Oil cross over or not I need help please.
Also how far up the rear gallery from the oil pump does that plug sit? I have 1 5/8" from the bottom of the block.
Cheers
It stops when it hits a step in the bore size
I also drilled out the feed lines I forget how big,(perhaps 9/16 or even larger,I forget), to and from the filter, plus from the pump and "ported" all the turns smooth, including inside the pump. I doubled up the filter base plate as an anti-balloon measure, and drilled 4 additional holes thru both. I did not use the 90* adapter. Then drilled out the filter retaining fitting. And finally used a larger than stock supply pick-up. I think there is a sticky in the tech section.
I didn't do the X-over cuz I'm a streeter and seldom is the engine working hard.
In your case, I would do it,for the protection it offers. It's cheap,effective. and not hard, and it might save you thousands of dollars; you'll feel it on the driver tool during installation. Shine a lite in there and poke a rod (or the shank of the drillbit you used to enlarge the passage) in from the filter pad; you will see the rod at the end of the passage. I tried to port that corner too.
