Drill or not to drill sump oil tray
Have found the bigend dipper trays in some engines drilled? why would this be done.
Thought the idea was to have a high level of oil in the dipper tray to lubricate the big end bearing and splash oil up into the piston to lubricate the little end bearing. |

Re: Drill or not to drill sump oil tray
You are correct! No holes needed. Needs to hold oil. Could be rust holes
oil floats on water, water causes rust holes. |

Re: Drill or not to drill sump oil tray
I don't think so!!!! Maybe if all bearings are pressurized? People come up with strange ideas.
I have four Caddilac threaded hubcaps that someone drilled,tapped, and installed grease fittings???? I guess they thought pumping the hubcap full of grease would somehow magically go into the wheel bearings. |

Re: Drill or not to drill sump oil tray
Do not drill holes if your engine is NOT pressurized to the rods. If you have holes in the dipper tray they will not hold oil after the engine is shut off. Every time you start the engine, the big ends of the rods will not get any oil until the oil pump re-fills the dipper troughs. The cam cylinder bores and pins will not receive any slash until the troughs are full.

I've also seen drilled dipper trays but chose not to use them .

they are above the trough so the big end still gets full amount of oil I have seen them drilled into earlier A Models Last edited by colin1928; 12-06-2014 at 12:45 AM. Reason: add |

Re: Drill or not to drill sump oil tray
I should add that most of the trays Have seen drilled match the punched trays perfectly as if their were done with a jig
Why would Ford retool to add this holes |

I think that he may be talking about dipper tray holes that look like these..... These are one of the 'mods', made to the pan/tray when full pressure system is used. BTW, there are other ways of doing things for full pressure system pans...this is just one. |

Re: Drill or not to drill sump oil tray
I thank Norway's wholes in the tray is for the over flow of oil to get back to the oil pan. I've heard of people making these larger.

Re: Drill or not to drill sump oil tray
The large holes alongside of the dipper wells were likely put there by Ford to increase the flow rate of oil to the bottom of the oil pan. I suspect that at high speeds, the oil level at the pump intake may get too low without the large oil return holes.
Under no circumstances would I drill holes in the dipper wells because splash lubrication is necessary for the cylinder walls, camshaft lobes and piston pins.

Follow this link to re-visit an older discussion on the same topic where James Rogers answers the question in his entry # 4, 6 and 11.

Re: Drill or not to drill sump oil tray
I have a B motor, fully pressurised but the guy who rebuilt it removed the scoops from the big ends and left the dipper tray out all together. It has done a few thousand miles with no problem but I don't like the way the oil pressure warning light comes on when I turn right. Maybe I should put a dipper tray from an A engine in for the baffles but put holes in the dipper troughs.
Any ideas/comments?

the baffles in std tray only work forward and back not side to side (right hand corners) normally you remove the tray and weld in baffles with swing gates in 3 directions all opening towards the pump |

Re: Drill or not to drill sump oil tray
That makes perfect sense, Colin. T/hanks. I'll knock up a couple of those, one for the B engine sitting unrestored in the shed that I might do one day, maybe not. My A engines are going soooo well.

Re: Drill or not to drill sump oil tray
I have a full pressure engine and am using a Stipe pump with a baffled sump. Check this post for more info
https://www.fordbarn.com/forum/posthistory.php?p=866884 Actually check the whole thread. I have rough drawings of the plates I made although they need some trimming to fit the pan correctly. Dick
