Re: 'Summit' style mock up block?
The concentric pump would have the pickup attach to the timing cover I think. So the pan would be just a little deeper in the front.
With the pickup midway the Buick V6 pickup (5/8") is the one to use. Jim |

Re: 'Summit' style mock up block?
Here’s the 4.0 front cover with crank oil pump, and the port (circled) that is fed from the mid-block pickup.
And here’s the oil path from pickup port to crank pump… I thought the oiling diagram from the 4.0 and 4.6 overhaul manual might add clarity, but its flow paths on the diagram are just generic "tubes", and not actual parts. Then I saw this a few pages later, showing the sump with a note that its an early engine version. Maybe that's the point of confusion, that there are two flavors of sump styles for the 4.0 and 4.6?: Edited 1 time(s). Last edit at 05/25/2023 08:34PM by Roverbeam. |

Re: 'Summit' style mock up block?
So what is that port for with the red o-ring in it? Looks like it is for pressurized oil so, gage sender maybe?
Also I don't see why an old style pan would not work there. Jim |

Re: 'Summit' style mock up block?
Okay, here's the skinny on the two Rover pans for the 4.0/4.6 V8. It's GEMS vs Bosch.
"On a GEMS setup that is where the oil pickup tube would mount if I'm not mistaken. Bosch engines = pickup tube runs to the front cover." [landroverforums.com] How to tell a GEMS from a Bosch. [www.roverparts.com] |

Re: 'Summit' style mock up block?
Thanks for digging that out. I’ll put a note back on my post with template downloads to that effect, for the next person that reads this thread but doesn’t follow it to the end…

Re: 'Summit' style mock up block?
Went away for a while, and this was waiting for me when I got back.
The only gotchas in assembling this is to be sure to do the oil pan panel last, and to carefully note the left and right intake/exhaust pieces - they're different to mimic the offset head locations. I could probably cleverly add little L & R symbols to be water jetted into the parts, but I thought that would just drive up cost. I assembled mine just looking at the 3D pic on the 1st page of this thread, and it was easy enough. I'm going to modify the files to include a 1/2" brake bend in the panels for the intake and exhaust - they're a bit flimsy as flat, pierced sheet metal. I did this for the motor mount panel's top edge, and it helped a bunch. So the updated files will look like this: The waterjet company I used will do simple bends like these, or if you have the means to put a 90˚ bend in .030 steel it's easy enough to do.
