1986 1st Supra Running Poorly

[dlfred]

I am checking the cam timing and I remember reading somewhere that you can look inside the oil filler cap and see the cam lobe pointing upward. I believe that the guys who did the BHG made white marks and a L or R on the cam gears. The issue I am having is that when I line up the painted lines and the crank is on 0, I can't see the upward pointing lobe. The look more closely and see stamped marks at 6 oclock. So my concern here is that somehow the guys have the cams 180 out. I don't even think it would run. I rotated the crank 360 and the lobe still cannot be seen. The car has been running OK just a idle issue.

So here it is.

1) Does anyone know about the looking at the intake cam and seeing the lobe when piston 1 is at TDC?

2) What is the deal with the marks on the cam gear? Painted vs Stamped?
