I haven't hit any dealers or auto parts stores, just what I could find on the net which was really only the belt. I think I might have seen the timing gear cover which is just a plastic molding but mine is ok. I saw rockers cheap on eBay but I can't confirm they are the correct ones without either buying them or a parts list.
The belt and injector pump seal showed up yesterday so I installed the seal and put the pump back on the engine, installed the cam, rockers, and associated timing pulleys. I set the valve clearance at 0.012" on all valves and later on found out they need to be set at around 0.010" on the intake and 0.018" on the exhaust so I'll need to go back and redo that. Looks like the head bolts should have been torqued to 75 ft*lbs but I'm not going back and loosening them now. Rocker arms should be 18 ft*lbs. but I was pushing 30 and that felt a bit much at the time so backed it to 25.
I had trouble with the belt since the crankshaft and injector pump pulleys were clearly marked on the engine in the 12 o'clock position but I couldn't find a mark for the camshaft pulley on the engine. I made the assumption it should line up with the split line for the valve cover by noting where the cam lobes were relative to the #1 piston, but I ended up picking the wrong side. The cam pulley mark should be in the 3 o'clock position but I initially set it in the 9 o'clock position. The good news with this mistake is there were no interference issues with the pistons so I could successfully test the rocker cycling, at least when rotated by hand. I eventually found a diagram on the net that showed the correct arrangement. Without the diagram, I would have had to check and see when the injector pump was injecting on the #1 cylinder as I didn't know if the pulley timing is set up for #1 cylinder firing on TDC or for it entering the intake stroke.
I was going to try to finish up tonight but it's raining. I should be able to test before the weekend is over and I'll get a video of it trying to start up the first time and post it.
