Sorry to disagree but interferance engines have valves and pistons occupying the same space at different times. When the timing belt snaps or spins off, valves and pistons kiss. Goodbye engine. I went through two 3.0 liter engines since last year. You can get salvaged engines through 'scrap yards' Be sure you get a 2000 or newer production engine as they made some mod's to reduce timing belt problems. Have had latest engine in harsh sevice for 5 thousand k. No trouble so far.:D :D

Naah. The engines were designed by Opel in Germany, manufactured in Ellesmeer England at the GM Vauxhaul Plant. They called the engine an L81 for GM but in europe it's also known as the "x 30xe". I think. Now it's been reworked as the 3.2 liter LA3 for the new CTS. :yup:
