Hey I've been noticing that everyone's LS/VTEC oil line kits all come with NPT fittings to go into the oil pressure sender location and where it attaches to the cylinder head oil supply. I'm virtually positive both these fittings should be BPST - so does this actually work for everyone or do you eventually have leakage problems?

Thanks in advance

 

it goes in a bit tight, but doesnt leak. its fine

 

The oil line off the block is a 1/8 BSP ..
you need an adaptor to NPT
the thread pitch is different..

 

i just thread it in. no problems. 1/8 BSP and NPT are similar enough.
