it's a somewhat common misunderstanding that shimming or making the OP
relief valve piston Spring will raise oil pressure.
Sure ..it will raise the upper limit of Cold oil pressure.
it won't do a thing for hot idle oil pressure.
if it's not your OP sender coming on 'early' ...
it's bearing clearances are worn and large.
other than really restoring the bottom end to back where it belongs oil
clearance wise..
thicker oil is your main option.
they can run that way for years , not that I recommend it.
I own one 1.9 wbxr block that, once warm, oil light comes on any time
rpm's are below 1,500.
But it runs great and goes 70 mph no problem.
most people don't bother with 1.9 wbxr's anymore..
but if someone wants a block or long block for rebuilding, I have about
6 of those located in So. Oregon.
Don't want much for one either ( or all 6 , lol ).
