It is not uncommon for a rebuilt engine to go through a couple of quarts of oil per 1000 miles. If chrome rings were used then they might not have sealed. Burning one quart of oil every 500 miles will not be decidedly noticeable. After 2000 miles it may be fine now. Check the engines condition with a leak-down test but I doubt you will find anything wrong. Change the oil and filter, as you should have after the first 1000 miles, and then monitor the oil at 500 mile intervals to see if you are still losing oil. While checking your oil watch for obvious leaks at the filter, drain plug and rear of the pan. Some leaks only happen while the engine is running so if you had a minor leak it may not have shown up on the floor of your garage. It might be spread out over miles of road that you drive.
rebuilt, rewired, modified for slalom and hill climb
No racing - just a fun car built by and for me.
