I'm in the last stages of putting my motor together, what is this hole for? I have it currnetly sealed off but I kinda need to know. Thanks.

 

you can use it for PCV setup.

 

what block is that ive never noticed a "hole" there. theres a hole on the right side of the oil filter but that for ur oil rez. (the black box).

 

It opens up to the crankcase I believe. I know the big hole to the right of the oil filter connection does. What you have there might be a plug that opens up to the water jacket. Sometimes this thing is called a "freeze plug" and removed when installing block heaters in the northern states.

 

looking closer, I don't think it's a freeze plug. I think it opens to the crank case just like the hole to the right. Just leave it plugged.

Here's my B16A. It's plugged there too. Just leave it alone.

 

Sweet thanks. and its a b20 dart block

 

a B is a B. plugs and holes all do the same thing. PLug it with one of these big *** plugs and call it a day.

 

The plug on the top right if for the factory oil cooler option. The one on the bottom left is a clean out plug.

Dart block -fap fap fap fap-.

 

I believe the Dart block uses a different plug than a Honda block, if I remember right I had to use a 3/4" NPT fitting on mine, but check the threads to be sure because I could be hallucinating again. I used both those holes for crankcase ventilation.

I know. I had that thing circled from a previous question, and that pic was the only one I had online at the time.
