not sure on the pcv valve, but I did almost everything else, rebuilt head, replaced head gaskets, water pump, timing belt, what else do I need to do, OIL is Burning up!!!

If I drive from NY to Boston, my oil light goes on and is empty, I have taken to lexus dealer and to other local experts, no one can tell me why it burns off, there is no drip and no leaks, I just replaced the seals and caps (almost 3k of work) I should of replaced the whole motor at that point. Why does this happen how do we fix it. I have used all kinds of oil, high miliage and top synthetics but still I have to add oil almost weekly -HELP
