i search and did not find alot of usefull info

here is my ?

i have a euro/jdm D16A with a z6 oil pan what is correct dip stick i was told ALL sohc dip sticks are same length but i compared to my jdm d15b dip stick and it is longer than my z6

what one should i use it is a DD how ever it is a BUILT motor i want correct oil level/ pressure

 

I would say use the z6 dipstick as you are using a z6 oil pan...
