Amarok Timing belt failure...It's not good.!!

A first for me...But I guess there's always a first time...

[@rachelhovenden3669]

I watched your video before having to do a timing belt change. We just did a 120,000 timing belt change over Christmas 2021. Changed the drive belt tensioner also. I told the mechanic who did the job to only use Genuine VW parts on Our Amarok as I didn’t trust dayco. Now after driving for a month. Our drive belt snapped and shredded due to broken bolt in the tensioner. A different mechanic pulled the part off and it’s a dayco. I was not happy as I got quoted VW parts too. Luckily only driving a local blue mountains road doing 50km. No engine damage hopefully. Thank you Zig for posting.

[@ziggassedup]

Thank you Rachel for letting me know that...It's quite obvious that there is an issue with the bolt supplied in the kit...I hope there is no damage but I fear there will be...Good luck and thanks again...Cheers.

[@Badgertronix]

That sucks, but you're a wise man making it their problem. Too many ifs and buts that will turn into headaches for you.

[@ziggassedup]

Absolutely Johno. Cheers mate.

[@russellpurdie]

I watched this a while ago and ended up using the blue box anyway. I did 50 and less than 1/4 and it was TAF. Felt like it bottomed out wasn't going any further. Still running so far. Thanks for the vid.

[@ziggassedup]

TAF is what I ended up doing also...Blue box too but old hardware...Cheers Russell...Thanks for your feedback.

[@rockerpat1085]

That's a tough one!!! Bolt broke going in and even though it doesn't look over torqued, the mechanic always gets the blame!!!! Wish you guys luck getting the part manufacturer to pay for the damages!!! And yes I too use Torques bits as ease outs!!!! Work's great and as far as I'm concerned it's the best!!!! Keep Rocking it out Down Under Ziggy!!!!

[@ziggassedup]

The fact it drove for 3 days perfect is the point...If I broke the bolt it wouldn't have made it out the door...Cheers mate.

[@shawnmrfixitlee6478]

ahh, That sucks Zig ! Some of these modern engines just are not what they should be ..

[@ziggassedup]

Yep. Cheers mate.

[@MafiaboysWorld]

As soon as you told him to turn it I'm yelling "NO!" at the phone, then that first turn hearing the valves hit piston made me 😬. Ohwell, time for a replacement motor from the parts company for their shoddy product causing it. 😎👍

[@ziggassedup]

She did the damage when the bolt broke at 110kph . The first thing the rep did is crank it and said " We'll it still turns so toss a belt on it ".Cheers mate

[@MafiaboysWorld]

Cheers mate.

[@leonwardle9409]

An automotive insurance assessor told me that Subaru snap the bolts too, genuine/non genuine all with the same sad ending…..at least you weren’t instantly blamed - makes a change!

[@asicerik]

That sucks man. Awesome you were able to get the other half out. Although maybe it does not matter since it is pooched.

No room for error. Cheers mate

[@Tjousk]

I'm glad I have geared timing rather than a belt or a chain.

[@ziggassedup]

Yes . Me too.

[@leewood9209]

I have done two of these engines. The cam belt had jumped because the auxiliary belt had shredded, I replaced the cam belt but there was clearly no compression. Upon inspection the intake camshaft (The one without the camshaft pulley) had spun round almost 90 degrees. The rockers were all ok. I replaced both camshafts to be sure and timed it all back up etc etc which resulting in the engine running perfect. I also changed the aux belt tensioner as well as the water pump and full cam belt kit. Twice lucky or does this happen every time???

[@ziggassedup]

Cheers mate...I hate 'em...

[@russellpurdie]

my is way overdue, makes you wonder ir it's worth changing.

[@ziggassedup]

It's worth changing...

[@rokg601]

50nm + 90° is TOO TIGHT - Done a few of these and when attempting 90° I got to maybe 50-60 degrees when I refused to go any further as I could tell the bolt would start to twist/break with any more tension. There must differences in bolt grade or compound between gen and non gen kits or possibly wrong torque spec in manual. Very tight with 3/8 ratchet is all u want/need.

[@ziggassedup]

Yeah "FnT is where I ended up after the dust had settled...Dayco admitted they errored here because I followed directions...I finally used the original bolt with no issue.

[@Zer0we]

I now have the pleasure myself of going through this process. I feel your pain. You've earned a sub for your attitude towards this new shit haha 😄 This one at work has a seized ps pump which shredded the drive belt to pieces behind their silly fooking belt cover and got sucked into the timing belt section therefore spider webbing its self around the crank pulley causing the belt to slip out over 180° Codes for timing correlation, Almost guarantee I've got a few bent valves. This one hasn't chucked the rockers out though so I will look a little further tomorrow. 😉

[@ziggassedup]

Cheers mate...Have you seen the other vids on this job...I had quite the battle with Dayco over it...Good luck with yours and thanks.

