This is a very common problem with the LS1s, it is both a problem with the PCV system and with the rings on the engine. If you visit both www.ls1.com and www.ls1tech.com and do a search there on oil consumption, you'll find literally hundreds of posts on the subject. Here are some recent links on the PCV issue and how to fix it though: http://www.ls1tech.com/ubb/ultimatebb.php?ubb=get_topic;f=24;t=003290 http://www.ls1tech.com/ubb/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=003372 http://www.ls1tech.com/ubb/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=001709 http://www.ls1tech.com/ubb/ultimatebb.php?ubb=get_topic;f=1;t=006488#000003 FWIW, I used to own a 98 Formula and had no oil burning problems at all in the 27k I had the car. Although it's new owner now has problems. Some of the oil burning has been attributed to driving style too, they say those that do light loads at higher rpms burn more oil (such as if you leave the tranny in a lower gear around town and rev at 3000rpm)
