I am having trouble timing my 22r, 1987 mini truck. It was running great and replaced the plugs, adjusted the valves, checked the wireset, checked ignitor, etc... but when i time it, is is advanced 8 BTDC. It sounds great, but not timing right. I took it for a short drive and seems find. I did not drive too fast nor hit the skinny pedal to hard to test for knocking.
I adjusted the valves based on the timing marks on the pully being at zero mark.
The distributor is cranked as far as it can go clockwise so i can't get it back to 0. the timing on this truck/engine should be at 0 with vac advanced pinched off and 12 with the vac advanced hooked up. Distributor was not recently removed.
I checked my timing light against another unit and that is not the problem.
The vac advance seems to work right when I hook up vacuum to it.
Timing chain seems good. guides look ok, the tensioner as well (inspected from above). There is good tension on the left (pull) side of the chain.
One question, when i was adjusting the valves, at TDC, the dot on the timing chain cam gear is not quite all the way at the top. it is very very slightly to the left. Also, i noticed that the shiny link on the timing chain was about 6 links behind the TDC dot on cam gear. Should the shiny link always match up with the dot or is this only when you install the timing chain?
Also, there is a VAV that seems to make noise. This VAV i believe is part of AC system.
Thanks.
