Hi Paul,
 Thanks for the analysis on the oil gallery size.

Wouldn't

the larger

 -10 hose have lower pressure loses than -8 hose?

Is it enough to

 matter?

Paul and group,
The Oil line size is not a big deal unless you have a system

that

could require

full flow. That woouldn't be common in a semi-closed loop

system

like

our engines.

The biggest problem with different sized lines is the area

where

the

line steps up

or down. The step area can cause cavitation at high flow, and

foaming

of the fluid.

Sometimes the diameter difference camn be used to your

advantage

like

in a cooler

where you want slower flow for heat transfer. Bill Jepson

Speaking of stepping down the usual dash ten used for oil

cooler

plumbing

steps down from .5 inch ID to .4 inch ID. That cannot help the

flow

:)

I think I am going to dash 8 everywhere. Dash 8 is a better

match

with

the 10 mm oil passages in the engine. Further more it is easier

to

route

dash 8.

The only reason I used -10 was because Mazdatrix sells the

metric to

AN

in that size. Is there a source for metric to AN-8 adaptors?

Yes I think Deering Industries can fix you right up.

You will need the dia and pitch of the threads in the oil cooler

and

the block. There are three big ones and one smaller one. The big

one

looks like 18 mm 1.5 mm thread pitch.
The smaller one looks like 16 mm dia. by 1.5 mm thread pitch.
I am not sure which one goes where right at the moment.
I'll check.

OK I checked. One 18 mm goes in the back end housing. The
16 mm screws into the aluminum front cover oil outlet
from the pump. The other two 18 mm must screw into the oil cooler.

Hi everyone,

does Deering Industries have a website? Googling I couldn't find any
specific site, just a lot of mentioning them!

Nope. They are kind of out of the dark ages one that.

Paul,
I found a lot of an/metric adaptors at Parker Hanaflin (sp??) shops that
make up hydraulic hoses. They can get them for you if they don't have
them in that shop, they said (2 years ago) that they bought a line
making those adaptors. Look in the yellow pages. I used those adaptors
on my tt 13B oil coolers (fd type) to change to an lines.

Thanks for the tip. I'll look into it.
Did you use dash 10 on your oil lines Marc or dash 8?
