I got a B16A block that I would like to replace my current B16A2 with. The B16A looks a little different than the A2. What's the 2 oil line coming out where the oil filter bolts to go? The A2 block does not have those two prongs. What do I need to do to get it to work on my B16A2 head? One of my cylinder wall has deep scuffs on the walls and that's why I need to replace the block. Here's a pic of what I'm talking about. Any help is appreciated. Thanks

 

oil cooler

 

jdm motors came with an oil cooler. those two lines coming off of it are coolant lines. on mine, they loop through that coolant bar that goes from your water pump to your thermo housing. your usdm coolant bar will not have any lines coming off of it for your cooler though since usdm motors didn't come with that. at least thats how my b18c was.

 

obd1 b18c1 had oil cooler

 

Just loop the lines and you'll be fine.

 

Thanks, that helps.
