Breather system (5 port)
Just sorting the breather system out and need a little advice regarding the port that goes from the separator to the turbo side of the block instead of the rocker cover.
I have a -10 fitting on the separator fitted with a -10 to -8 reducer down to the block - this is where i need help what is the thread size of the hole in the block turbo side?

i would'nt reduce the port to -8, i would keep it at -10.
use the reducer for the oil return to the sump, so you will need a -8 on your sump.
thats how i had it i still have the fitting on my engine but not sure what the thread size is but i can measure it for you.

3/8" BSP is the thread size on the exhaust side of the block, under the water drain bolt (which is the same thread size too).
As said keep the hose -10 on that side, so you need a 3/8" bsp to -10 jic adapter.

i think 3/8"bsp is a bit small mate, it measures 16.9mm or 0.66"
one of ebay says its 5/8"

That size on the fitting mate is 5/8 ID of the hose

Justin what you have described there is not using the ex side block return at all and plumbing straight to the sump which if i were doing that i would keep it at -10 from separator to sump but i was going to go from separator to ex side of the block i didn't think i could redue straight from -10 to -3 are your saying fit 2 of the ports into the sump?

no mate you have misunderstood me.
your drawing is correct how to pipe the breather system up, but dont use the reducer on the seperator, keep it at -10. so you need an -10 fitting for the block not a -8 how you had it

So this is the fitting (AN-10) 7/8 JIC x 3/8 NPT
http://www.hosefit.co.uk/catalog/pro...30f59c870b947b
Justin i'm going to run one of thos fitting from the exhaust side of the block (AN-10) 7/8 JIC x 3/8 NPT then run all 4x AN-10 and the 1x AN-12 from the separator.
Thats it sorted -
But just curious as to why you would run -8 on the return as opposed to -10 that is fitted already?

most people use -8 and i thought if you used your reducer you already had on the bottom of your seperator it would save you money on fittings & hose because -10 are more expensive.

Just had a mate text to say it NTP so i'll go with that - not sure regarding the size you used, whats the difference between 3/8 BSP & 3/8 NTP???
No probs mate i have some spare AN-10 stuff here and weld in fittings etc so will just go with -10 return
So this is it then
So this is it then

very little difference between npt and bspt,both tapered,
bsp is parallel,
i think its a tapered thread at that fitting below turbo,
unsure what thread it is tho
bsp/bspt means british standard pipe/british standard pipe tapered
npt means national pipe tapered(used to be more an american size maybe still is)

NPT is a tapered thread (National Pipe Thread Tapered Thread), used in the US. The fitting will "crush" into the thread to seal, and you'll need to use PTFE tape to make sure it doesn't leak, not ideal if you ever need to take the fitting out as you'll probably get bits of ptfe tape falling into your sump. A 3/8 NPT thread has 18 tpi (turns per inch)
BSP (British Standard Pipe Parallel) is not tapered (BSPT is tapered). A 3/8 bsp fitting is 19 turns per inch.
The thread in the block is not tapered, which is why i said it was 3/8 bsp.
Food for thought: The pinto engine was built by Ford Europe, not Ford USA...

I'm not saying a 3/8" npt adapter / plug won't fit because they will, but the thread in the block isn't tapered
Years ago my old GGR engine was supplied with an alloy adapter in this opening, when i rebuilt that engine i wanted to put a new one in as it had seen better days, I didn't know what size it was so I took it along to think auto in Isleworth so they could measure it and they measured that fitting as a 3/8" bsp, I would hope that a supplier and manufacturer of threaded adapters would know their stuff
