Timing Help with pics

1. What piston should I put the motor on for TDC on the compression stroke?
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?

The set up:
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

hmmm start off by replacing the tensioner and spring.everything else looks "lined up". i have to check what the marks mean on the crank pulley. i dont want to give u an estimation and be wrong.

Alright, to start things off you need to remove the timing belt covers so you can see the tensioner and find out what the problem with that is.

You need the number one piston to be at TDC compression stroke (number one piston is the one on the distributor side)

Can't take my word on this next part because I've been working with the B18B1. The one white mark on the right side of the three is the one that needs to be lined up with the tab.

The cams might have a 5 mm hole right behind the gear to line them up. (B18B1 does)

number 1 piston is on timing belt side.

they have holes on the vtec head too.

its hard to explain how to get the timing belt tension correct. you have to have the belt get slack from the intake cam side, and then man-handle it over to the exhaust cam to get them to line up without the excessive slack.

I would put a new belt in also, cheap insurance. When you're setting the cam timing, use the single notch on the crank. The other 3 are for setting ignition timing.

My bad, you're right. I always get it mixed up because it sits sideways.

thanks guys... I fixed it sat..

haha no problem

cool what was the problem?

Yea, the lines on the cams should be straight across each other now with the new tensioner. Good to hear its fixed.
