Contour Enthusiasts Group Archives Forums Modifications Duratec Maintenance overfilling the 2.5 Duratec

Im with Ray on that one. All the extra oil should be in the accum. unless there is a drop in pressure. If it isnt, there may be something wrong.

I have the middle EPC valve which is set for 35-40 psi

At idle and most of the way towards 2k, the oil pressure in the engine is below 35 psi

I was doing 6.5 and then added the oil filter relocation. With that big ol filter im running close to 7 I think

I've been running 6 to almost 7, depending on use. I'll run 7 at the track, 6.5 autocrossing, and 6 in the winter. I've never noticed any difference in anything.

This is the email I got a while back

as far as the accusump opening and closing often, it will not
harm the valve, thats what it is made to do, as far as it opening,
when you pull up to a stop light or at idle it shouldnt be a problem
as the engine should only take the oil in from the accusump as it is
needed, if it is not beeing "pulled in" by the engine it shouldnt
really push to much in
