[QUOTE="oldmodman, post: 14253396, member: 10303"] When I got my Cobra in 2002 I was worried about the oil starvation problem too. And i had a few choices. Since I was planning on keeping the stock engine stock, while planning the "bulletproof" new engine build I really studied oiling problems and fixes. My simple and relatively easy fix for the completely stock engine was to run an Accusump as a bandaid fix for the problem. It will "take over" when a low oil pressure or volume event occurs and supply oil to the engine for a few seconds while the oil system recovers and covers the oil pick up again. Plus it can be set up as a pre oiler for the engine to prevent wear on cold starts. Or as a turbo oiler after shut down (if you happen to have a turbo). But for the next engine I will be getting a deep sump pan with a deep pick-up, doors to keep the oil at the pick up, oil drain back tubes (from Livernois) to make the oil drain back from the heads faster, and a Melling High Volume Oil Pump as a helper. I have actually considered, and priced out, a three stage external oil pump and scavenge system including an engine vacuum system. It was going to cost more than the entire engine, so that wasn't going to happen. Even if it was the coolest looking thing you can imagine. But as to your problem. Did you carefully inspect the oil pan and cut open the filter to look for metal garbage? If you did and didn't find any you are most likely going to get many, many miles out of your engine after you replace just the one scored bearing. It is absolutely possible that a piece of "crap" that had been hiding in the oil passages since the engine was built just suddenly came loose and made it's way to that one rod bearing and caused the damage. That is something that I HAVE seen before. We could not explain it, it just happened. [/QUOTE]
