hi

im planing to get rid of stock oil cooler as i have oil pressure issue ,i hope it will help

anyway does anyone nows the thread size of the bolt holding stock oil cooler - side that goes into engine

 

thanks for fast reply

im sure on 100% is not bearing or oil pump , its fresh built up

problem has started after i installed oil cooler and oil stat both by mocal
at idle when cold the pressure wont exceed 70psi ,when warm its dropping by another 10psi ,the oil stat is installed properly

to make it clear you are talking about this bolt, maybe not particular part number
