I was wondering if any of you have ever replaced an engine on your Catera. I just bought a Catera which was involved in a "light" flood. I am not sure how light it was, but all the lights, and electronic componenets work properly (brakes, dash, cd player, windows, door locks.... etc). The problem is that the oil pan is busted and there are engine parts in the oil pan. This is probably due to the car sucking in water through the air intake. My question is how hard is it to change the engine on a Catera. The Catera that I just bought is a 2000 Sport Catera, and has 58,000 miles on it. I bought it for the price of $3,500, and I found an engine with 25,0000 miles for $900. I am not sure if thats it as far as expences go, but sure hope so. If anybody has any suggestion or has done this in the past... please help me out.
