cam gear arrow pointing to the side
So yesterday I was trying to line up the arrow to TDC but before I'm guessing when I installed the head the cam gear moved and then tried turning the cam gear by hand to have the arrow pointing up would the head shot. Sorry if this doesn't make sense
Safest thing to do. If the crank is at TDC(arrow/notch lined up on crank) rotate the crank 90°. This should bring all the pistons down to the same level and you will be able to freely rotate the camshaft without the valves hitting the pistons.
If you feel resistance in turning either, STOP. Forcing may bend a valve.
Slowly rotate the camshaft to UP position. Then slowly rotate the crank to TDC.

Crank is a flat crank, ala...

1 and 4 are at TDC when 2 and 3 are at BDC. Rotate crank 90° and all the pistons will be midway in the cylinders. The camshaft/valves should be free to spin with no issues, but it is always best to be cautious incase there is a problem with something.
After putting the camshaft to UP rotate the crank back 90° to TDC to get the belts timed.

Ok so remove the head rotate the crankshaft 90degrees and after I'm done then I can move the cam then would I inspect the head again

@ Mad mike what should I do cause the arrow is pointing down on the cam and im not able to move the crank I feel play on the crank but I cant fully turn the crank
I really don't wanna use force by hand and end up valves hitting the pistons and messing up the vehicle cause I got alot of stuff going on personal things and I need to make this car drivable with having any more problems let me know asap
Where is the crank in relation to TDC? WHen the cam is pointing up or down the crank will be at TDC. Cam spins half speed of crank. If the crank is at TDC when the cam is 180° out(UP facing upside down) the timing is still fine.
Im in the same boat..i lined up my crank and had the UP facing up but the rotor is facing #4..dont know how this happened..i tried your 90 degrees out on the crank but when i try to turn the cam i fell resistance so i stopped..runs ruff..puff puff sound out of tailpipe..erratic..no power..takes for ever to get to speed.. Bent valve im thinking
F22b2..i bought it from someone that did a tb change and sold it after..this guy didn't know anything..didn't put a piece of wood under the oil pan..stripped numerous bolts..buy somehow got the cam gear 180 off..the crank it lined up and the Up is up but the rotor faces the firewall..also it runs crappy..i just battled the tb gear..stuck woodruff key. Noq i can move forward..should i still attempt your 90 degree on the crank without the plugs in..thanks
One of the things with the B2 vs B1, or maybe its a TEC vs Hitachi thing, the firing order on the distributor cap is 180° out between them. 1 is 4, 3 is 2.
If you are looking at a generic DIY book they may show the wrong distributor or tower numbering than what is actual. 'A' or 'A1' is #1,
Also if the internal coil Hitachi B1 distributor was installed on the B2 then the numbering of the towers would be wrong for the B2. I would verify this before trying to 'fix' anything.

If the cam is 180° out I don't think the engine would run.
Verify that the engine itself does not have bent valves.
Verify compression is good. Leak down test may be the best way.
