In a previous message: ------ #4. Last, Last thing: if you suspect that the engine is wornout, which it shouldn't be at 120K, do a compression test, or have one done. This or the more revealing leakdown test will tell you the condition of your rings and pistons/cylinders. ----- What a leakdown test? Detailed info appreciated a bunch.. I'm shopping for an AWD ... thanks guys... Ash
