Default Timing belt loose with pics..WTD?

Timing Help with pics

1. What piston should I put the motor on for TDC?
2. Do the cam gears look lined up right?
3. Why does the crank pulley marks not line up with the timing pointer on the timing cover? Also there are 3 marks on the crank pulley. What mark should line up with the timing pointer on the timing cover?
4. I know the tensioner is loose or broken so there is a lot of timing belt slop and it is making a lot of noise.
5. Compression test done 250psi plus, on all 4 cylinders.
6. If the cam gears are lined up why is the crank not lined up with the timing cover?
7. The set up:
8. B18c1 bottom end
GSR crank and rods
CTR .25 over pistons (PCT)
ARP head studs
ITR water pump
B16A oil pump
NEW tensioner
DC sports 4-1 header

HEAD:
B16A head, ported and polished, 5 angle valve job
ITR cams
ITR valve springs and retainers
ITR injectors
B16 intake

i believe ur using the wrong tdc mark on the crank pulley. when setting tdc the pointer on the crank is all by itself. not the middle 1 in the group of 3.

the 3 marks in a row are used to set timing advance and retard on the distributor

when on that mark the slashs on the cam gears should point at each other and be inline with the mark on the rear cover. there should be marks on the outside edges of the cam gears also to, that lineup with the outside edges of the top of the head. use something flat to verify in line on outside edge.

what you could also do to check yourself while the valve cover is off is, put the crank at TDC and feel your rocker arms both intake and exhaust on cylinder number one, if there is play and the cam gears line up right your timed right. idk just an idea.

your bottom end isnt lined up(at tdc cylinder one and four will be a the top of the cylinder. tdc on the head is the lobes facing in opposite directions front and back). also it looks like you not tensioning the belt properly. you have to tighten the tensioner, at tdc, then rotate the engine 3 teeth counterclockwise, then loosen and retighten the tension to 35ftlbs.
