Yep - the #1 rerason for premature failures - that I can guess, is starting the engine off the bat without priming the oil first, good and proper. Like I said to Todars, and like I did on my 3L build - I take off the connection to the coil pack once I'm ready to go, and then crank the car over for a good 30secs. This allows the oil pump to get oil every where without any loads form the engine running. THEN you reconnect the coil pack and start it and let the thing idle to it gets warm. Without doing this you are basically putting combustion loads on the mains and rod bearings before there is enough time to get oil to them. This gouges the bearings and then they quickl (50-100miles) fail after that.
