I was needing to top it off every morning, and on long days, before I went home. On my last trip before replacing head gaskets, I went thru almost 2 gallons in 5 or 6 miles!

Let me know if I can be of any help. I do have a set of intake gaskets that are used, but only for 3 days max. If you find it's only the intake, you can have them.
