Contour Enthusiasts Group Archives Forums Modifications 3.0L Duratec Updated oil pan vs.... 3L heads

Yeah sounds odd doesn't it?

Anyhow from what I understand, the updated oil pan is needed because drainage from the heads may be too slow, and the baffles, help ensure a supply of oil to the pick up tube under hard right cornering.

Now do the 3L heads, suffer from the same drainage problems?

I can be waaaaaaaaayyyyyy off here, but I'm still curious.

If drainage isn't the issue, then what is the exact reason why oil isn't being fed to the pick up tube under hard right cornering?

If you are going to answer No to the first question, then please explain the second question.

They are 2 different fixes to semi similar problems. On the hybribd 3L's since we're blocking off return ports we don't get the same return volume that the 3L's have from the heads. The oil pan is mostly to help with oil going all to one side of the pan under side load. Both are oiling issues, but only slightly related in the fact that the more oil you get back to the pan, the less baffling it needs. Solution- use both 3L heads and the new pan.

Here's Mr. Haines take on it.

...not as deep as the stoc 3.0 Taurus pan....and just
has the baffles cut at the edge to help get the oil
back in the pickup area...if it were an oiling issue
re oil in heads etc it wouldn't take XXXthousand miles
for the lube to 'run dry'...you would have oil
strarvation on a new engine aswell....which most
dont....I dont buy the 'oil in heads'....'long
sweeping curves' idea.....the problem happens over a
period of time...a bad design for lube would be there
from zero miles.This is a component 'stress'
issue...and I know which component it is,from
measurements of torn down failed engines....most of
the oiling ideas are BS!...just think about it!


So in other words Clevite bearings are the answer to the problem. DMD and oil pan MIGHT extend the time that this occurs.

How does Mr. Haines explain my second failure: motor runs fine, goes through hard right hander, motor no longer runs fine? Oh, that's right, he called it 'BS'. I must be making it up.

He's telling me it's the bearing nips which are set by the engine builder. I wonder if my problem is that the engine sat too long and their wasn't sufficient lube on the bearings. Just a guess. The next engine will have prelube.

soooo... since i'm running full 3L....

i still pose a risk to this, but my risk is lower than if i was running the 2.5L heads with blocked off return holes.....

i "should" still get the new oil pan, but it wouldn't be needed as much as if i had the 2.5L heads.....

are thoses statements correct....

I'll stay out of the 3.0 heads and oil pan issue, but I do believe that the clevite 77 bearings are a wise choice. I'm certain that there would be less issues with the Duratec bearings if they had better bearings.

I have clevitte bearings... i'm just wondering, if i really need to spend more money on getting a new oil pan or not.....

i've already blown a motor, mind you it was because of a defective ford part, but I don't want to go down that road again.....
