Hey all.
Driving my Antara a few months back and it developed a knock randomly in the engine.
First mechanic replaced a tappet and rocker, the car would then not start mechanic left puzzled.
Another mechanic has inspected and replaced the injectors (one found back flowing and another couple were not effecting the engine as much as they should when unplugged to test.)
Started back up, Knock still there.
Knock coming from the right hand side and after swapping and coding injectors the knock is in the same place.
Any assistance would be greatly appreciated, apologies for the explanation 馃ぃ.

Top end engine knock diagnosed to be oil pressure leak in the cam shaft supply.
Solved with quick gasket and tapping disappeared from the top end as the tappets are now pressurised.
Unfortunately prior to this we did a regeneration on the DPF which we think may have made the bottom end fail due to lack of oil pressure.
Another knock different to the first can now be heard.
Some said it could be leaking injector seals causing this but having a mechanic undertake a further examination to confirm the new knock diagnosis.
Will update
