FG XR6T engine bay ticking/knock

[PTR_NITRO_FG]

So a little concerned...jumped in the car today and noticed my car sounding a little tractor-like when I was next to walls/buildings. Got in driveway and noticed decently loud ticking...hoping its not engine knock or something bad?

 

Obviously the video is not a perfect indication of noise...but it was significantly louder than injector ticking. Weird thing is it comes and goes too (after video moved car into garage, noise went down, then eventually stopped, then turned car off then on and 10secs later the knocking was there again). 

 

Any ideas? Think the belts and harmonic balancer were replaced 3 yrs ago, hotside bolts retorqued 6months ago...cars still stock tune...150k kms though :(

I hope that's a collapsed bearing in the AC compressor or one of the pulleys. Turn the AC off and see if it gets quieter.

timings fakd m8, snapped a tensioner and chains flopping around I reckon

 

remove the serpentine belt and start the engine briefly to confirm the noise isn't any of the accessories as mentioned by robba above

Yep good point...kinda sucks cause no cash and if I had to do chain I would have hoped to do valve springs at same time. FML

 

Edit: also ran the X4 for faults and said none. Guessing a proper Ford dealership scantool would be able to scan for 50 billion more things?

Have you tried power cycling it?

[PTR_NITRO_FG]

Yes I did. Problem still persisted. Heres video after power cycle;

 

 

Good news is hopefully my aftermarket warranty should cover it. Apparently "all internally lubricated parts" should cover timing chain tensioner or whatever the cause is. Hopefully theres a chip in the timing chain so they have to replace that too. Not sure if camshaft lobe damage would come under that too...

 

Will report back next week on what they find and what gets replaced

Is the car fully log book serviced from the time you took out the warranty? 

If it isn't I don't like your chances.

[PTR_NITRO_FG]

Yes full log book serviced (owned since 80k). The catch is its "aftermarket" warranty....I.e. Ford get paid, insurance company always approves claim. 

 

Best $1600 I ever spent; claimed over 9k worth of work (so really 6k at any other mechanic lol). Only have 25k kms worth of warranty left though. 

 

But dont want to jinx anything, but fairly confident by what old mate said over the phone (he doesnt BS me).
