oil filter plate 340
I added another 4 holes to mine. The plate was leaking and I needed to pull it off anyway to fix. I'd read the restrictive 4 hole design didn't help with leaks due to the high pressure it created in that area. The aftermarket/later plates also had more holes for improved flow.
The plate no longer leaks (I run a thin smear of rtv around the outside to be sure),.oil pressure is unchanged, no negatives that I can report from having the extra holes.
