Hey everyone, Im going to do an ls vtec soon and I need to know what size fitting is needed behind the head for the oil line. I am planning on using a -6AN oil line so I know i need -6AN on one side but what size thread is needed for the head? I am planning to tap oil from the oil pressure sensor. That would be 1/4 NPT pipe thread right?

Dose it matter how big the oil line is? If i doesnt should I go smaller, maybe -4AN?

Please help me out, this is my first ls vtec build.

 

search, lazy ***

 

You will need a 3/8npt to -6 for the head and a 1/8"bspt oil distribution block with a 1/8npt to -6 adapter. We have a kit for $70 shipped which includes all of this plus the 2 dowel pins, and the assembled line.

 

Obey the above poster, save yourself the hassle of parts collection tedium.

 

Haha ok ill get the kit from B&R fittings. Im not lazy, just lost. Is it better to tap from the block or use oil sandwhich plate? does it even matter?

 

Are those GE dowel pins?

 

No their not, the place that does all of our machine work makes them.
