In todays video I take you through why my Gen 4 LS LFA 6.0L Aluminum block engine had low oil pressure. This may apply to your aluminum or iron block engine. The melling 10295 oil pump was taken out and replaced with the 10355. I also added a new oil pump pickup tube o ring for good measure. My original o ring and pump were in good shape, so heres the fix, a high volume pump
