Crankcase Breather Hose

I did the same w/ mine after hearing something like $110 for the hose
and none were available in the US at the time. My mechanic friend has
said, whatever you want to do is fine but the heater hose won't hold
near as long in his experience.  Some folks put a spring inside the hose
to prevent it from collapsing.

Hi Dan,

I just replace the breather hose on my 200q20v by making my own
replacement hose.  I used some formed radiator hoses from Autozone,
copper fittings, and hose clamps.  I reused the spark arrestor, and
things seem to be working well.  I just took the pieces of my old hose
behind the counter at Autozone, with their permission and browsed their
hose inventory.

I'm going to do the same thing on my 4kstq donor 3B motor as well.  I'll
see if I can't get some pics and part numbers together for the record.
It should be easy because the motor is loose on a cradle.

One of the radiator hoses I got has a taper that goes almost exactly
from the size of the breather port on the block to the smaller diameter
of the next section of hose.  The hoses were cheap too at like $5 each
or so, with two of them required.

I did have to reuse the end of the old hose because I didn't have the
right size replacement, but I have since located a piece of hose that I
intend to replace that end with.  There are three diameters in my
creation.  My creation!  Wierd science! =)  I was just reminded of that

Since this was just mentioned, my 91 200tq breather hose also has a hole
in it where it has rubbed on the coolant line for some time. Scott and
Rod said they weren't able to get only item. However, when
I've called a few dealers, they can't seem to find the part on the
computer at all.

Anyone know the part# for the breather hose?

Also, there was some talk about repairing the hose. I haven't found any
write-up's on this though. Any BTDT?
