...BUT if it were oil starvation that caused spun bearings 'due to design' then an engine would have it 'from new'....This is a progressive thing...most engines spin rod ends between 65-85,000 miles...if it had 'bad lube'/bad pan/oil retained in heads etc etc it would have been like that FROM NEW!....It is not my opinion that the spun bearings are caused by lube at all....Using all the pan/pickup/dipstick & tube/windage baffle 'as is' on a 3.0 converion is the best way to go.....but again the oil issue would be there 'from new'.....


If it were a foreign object problem it would be main bearings failing, Not rod bearings. Even if it were to be a rod bearing it would be #1 or possibly #2.

However the most common failure BY FAR is a rod bearing and it's #6. The first to lose lubrication when oil pressure drops.

My 2.5L engine had NO sand material in it and the typical signs of lubrication failure at Rod Bearing #6.
Most pictures I have collected show these exact same symptoms of oil starvation.
All the information I collected from the several race teams stated it was lubrication failure as well. Hence why the Accusump cured their problems.

Now I'm not saying there might be a chance for Zircon contamination in a select time frame on a small percentage of possible blocks but the MAIN issue for the 2.5L is an oiling issue. 'nuff said

...and sorry for being so rude Bob.
