Deep dive into a faulty cam phaser …. Interesting video 👍🏻👍🏻👍🏻👍🏻

[@mazdaman1286]

since cam phases have been introduced I have changed many BMW's , smaller engined Volvo's and Renaults. I cannot recall changing one on a Toyota and maybe one or two on a Honda. I have disassembled Hondas and got them working because of missed oil changes gumming them up. Perhaps BMW/ McLaren etc should look at Toyota's method of doing things.....

This is the first time I've seen this fault, clearly explained. Well done.

[@jasonruch3529]

Thanks for explaining that! Almost every make and new engine uses those today and i always wondered what wore out.

[@russellshulin4682]

Great video. I can’t imagine the amount of time it took to figure it out. Well done!

[@jdmimportlogistics]

Apparently the Audi Group did some reinforcement around the pins to reduce wearing on the V10 R8 cam phasers

[@JSAFIXIT]

This may seem insane, But I know other vehicles have similar issues with cam phasers. One that stands out in my mind is the 5.4 ford triton v8. A solution they have come up with is using machined pieces to lock the phaser in place permanently. It doesn't hurt performance on that engine, but it's also not a twin turbo supercar engine.

Excellent video!!! I have more experience with Ford cam phaser issues and cannot stress enough the importance of proper oil changes on any vehicle with cam phasers/variable camshaft timing. Do you know of anyone "locking the camshafts" on a M838T or a M840T for very high HP applications?

[@icemannbmw]

So how does one stop this from happening? Is there a more robust Cam Phase that is available that won't wear down as much?

[@c8miamicarclub]

What can be done to prevent that? Millon dollar question

[@bentickner1]

what a great detailed video. I now know how these things work :) on a serious note what caused that wear? debris? dirty fluid causing the locking pin to stick? soft metal? It looks like it got worse over time until the lock became a ramp.

Just like cam phasers on the Ford 5.4 liter 3 valve engine. They make noise when bad

[@mjmiller1026]

Spring on pin is worn.

[@richardteraci3793]

Thanks for the explanation. What is the typical cost to replace these?

[@gilbertwashburn7095]

The mechanism looks well made maybe that one wasn't Harden properly

[@markhartman1475]

Any idea why it failed?

[@DJSmith575]

Oil starvation???

[@hangpilot1200]

How many miles on average for this failure... if there is one! Hard to believe McLaren owners are skipping oil changes ;-)
