California98Civic, what 3 modifications would you say netted you your largest economy gain of all your mods.

*I admit I didn't read all 26 pages of this thread.

Thanks!

Oh yeah, and about your oil pan.

I have to assume you're running the D16Y7 engine, which has a stamped steel oil pan. I feel your pain about chiseling out all that old gasket.

If you feel it's leaking again I would HIGHLY recommend looking into a used Y8 or Y5 oil pan. It will bolt right on. I am not sure if you'll need the pickup tube with it or not. I would grab it if possible.

Another thing that is different is on the Y7 the transmission braces that wrap around the oil pan. Get them off the Y8/Y5 at the same time or just delete them. I am not convinced they server any structural purpose. I think they're only there for NVH.

Cast aluminium oil pan, COMPLETELY different gasket which is a 100% improvement over the Y7 setup.
