| Milodon Oil Pans |

Many have you have had input, or at least read my problems with low oil pressure with my 428. Worn main bearings due to oil starvation turned out to be the problem (as best as can be determined). With solid lifters (hyd lifter oil galleries blocked off) and restrictors in the heads, oil pump sucking air under hard acceleration and possibly during cold start also, appears to be the problem. The FE heads don't drain well either, as the head bolts partially obstruct the drainback holes. Milodon has an interesting looking wet sump, P/N 31650 which I am considering, but it says for use with a Melling M83HV vs the typical M57HV. I have a few questions for any of you out there who may have some experience with these parts.
1/ Anyone use this pan, and was it a success?
2/ Does anyone think it will be a significant improvement over my cast aluminum Tony Branda 6 qt plus filter T-Type pan (the Milodon is a 7 qt plus filter pan advertising extra baffles for violent turns, acceleration and de-acceleration)
3/ What is the difference between a M57HV and a M83HV? Does the pressure relief valve give the same max pressure for both pumps. Do both pumps have the same flow rate?
4/ Wouldn't a rear or full length pan be better? Who makes one other than Ford for their Vans?(must require a hell of a long pick-up tube!)
5/ My FPP rocker Stands do not allow the use of the sheet metal baffles originally installed to aid oil drainback and keep the valve guides from flooding. Do I really need the baffles? (obviously FPP doesn't use them for their own vehicles)
6/ I plan on using 20W50 with bearing clearances around 0.0025". Won't this oil, when cold, prove so thick, that drainback could be compromised to the point where the pan is sucked dry by the pump? (probably not a problem in sunny California, but it may be up here in Canada)
Thank-you for your inputs. |
