The timing chains on these things aren't difficult at all. The important thing is to double, triple, quadruple check that you're at TDC. From there it's virtually impossible to mess anything up.I'll admit I'm a little apprehensive about doing the timing chain and headgasket myself, it's little bit outside my comfort zone. I know it's not rocket science, I guess I'm just a little afraid I'll mess something up. I'm hoping if I take my time and label everything and do my research it should turn out fine. It's time to teach this old dog some new tricks, lol.
Just do the research, jump in and you'll be fine!
