I wanted to give you fellows an update on what's happening with the Milodon pan and Summit Racing.

Summit's tech guy said   "put on the stock oil pump".

Milodon said    "take two quarts of oil out"   it's probably the oil pump bypass.   Now, what the hell does taking two quarts of oil out have to do with the oil pump bypass

Jerks!

They say the oil is foaming and it's the motor's fault.  I said there is NO sign of foaming just loss of pressure.
I told them I ordered another pan to end the debate. 
I asked them if they would take it back if the pressure doesn't drop when I install the Armondo's pan.
We'll see what response that brings.

Seems they only want your money, they don't care if the parts actually perform as advertised.

When I put in the 460 I added an MSD 6AL box.   I had no spark at start up so I just bypassed it and went back to the standard wiring.  I used the white wire for the points trigger.

I haven't had time to check it out but have read that the MSD won't work with a mallory dual point distributor.  It's a new tach drive distributor.

Have you heard this rumor?  Does anyone have this setup running?

Are the armondo's only sold by them or are they sold by retailers?
I found his website and they are $399.   I don't know if that includes the pick up or not.
The website isn't very informative.

I guess I should ask if anyone has one of these pans for sale and how much.....

I could just dump mine.   It looks like a complete rebuild to fix mine!

I better not have a problem with a front sump pan... I can't use a rear sump.  I wish I could but the jet intake angle prevents that.

Does anyone have any pictures of the inside of any other marine brand oil pans??  That would give me an idea of what to look for.

This thing has a windage tray in it.  Do you think I need to make that wider?  Longer?  Angle the sides of the windage tray downward?  That's where the pictures would be a big help.

I can do just about anything to the pan.  We have quite a machine & metal shop here at the plant.

The pressure is being taken off the rear of the motor.  The oil filter is a half size K&N filter.  The long filters hit the frame rail.  These filters have caused no issue since I bought the boat in 1978.

I did change the filter, pulled the engine and verified the pick up gap which I thought was the issue.  It was short.

I called Milodon and They said to take two quarts out.  That will verify pump or windage.  He's guessing pump, wonder why..... 

We'll see what happens next weekend with the new gauge and two quarts out.

On the oil pressure down due to the pressure relief not opening.
That came from an engineer who said the pressure build up causing the cavitation would kill the pressure.  Back off the pressure end the cavitation and the pressure returns.  I didn't come up with that.  He's a college boy engineer here at work,  they're allways right 

If it still drops with the two quarts out I plan on changing the pump Saturday night and going back out Sunday afternoon.  I'll take pictures of the baffeling and check the pickup tube, gaskets etc for signs of leakage. 

 If it drops again I'm calling milodon back.

It's a good thing these engines are easy to pull!

PS, I'm not worried about hurting the engine,  It doesn't go under 20psi and I don't keep the rpms where the oil pressure drops.   I'm just breaking in the engine slower which is better anyway.

I enjoy working on the boat so this isn't a big headache, it's a hobby.   I just want it right.

Could you tell me where the issue is with this pan?  I could modify it if need be.   I just need to know what part needs fixed.

That's an interesting theory but the dip stick marks the safe oil level below the crank reguardless of oil pan.  It is watching the clearance between oil and crank.

However I have learned a long time ago that nothing is impossible.  If the oil IS above the windage tray there is no sense having it as the crank would be in it.

 I'll drop the level to the lower limit.   With the extra capacity it should still have more oil than stock by a long shot.

I have close 400 bucks in this setup with pump, pickup etc.  I would rather fix this pan if possible.

 Does anyone know what the problem is with these pans if any?  It's hard to imagine that they are mass producing a faulty product.   Is there just a component in some of them that could be corrected?

My wife is understanding but not to the tune of throwing away 400 bucks just to buy another brand.... if you know what I mean 

Is the problem in the trap door area or what?   

I just finished a build of a 460, all new bearings, melling HV oil pump, 10 quart Milodon marine oil pan and pickup K&N oil filter.  Everything is new in this motor but the crank.  All clearances were checked and fine.

The issue is the motor holds 75 PSI of oil pressure till it gets to about 4500 RPM's.  That is where the problem comes in, it then drops to 20 PSI??

I know you guys have experiance with the oil pan so I'm posting this here.   I have a guy telling me the Milodon oil pan is the problem.  He thinks the oil is being sucked up by windage from the crank thus draining the pan? 

I'm thinking the oil pump may be defective, or an air leak in the pick up.  I'll be checking both when I pull the engine.

This thing runs great and sounds great.  I have not run it above the point where the oil pressure starts to falter.  This is all happening IN the water.   The pressure drops comming out of the hole and when sneaking up on 4600 on a glass smooth lake.

I can't see sloshing being an issue except when pulling up on plane.

 what do you guys think?   I ordered a new pump.

What do you guys think?  Have you ever heard of this before?
