Mazda Timing chain replacement tips

[@thecapedcrusader326]

Peter, I bet the local Mazda dealership mechanics watch your videos to better understand the cars they're working on. You are THE MASTER with these cars!

[@kennedysgarage3281]

Thank you for that Caped Crusader but not a day goes by that I don’t learn something new from Mazdas or other models. It seems a lot of people are having problems with them and the get twice as many views so I continue to upload them . Thanks again 🙏🙏👍

[@spencerhulme1203]

A true Gentleman and Scholar, what a gem find indeed, honestly and such a damn shame other mechanics are not like you! I am in the market for a Mazda CX-5 Sport on a 2017, it was such a pleasure to hear you speak in terms of how committed you are to the service of the vehicle. I was thinking i could drive from Wales to where you are should i purchase this vehicle for a timing chain replacement and service.

[@kennedysgarage3281]

Hi Spencer, apologies for the delayed response. If you do or have bought one, the only chain that fails is the oil pump timing chain. Simply due to its small size. Get the intake manifold cleaned and injector washers around 100k km or 60k miles. Exhaust camshaft at 150k kms or 90k miles, then that’s it. A good car thereafter. Happy new year mate 🙏🙏

Ahh Peter another 2.2 Skyactiv saved..😊 great job…that’s a good idea of the angle grinder on those pesky bolts/nuts on the ECU…I just ended up pulling the whole loom back and leaving the ECU and looms connected. One thing I noted about the cam shaft when I was rebuilding was that most of actual exhaust valves were so SO tight..it was very understandable as to why the shaft would have worn so badly…I’d be very curious to know how long a second cam shaft lasts before it’s ground back down if the valves are not removed and reseated…I know your into a much bigger job at that point..but just an observation and the curiosity side of me coming out 😊

I'm waiting for this to happen to my 2016 Mazda 6, 125k miles. Only last week I had the oil sump strainer and injector seals replaced after low oil pressure warning. Had them do what inspection they could on the oil pump chain after watching your videos, they said it looked fine at this stage but any examination can only be superficial. If I was in IE I'd bring it to you, but alas...

[@kennedysgarage3281]

If the timing breaks & oil pressure drops you will loose throttle control on these, which is a brilliant feature to save doing extensive damage. So don’t fret about what may never happen, it could last 10 years🤞🤞🤞

Good job, again. I have a rattle at cold i hope is not the chain but in case it is just wonder how much you charge for this job. 🤔

This is a hard question to answer, just replacing a timing chain would cost around €1000 but if you engine is noisy it could be the oil strainer and or exhaust camshaft/hydraulic tappets & both of these should be be done while the timing chain is off. It could cost another €1000 😬😬😬

Thanks for the guide. Question: is it necessary to put oil on new parts when we put it all together?

[@kennedysgarage3281]

It depends on what you feel is best. Some people would say soak everything in oil. I put oil on bearings but not on the chain. Simply due to it taking quite a few turns over before the engine fires. I feel this lubricates everything at a low engine speed, but everyone is different 🤔🤔

Few days ago I was driving along and as soon as I went over 2500revs the car started to shudder, I pressed the clutch and reved it up and it flashed up a load of lights and died in the middle of the road. Would not start, engined turned over with heavy shudder and no lights on the dash. I reakon it could be the timing chain! Have you heard of this before... Thanks David in Galway

[@kennedysgarage3281]

Hi David, these are very common events to happen. The engine is in need of tlc and then blocks the Dpf. Unfortunately people the fix or remove the Dpf but never look at what problems caused it to block in the first place. It sounds like you could have a heavily blocked intake manifold. Only oil pump timing chains fail which cause oil pressure faults. I’ll copy and paste part 1 of 3 videos on a similar issue I had. Or just skip to parts 2 for the intake manifold clean
