Ok so lets pick your brains. I bought a 99 accord to fix and sell. Ended up being a burned exhaust valve. Head sent out, replaced valve, all new valve seals, and machined. Car ran awesome. 1000 miles later cam broke where the pulley mounts on the end of the cam. Replaced the cam and runs great no issues. another 1500 miles later after changing oil(honda oil and filter) car throw code p1259. Checked oil and its just over 3 qts low. Dont ever see smoke out of the exhaust when driving behind it or smell it. Where is the oil going? What is my fix here? Would you think it was the rings? or something else to check first? Thanks guys!

 

Do a compression check. If the engine bay is dirty, clean it and look for fresh oil leaks.
