exhaust was hot the outer pipe would contract just enough to collapse the inner pipe, but the outer pipe would remain round. I was lucky enough to work next to the base motor pool. The mechanics asked if I had run through a mud puddle before it lost power. When I told them I did, they said change the exhaust pipe. I cut open the replaced pipe, the outer pipe was perfect, but the inner pipe was completely collapsed restricting the exhaust. Boy, was I relieved to only have to replace a section of pipe. This is a case where experience saved the day.

Been watching your video and do not expect you will handling cx7 turbo (my family car). Good to see some or more action on this car. This is a beatiful suv but bad design on the engine and turbo. Replacing parts will take ages (if you know what i mean). I may give you some tips on replacing the PCV valve (which nearly kill us when the car goes lean on interstate with max speed 45 mph) and top up with premium gasoline.

Hasn't it gotten old for you to have to manually open and close that gate every time that you go through it? Love watching your videos.

I notice, when you're opening the car doors on the lift you're having an issue with keeping the door from hitting the lift. No way to fix that without a 4 post lift. But, you might take some pool noodles and cut and put piece of them on the lift arm sides so, if a door hits it won't hurt a thing. Not sure how you could do it but I'm sure you could figure out how to put some on, and it would keep worries about hitting doors on the lift out of your mind. I think I saw a rubber boot like thing on the lift but I'm sure it's never in the right spot every time. Usually aren't like those side trim pieces on some cars that are never in the right spot when someone beside you opens a door and bangs yours....lol.

@7:25, just an FYI, most people don’t know that cheapie IR cameras like yours cannot ‘see’ the temp of aluminum, or copper, or stainless steel, especially if they are shiny, but most times even if they aren’t that shiny. Those heat shields at generally aluminum for that very reason, so they reflect the heat BACK into the CAT. Or should I say ‘nice and shiny’? Anyway, you need to have an IR gun/ camera with an emissivity setting to compensate for how reflective the metal is. The metals I listed are have very low emissivity, so they tend to reflect YOUR OWN body temp back, think of them as being mirrors reflecting long wave infrared (heat), so you only see heat from other sources in the room. Most people don’t understand how these things work and they believe the tool. Try a test, paint a black spot, flat black is best, on a piece of aluminum, and check the temp off the paint, and on the paint. It won’t even be close! Good luck!

On the edge of my seat for this one!

Probably the absolutely best argument for BEV and against ICE: exhaust work.

That catalytic converter isn’t going to be cheap either. Hopefully, Mazda can get one in a reasonable amount of time.

Old video but I'm on backlog. You needed to give the front cat a treatment we in Finland call "rautakankikorjaus". You ram a long steel bar thru the cat and empty it out.

Your diag vids are my most favoright 😂

TORCH !! I used to yell that in the shop , its like saying MEDIC !!!

Traction control/TCS malfunction indicators are perfectly normal when the battery goes dead on the CX-7. Only requires that the truck be driven/shut off and restarted and that clears the fault....yes I own an '07 CX-7 touring edition AWD with 98000 miles on the clock. Disappointed that my rear wheel bearings failed at 70,000 miles, the drivers side front bearing is now bad and gonna replace both along with the CV half shafts (one is clicking) along with an A/C leak, noisy serpentine belt idler pulley (gonna replace it along with the tensioner) and do a full brake job while everything's apart......fun to drive but crappy to maintain.

You're busy enough to have hired help. Awesome!

Working on vehicles in Canada. Every bolt you deal with is like a stuck exhaust bolt.

That’s a Ford 2.3L engine in which means most of the vehicle is FoMoCo. I have an 04 Mazda 3 Hatchback with the Ford 2.3L and most of the parts are FoMoCo. My upstream cat from Mazda costs $1000 and $200 to install from a smog shop and the cat said FoMoCo also buy oem O2 sensors which are expensive as well $170.

Ray you can also confirm a clogged cat if the exhaust is hot and sticky/ moist. When my daily started losing power I just went behind the car and felt the exhaust and was like yup clogged cat even confirmed it more by unmounting the cat from the manifold and stuck a scope down and saw it clogged to hell lol.

My amateur hyporhesis: Really good techs like Ray can salvage auction cars; repair them: sell to make a huge profit.

Surely somebody makes a downpipe and high flow cat for that motor. As long as you gotta go through the trouble of pulling it out, may as well get some extra power. Maybe throw on a JB4 while you’re at it. 😁

these 2.3 engines are direct injected as well. They suffer from intake valve carbon issues and the cam driven fuel pump can also have issues. There is also a torque/acceleration dead spot around 2500 rpm on some of these cars with this turbo engine. the cat right off the turbo, if you need to remove it, you will most likely have to remove its heat shields AND disconnect the engine mount and lift the engine to get it out, especially if it is AWD.

Great video Ray! Really enjoy your channel and content!

Love B'LASTER PB. I just have the luxury of soaking exhaust studs the night before and the morning of the day I work on them. I'm guessing at some point you'll have to rename your business "Ray's Auto and Exhaust PITA Clinic".

Apparently, a 5-50 mix of acetone and ATF is the proven best. Just came across an old machinist article where it beat all commercial products.

Given most situations on a vehicle, probably having to remove anything in the exhaust system would be my last ditch effort or enough to make me think twice if I want the headache. Some bright engineers need to redesign them so they don't meld together and require torches, extreme heat and dealing with broken studs and such. At least you have a lift. I've only done them on the floor, being a home mechanic.

Ray be like: "I smell rotten eggs." The one time there's a bad smell in the car and Ray can legit blame something/someone else. Nice.

@ 13 minutes, perhaps some lube on the exposed end of the bolt and between the flanges as well as the head end of the bolt that you were lubing, might have be of assistance to remove the bolt. Advice is free. IRONICALLY, A Mazda CX-30 commercial is running between segments. Hmmm. Have a great day, all!

I am going to guess by the new coils (prior repair) it was run with a misfire for a while, dumping fuel into the converter and melting it down. Or not, lol. I have seen this happen with the Ford Escape 3.0 engines. Hope we get a follow up on this one.

Good point. Sometimes check engine can be lit for weeks or months before someone checks the engine.

My co-worker bought a CX-7, nothing but dealer/warranty issues and conflicts. He had 2 puit premium fuel in it, dealer claimed he fried the engine by putting in regular. Dealer claimed that it neaded lead in the fuel, he even added octane booster 2 the premium at the "dealer's" instruction! It was running lean, burnt the valves!

I have the 2008 model of this. Fairly peppy car when it's not clogged. I think it's rated for close to 280 horsepower. Terrible on gas though and takes premium fuel.

Have to determine why the cat got plugged, mostly likely an oil burner so that issues will have to be addressed also or there is no point in just fixing the cat.
