I had a slight ticking sound in my engine a while ago and decided to adjust my valve lashes. I had no issues adjusting them, but when I put everything back in place I noticed a knocking noise coming from then engine, and it smells like its burning oil, my spark plugs are all black as well.
I dont know what might have caused the knocking sound, as it wasn't there before. Could it be a collapsed lifter or a bad stem seal?
I'll attach a video of the engine running, you can hear the knocking pretty clearly.
This thing is driving me nuts.. I try to fix one problem and end up with 10 new ones.
