Mine works great also and this leads me to a question for everyone since everyone has a differen't oponion not to cut in on your question but i have a high volume oil pump kit , pressure is about 90 on cold starts with 10w30 idle is 30 when engine temp is 185. I have seen several 109 blocks with stock oil pumps have distorted rod bearings from my and other oponions engine detonation. I have a 87 t type that seems to have an indestructable bottom end , while tuning and learning i went through 2 sets of wirelock head gaskets and melted 2 spark plugs when my walbro failed so i decided to freshen up the engine , to my surprise their was no wear to the bottom end , all bearings looked new , my question is did the high volume oil pump have anything to do with this or was it luck , i expected to see worn out and copper showing on the bearings but none , so give some oponions on this
