Because my first post got rather long, I started a new post. I am new
to Groups, so if there is a forum etiquette please let me know.

I have the Gold Volvo 740 GLE, 1987 I bought last week for $500. My
first post is here:

Here is where I am now, as I had just cleaned the Breather Box and had
the car idle VERY poorly and die out. I purchased an O-ring for the
Breather Box for 38 cents at the local mech. shop. This completed my
parts for the B-Box. Before testing this, I noticed during the
installation a wire unclipped from somewhere. I discovered I knocked
this off, and it bolted to the engine block, just above the B-Box. It
appeared to be part of the engine wire harness. Well, I had broken a
clip from the snap on adapter, so it was damaged. I unbolted the bolt
that secured what looked like a washer with two electrical prongs. I
had to solder the adapter with one prong still in it to the ring with
the other prong on it. After soldering the this I was able to bolt it
back onto the engine and I started the car.

Fired right up, idles nicely, sounds GREAT!  I let the car run 2-3
minutes and had no oil leaking. I was happy, but a test drive set the
oil to leaking again, so I fear I was too late in cleaning the breather
box. The prior owner let it go too long.

So, I am confident I cleaned the B-Box well, and will probably replace
it down the road to be sure. I'll change the seals knowing I think I
reduced pressure. What bothers me now are the exposed wires and
possibly bad connections in the wiring harness.

I read where I guy named Dave sells these for about $200. Any thoughts
on where to get a harness for a good price and exactly how much work is
involved swapping it out?

thanks!
