Google 'Nissan precat failure' or 'Nissan excessive oil consumption'. Going to guess your cylinder compressions are all south of 150, and if you drop the pre cat you'll find the ceramic catalyst material in pieces or generally MIA. If this is the case, the engine is terminal and you can look at a transplant, possibly with a JDM used engine, or just go buy another car and leave Nissan in your 'catalytic dust'.

The cat looked fine when i removed it but i did just buy this car and opted to try a complete oil change this morning. the previous owner had taken it to jiffy lube and i wonder if the oil the used was really cheap.
