@@QuantumRift its not impossible to do. I'm doing it now installing aftermarket camshafts. Just enough room to get a ratchet wrench in between the front under sway bar and the crankshaft pulley. First you have to move the coolant reservoir and intake box out of the way. 2016 miata
Hello, Great video thanks for posting I have one question I will need to replace exhaust vanos too and I am just wondering if it is keyed or some special tools is needed, Regards, Milan
It depends alot on the age, mileage, and treatment of the car. A car driven gently and maintained regularly won't have timing chain problems for +250k miles. A car rode hard and put away wet without proper maintenance might break or stretch a chain past the tensioner's limits at 150k.
Is that the same for R2AA engine ? 2.2 diesel ? - my Autel tells me that there is missal ligament of 11.1 degrees between camshaft and crankshaft! But car ECU does not warn me of timing chain ! When chain needs to be changed? Thanks
Good to see Mazda went back to a keyed crank. The non-keyed design on the 2.3L motors was so silly and made timing it an absolute pain. If you only had to remove the crank pulley you'd have to retime the engine, which was a major PITA on those engines if you didn't fully understand the process and that's putting it gently.
why do you align the cam pulleys based on their marks with the engine block when later on, when installing the chain, you change it again based on the marks of the new timing chain ? Because then, the alignment of the marks do not fit with the block any longer (watch 2.55 - 2:58). Looks weird to me and like a useless step that just confuses.
Probably because of the variable valve timing and cam phasers. The initial alignment helps get the proper sprocket tooth in the proper chain link for each sprocket. If you simply relied on just locking the cams, it would be very easy to get one or more sprocket teeth in the wrong place because of slack in the chain.
They made a mistake during the installation. @3:08 you can see the timing mark on the intake cam correctly positioned again, they just don't mention it in the video.
If the car owner does change the oil on a regular basis, the cam phaser maybe damaged, or the chain experiences excessive wear then the engine timing will eventually get out of range. The ECU will warn you of this. This is when you will need to change the timing chain. Often, when the phasers may need to get replaced too because it's damaged.
've heard every 100,000 miles but if you have changed the oil and filter every 6,000 miles and had maintenance on a regular and consistent basis the timing chain should last 200 or 300 thousand miles

I think a lot of people would do good to just cut in half the service interval that’s recommended for normal driving but is more like perfect conditions, and regular driving is more like severe service
That's the cleanest engine I've ever seen!
Yea, would be a lot more impressive had the engine STILL BEEN IN THE CAR while doing this....LOL.
The engine in the video is new... Used for demo purposes

Great! Now, I need to figure out how to remove the engine without a garage or expensive tools.
Hahaa
Did u ever figure out how to do that ? 3y later I find myself in the same boat ! (Jokes)
@@orlandoautoparts2993me too... If anyone has the engine removal procedure and head torque specs for a 2016 cx5 2.5l vin y.... Please send me a note
Well thanks for showing us what to take off and how to do it! Because our cars have the timing cover and everything assembled!
Good explains thanks
Any videos that shows how to remove the engine completely, and the collection of tools and lifting equipment required?
Does the 2.0 , gasoline also have cam lobe oil sprinkles ?
I'll sprinkle your lobes xx
is it necessary to replace timing chain? i thougth they last a long long time or never need replacement.

I don't need special tools to replace and align the timing chain? VW should take note of this.

Is this a 2.5?
Is the chain lubricated??? Running dry? OMG.
of course it is.. this one is only dry because it is used for illustration purposes.. it would be messy if it was an actual used engine

I thought that was ford idea for non keyed
@wingitreview you're right, that was Ford's design.

I though the same thing

@@BKD70 I am really confused too I still dont understand why they use two ways of setting of the chain?
How often must this be changed?
As far as i know there is no change noted in the service plan - should stay on there for the life of the engine.

If the car owner does >NOT< change the oil on a regular basis
Theoretically should outlast the car

Mantap bosku
Can u upload for cx9 tc timing chain?
Good one
Why not use cam lockers to keep the timing from slipping and just Chang out the chain

I guess you dint change lower chain then mot very much detail tbh
Hi there
Is it engine code P5?
Thanks

You shouldn't have to replace the timing chain. It is too weak!
if you dont look after your car then yes this can happen with any car with timing chain
