I have a 2003 Kia Sedona EX with 103k miles on it. It is currently in the shop (KIA Dealership) and I'm being told that I have metal flakes in my oil and excessive sludge in my oil passages. This is causing my oil pressure to come in at 15 PSI instead of the specified 93 PSI. My mechanic has recommended a new engine.
I have only had the vehicle for 9 months and have done regular oil changes in that time. After researching this issue I wanted to see what you suggest.
Is there any hope of cleaning out the sludge? If yes, what do you recommend?
Can I do successive short-mile oil changes?
Can I use SeaFoam or some other product to clear it?
Did I just happen to buy a car that hadn't been taken care of very well and now I really do need a new engine?
UPDATE: I posted below to answer questions. Please let me know if you have any other suggestions.
Update 2: I've already replaced in the last 6 months of the 9 months I've had it:
Tires (Less than 10k miles on them)
Front & Rear brakes (whole thing)
Water Pump/Timing Belt/Serpentine/etc
Catalytic Converters - both fronts and the rear (just last week!!!)
Update 3: You can read all the details in my post at the bottom, but long story short I got a 2nd opinion from an independent mechanic who told me he can't find any metal flakes in the oil or all this sludge in the engine.
