2006 subaru forester   If my Timing marks a line but my #1 piston is bottomed out then #1 is up and marks don't a line has it jumped time

Timing marks go by the hash marks on the cam pulleys, not the arrows.

 

The mark on the flywheel III represents all of the pistons are at the center of their stroke, not  TDC

 

TDC marks are not used for timing belt alignment. Only for a timing light.

The arrows are for valve addjustment

what they said - never the arrows (triangles)

 

the crank sprocket should have a hash mark on a 'tab' at the back that should be at 12 o'clock position.( the arrow will probably be at 3 o'clock but, could be 9 - not sure).

 

 

kinda like this (your engine may look a little different);

 

When at proper time the crank arrow will be at 3 o'clock. Cam arrows will be at 1:30.

Do not use arrows for timing, too difficult to hold the cams still. Use has marks on cams and the groove on the back of the crank sprocket as pictured above. Hash marks and groove should point straight up for proper timing.

 

If using the white marks on the belt, they will not line up again after rotating the engine. You must use hash marks to determine if timing is off.

And confirm marks are painted on the belt in right spot they dont always get it right
