hey guys here is a real crappy pic of the back of my b16a motor. What is the threaded hole circled in the picture for ?

 

Hey you stole my chop!

 

haha, thanks for the help on that jason

 

up

 

Nobody knows

 

i guess no one does

 

From the picture it looks to me like the oil passage block off from the head. Your suppose to have a copper plug in there if you dont then oils gonna leak out like crazy and you will have no oil pressure. hopefully this helped. lates

 

thanks man.

 

Yea, I have to agree with Scott said because I don't know of anything else back there... That hole just looks soooo small, about what diameter is it?

 

I will get better pics of it. the flash messed up the way it looks. there is another one by the cam gear side that is about the same size. I will take pics of both and put them up tonight for yall. thanks

 

on my motor thats where my oil temp gauge went into so just an oil passage. looks like it needs a plug.

 

yeah, not suprised. i bought the head straight out of a head shop. probly just left the holes unplugged for the guy so he could put temp gauge in.

 

Or that head was used on ls/vtec or cr/vtec motor. Alot of people use that to run the oil line for to the stock oil sensor.
