Where is a good place to get an acurate oil pressure reading on the 4 cyl motors? Also, what is the normal pressure?

 

if you are installing an oil pressure gauge it can go at the oil pressure sender on the back of the block or you can get a sandwich adapter that goes between the oil fiter and the block. my autometer piece of crap reads between 40-60psi at idle on cold startup and about engine RPMS/100 while cruising warm, i.e. 3000rpms = about 30 psi.
