Mazda hardened the exhaust camshaft from around 2015/2016 because the original was too soft on the lobes. But many 4wd models were slow to sell and sat on the shelf, so shipped and registered later than they appear from the factory. If you have a 4wd model, even facelift, it can have a soft exhaust camshaft.
The newest we seen which had the worn camshaft was a 2017 CX5.
The service manager at my local dealership has a 4wd 2017 facelift model with a worn camshaft but it was actually built in 2015.
My 2016 cx5 also has a worn camshaft. Does this mean that I’ll get the hardened camshaft now when I have it replaced?
Hi! Do you know if deleting the EGR will increase the distance between DPF regenerations? Thank you for your content! With your guidance I carbon-cleaned my 2.2D 2016 Mazda 6. Thanx again!
Hi, can I ask what grain do you use for your walnut media - fine, medium or coarse? And have you tried Garnet? Its much much cheaper than Walnut.
I wonder why some exhaust cams don't wear and some do? I think oil starvation is the problem for those cams, and more regular oil changes and good injector seals will prevent this from happening. That's my spin on it.
They had a batch of bad cams from the cam manufacturer, these cams ended up in engines mainly from 2014 to 2016. Mazda didn't do a recall because, when in an engine, you can't tell a good cam from a bad one until they have been used so Mazda dealt with them on a case by case basis when the problem was discovered. If your mileage is low enough and you can prove the engine was serviced correctly then Mazda should fix it, otherwise you rely on the excellent work that is done here. Mine had the cam go at 63k kms (which basically means it was wearing from new) and the oil was changed every 5k from new.

@@L8xG6 Hopefully you will. Mazda are on the 3rd revision for the camshaft (B at the end of the part number). There are also 3rd party camshafts if you want to try them instead of a Mazda one.
Thanks mate
Interesting MPG on this car. Just curious if it's awd or fwd. Mine is AWD which are well known for lower MPG compared to FWD. I have had similar MPG before remap and lost about 5 MPG after. Things got worse while the carbon built up in the intake reaching about 38 before you've done the carbon clean. Now I'm in the region of 43 predominantly city driving so I'd say it's a good improvement.
This one is 2wd. After the carb clean on the test drive I averaged 62MPG ;)
Incredible MPG on fwd models 😮
Stay away from these 2.2 skyactive diesel cars
Only if they are not maintained and driven properly, only use ow30 supra dpf oil as recommended and change the bloody oil regularly ,I drive the shite out of my mazda 6 2016 skyactive d mainly motorway 280 kms no issues 8kms oil change by me .not an engine for potering around town .😊
@@mickmaher3875Did you ever have to change the exhaust camshaft? 280kms would be great if you had zero issues
Hi,saint,excellent content as usual,you use an after market map sensor or genuine mazda?
OEM Mazda ;) we found that cheap sensors just give more trouble.
@@MrNiceGuy94 how much please and where from?
from Mazda, it is slightly above £100
Thanks buddy,I'll take a look
I bought a quality genuine Bosch MAP sensor made in Japan off eBay for $68 Australian dollars. Mazda quoted $233 for pretty much the same sensor it pays to shop around as long as it's a quality product.
