When I encountered this problem years ago , as I said before , the relief cover solved it . The relief spring in the case ( pulley end ) will stop the doghouse cooler blowing , although I have heard of other people having this problem ( personally I've never had the problem ) . But the case relief valve wont help the sudden pulse of thicker cold oil pressure at the filter , only 16" oil line distance from the pump . I put an Autometer oil pressure sender in a fitting at the oil filter bracket before , and the pressure at the filter bracket pinned the gauge past 150 psi easily .
x2 install it...
all OEM use pressure relief systems direct in/at the pump. And that system costs money so it is there for "some" reason!
With an 30mm /blue printed pump (driving in the cold months) I would always use a relief cover to keep the filter save for cold starts.
The pressure is caused by the oil flow and that is everytime the same, even when the regulator piston opens wide... The pressure drop over the filter is high especially when oil is thick.Keep that in mind.
I always use a MK2 Diesel oil filter (OC47 I think) which has a simple over pressure vent inside which bypasses the filter element.
Have fun!
