Ohoh,
my last reply is missing here, is it gone??
I installed a hard line between front and rear
oil pressure port using aluminium fittings like russel or aeroquip and aluminium tube.
See the new Engine picture in my gallery.
The pump is adjusted to 80 psi warm above idle, everything is fine now.
Thanks for all the support you guys gave to me.
A great forum............
