Worst enemy?

Ok so it’s a double overhead cam engine what’s the issue :drama:
The biggest issue is "Timing"....................................you have to choose the right time to take it apart and the right time to put it back together. So "Timing" is very important if you want the engine to work correctly. You must use special great care and "Timing" when you're installing the chains. So choose your correct assembly time, it can be day or night, it can be 2PM or 8PM as long your "Timing" is correct!!! So, to conclude...................No issues as long as you have the correct "Timing" when you assemble the engine!! :rofl:
