Knocking noise

Hey y’all, I’ve made a post about this before but I’m confused, my Fzj80 has been making this noise on cold start for a few months now. Once the car is warm the noise goes away but on cold start or the first few ministers of driving it likes to make this noise. The weird part is it has good compression. I dumped some of that motor lubricant oil in, the really thick shit to quite down motors, and that helped but only for a short period of time. Any advice thanks in advance
