All,
I am looking to change the oil pump as a way to up my oil pressure. I understand that this may well not help, but having a new oil pump around is OK. With that in mind, what are my options? I will pull the motor but hope to not split the case. Is this even possible? Which pump? Thanks Peter |

That pump is looking pretty promising.
In the pump body - is there a noticeable “step” where one gear has worn lower than the other or is this little area just a lighting & photo abominably. Disregard the milled oval slot and that little triangular point from machining. I’m asking about the area where the two circular gear wear patterns overlap.  Post photo of the other side of the end plate like this view so we can see where the idler shaft is at and whether it has been pushed out toward the cam. This perspective  |