[@rossmobilemechanicalservic3342]

Mate did one on a Triton tensioner failed after 10000 kms and they said nope to warranty due to belt was over tighten lol 😂 fuck dayco

[@petergoodwin2465]

@@ziggassedup seems like everything is junk these days. I put a new sump on the 327 in the impala, lucky I checked the plug before it went on. Thread was stuffed, tapped a new thread and perfect but lucky I checked or I'd be doing this again. They've got to stop making this stuff in China, its a joke. Looks like they'll be paying for the engine, at least they have admitted it was no good. I've had it with junk Parts, pushrods wore out in 20 minutes in the 327 . Plenty of oil and pre lubed them , pro form or some crap they sent her. Used Manley and never a problem again. Makes me worry about all the knockoff heads and Chinese parts all over ebay. Even the Devilbiss spray guns ,even says made in the UK and they look exactly the same even the box. Idiot government are quick to take tarriffs off our manufacturing but don't care about the illegal copies China does. Have a good one mate.

Don't go cheap on valvetrain Pete...It's more important than conrods...

@@ziggassedup wife got the parts sent ,used all good stuff ,scorpion roller rockers, Edelbrock heads, Lunati cam and lifters except the pushrods. Said made in the USA but this pro form crap is all Chinese. Upsets me because I thought it was the cam at first and you feel like crap.

Yeah they helped out in the end by paying for the head repair and the spare parts supplier payed for the gaskets...I covered the labor...When I finally put it back together I ignored the Torque specs and just did things up F'n tight..Cheers mate and good luck.

That's a bugger mate...When they told me "We'll look into it" I knew they would tell me it was my fault...I took it further and told the assessor guy he was a clueless goof and I want to get the bearing and bolt tested...Long story short, they covered the head repair, the parts place covered the gaskets and 5hrs of my time that I donated...I'd buy another Dayco kit...I must have fitted hundreds of belt kits in my life and this is the first time I've followed their instructions and first time for failure and I told them that.!!...

[@MissouriOldTimer]

I didn't know that VW used interference engines but I guess so,, it's odd that the 4 cylinder subarus are interference and the 6 cylinders weren't, at least in the older ones.

[@audionut9974]

All modern cars are dumbass only way to make decent power. Should be using timing chain though

[@closertothetruth9209]

it is a diesel though , sofar i havent seen a non interference deisel but non interference petrol motors definitely exist even some newer engines, no doubt on the internet there will be lists of zero interference engines,

[@MissouriOldTimer]

@@closertothetruth9209 honestly I don't know much about diesels. naturally the older cars with chains and gears were non interference, The SVX subaru I had was a 6 cylinder and it was non- interference, one of my idler pulleys broke , the engine stopped but nothing was damaged as far as I know, all the 4 cylinder subarus are.

[@ziggassedup]

Diesel engine leaves no room for error. Cheers mate

[@NikolaosLedZeppelin]

Can't understand why manufactures didn't make a non interference engines at least for their commercial line vehicles.... So a broken or skipped belt couldn't harm engine

[@ziggassedup]

That's how they sell parts.

[@lukecrane774]

Because everyone wants more power and torque... ya won't get that with a non-interference...

[@-DC-]

Aftermarket parts always a lottery the quality gets worse and worse every year, for something as critical as a timing belt kit OEM only from a dealer.

[@ziggassedup]

Lets see if they honor their warranty against faulty parts...First time I've had any failures in 30+ years of timing belt changes and mos have been this brand...

[@danielmarjanovic443]

That torque setting is way too much for that bolt,I have done dozens of these timing belts never torque it with a torque wrench,I also use European brand parts and never had any issue

[@ziggassedup]

A bit late to tell me that now Daniel....Cheers mate.

[@DineshSharma-nw6nd]

What is the correct mileage to change the timing belt?

[@ziggassedup]

Most are due at 100,000 km or 60,000 miles as is this one...

[@iporcupinetree]

A bolt...did the Challenger have a low tensile bolt that fucked and that fracture hit the tank fuel chamber .... Or blame a O ring? Professor Zig how do you comment ... What if someone died. Like the guy paid the lest is to answer

[@ziggassedup]

Yep blame the O ring...Ya can't do much more than follow directions so if a failure occurs it only leads to one thing...Faulty bolt or idler is all I can come up with but nope seems it was me according to them but a few Diesel engine pros have told me otherwise...They all say the bolt was bad and when the bearing expanded from heat it gave up...Cheers.

[@roberthrodleykambanda1983]

How often must I replace this belt?

[@ziggassedup]

100,000km or 60,000mls.

[@begilmezz]

If you use aftermarket brand like dayco every 100k(I wouldn't recommend that brand) but if you use OEM brand like INA VW workshop manual says every 210k. Whoever not agrees with y'all free to read Vw workshop manual. (After 2010 models only)
