I have been a member of CEG for only a few months. Already I have heard about two or three people who have spun a bearing. My question is there any way i can prevent this from happening to me ? ?

Read up on oil starvation in the duratec forums. Basically the ways people try to prevent this is running 6.5 or 7 quarts of oil, not reving the engine in sweeping right hand turns, or various other precautions. The best way to prevent this is installing an accusump, that way if the oil pressure becomes dangerous, the accusump will dump its load and save your bearings.

accusump is the name of the product ? Is it expensive ?

I suppose expensive is a relative term. BAT has a kit for around $300 IIRC. Do a google search for moroso or accusump or oil accumulator and you should come up with some stuff

Keep in mind that NONE of these methods are considered fail-safes. Also remember that NONE of the methods are able to do the job on their own. It would take the combination of two or more of these suggestions, and even then it is still not impossible.
This is simply a flaw in the design of the heads, and can't be completely avoided. Only driving style combined with 2 or even all 3 of these methods will prove fruitful.
oil accumulator... accusump/moroso brand
revs lowered on sweeping righthand turns. (remember that this is not a magic number.. length of time in the turn, and G forces while turning will affect the "limit" of the revs you can reach. a steady, easy right hander may very well be fine at 3500, or 4000.. but add more G's to that and now that 3500 should be lowered to 1500 or 1800.. all dynamic..
Running 6.5 (or so.. some run 6.. others run as much as 7.. research to find your level) of oil.. 5W-30

Why isn't the Accusump fail-safe on its own ?
If the issue is oil, then accusump fixes it, right ?
Has anybody with an oil accumulator/accusmp spun a bearing or nuked the engine yet ?

Accu-sump buys you more time in a hard turn before you run out of oil. If you stay in it long enough, even it may not be enough.
It may also help to install better rod bearings. Clevite 77 seems to be the higher grade bearing of choice. Main bearings are not a problem.
I'm an agressive driver, but with a bit of common sense, I have avoided the problem without any modifications. I avoid hard acceleration or high revs on sweeping right hand turns (freeway on ramps) and use 6 quarts when I change oil. I have 205,000 miles on it and it still runs strong.

I think this problem is very over-played for street driving. Remember, some of the people on here race these Contours on tracks...and on streets. A few failures at low mileage does not mean they all will. This isn't like the SHO cam sprockets because those happen regardless of how you drive it. You crank the motor up, and it's already a ticking time bomb. Yes, the oiling system is flawed, but for a normal street driver, it's must easier to avoid.
Plus, a 2.5 Duratec is a lot cheaper to replace (Or upgrade to a 3.0) than it is to replace one of those 3.4 V-8 SHO motors.

Still can't believe they had a 3.4 v8

I've started to make sure that my oil is 2-4cm's above the fill dot as people have said ...
Either way, I'm still going to move my battery to the trunk and try and get a 2qt accusump in there ... 2qt's should be a lot extra. Maybe a DMD too just in case.
