so i finished building my b16 with low compression pistons did a compression test and got the following
180, 180, 165, 180

im kind of concerned for the cylinder that gave me 165 is being 15 off a big big deal or can i go ahead and tune the car like that

 

I would be concerned also. It could be your rings are lined-up. I would take that piston out and re-ring it.

 

before napalming the car,
do a leak down test and see where it is coming from, it could be as simple as a tight valve.

 

any more suggestions

 

leakdown test will tell you if its going through the rings, out the head gasket, valves etc

 

is the engine warm? broken in? WOT when cranking?

If no to any of the three, that could be ur problem.

 

you are supposed to be at WOT when crankin the motor ?
