alloytec issue....d side rockers burnt n yuk/ p side clean n healthy....HELP PLZ

[Bowman2017]

cold start/hot start no difference but only on start up.... i get a rattle/knock sound under rocker cover (driverside) sounds like a diesel last for about 1 second then normal, started getting noisier over past 2 weeks its almost like the timing chain slapping a little. it has that kind of rattle noise, on inspection iv noticed the driver side rocker gear n cams all look alot different than the other side, it looks like the oil hasn't been changed as often as it should be n looks dirty n burnt its like the oil on the drivers side rocker gear has not been cycling properly....

cam chains has been done previously 210klms cam gears perfect,
i don't believe its a timing chain issue again there tight no play. cars running perfect no faults nothing, if u couldnt here the noise u would think its perfect, n cars been serviced on time every time since new, if its needed something it got it never miss treated nothing like that its a gem,

i think its hydraulic lifter issue failing on rear intake rockers .....but im not 100%

want let me uploads pics to big for server

anybody had this issue befor ?
anybody got some genuine information that might help please comment let me know what use think cheers

Go down to supercheap and get some oil flush and give it a clean out might just have build up sludge in the oil journals restricting the oil pressure up top. hope this helps mate
