hi

 

my oil pressure is 45 psi and only 22 hot .... so not very good :(

 

i 've change my oil pump ( and the pick up ) ... nothing change

 

i was thinking about main bearing failure ?! what do you think ?

 

is it possbile to change main bearing without put out the crankshaft?

 

thanks

is that idle or driving down the road? if those are at idle that's really good for a small block ford. the general rule is there should be 10 PSI for every 1,000 rpm. at idle for a small ford is generally good at 10-15 psi.

Yep 15 to 20 at an idle sounds good to me 40 when your driving.
