Ford 460 engine questions/issues

[TheWanderer]

Hey everyone, new to the forums and new to RV ownership. (Owned about 2 months now).
Firstly, HI! nice to join a community of like minded travelers!

I own a 26 foot 1988 ford gulfstream rv.

Ok so I am doing a fairly major overhaul on the Ford E350 v8 460 block engine. It has had a handful of things replaced already (starter, map sensor, pcv valve and tubing, spark plugs, etc etc.) and now I am working on lifting the engine to access the oil pump and crankshaft bearings. I just had a couple things I have run into I am unsure on.
Firstly, does anyone who has done work on this engine have any further tips for oil pan removal?? I have never had to go through so much just to get the dang oil pan off on a vehicle! The frame is 1 inch below the 7 inch deep oil pan. So in order to get the pan off and around the oil pump and crank and such, I have to lift the motor at least 5-6 inches. That meant removing a LOT including the throttle body, which leads me to my second question.
I cannot seem for the life of me to find a matching replacement for my bottom gasket for the throttle body, where it mounts to the engine. I will try and link a photo of it to show what mine looks like, but i cannot seem to find a replacement anywhere! It flaked some upon removal of the throttle body.


Thanks in advance for any advice or help!! I am quickly learning a LOT about this engine and RV with all the work i am doing. (I was basically scammed in purchasing a used RV. Tip for others/the future, GET SOMEONE TO INSPECT IT FIRST!)

Hope y'all have a great day, happy trails!

From your description and the picture those are fuel vapor canisters. The are attached via the vent line to the fuel tank and the purge solenoid.

When the vehicle sits especially in the sun the fuel in the fuel tank heats and emits vapor. The excess pressure in the tank and the associated hydrocarbon (unburned fuel, a major ingredient in smog) vapor pass through the canister on the way to vent to the atmosphere. Inside the canister is an activated charcoal that absorbs the hydrocarbon out of the vapor so the hydrocarbons do not escape.

Now when you start the vehicle the purge valve opens for a set amount of time and pulls fresh air through the canister and into the engine. As the fresh air is traveling through the canister is strips the hydrocarbons out of the charcoal and into the engine to be burned.

Yeah if I can't get good enough access to get the oil pan off and do the work, I will definitely bite the bullet and pull the engine. I already have a stand and hoist rental lined up if need be.
I did have another question though I forgot to ask earlier. There is a ruber line I need to replace that runs from the purge valve solenoid in the PCV system down to these components that look almost like batteries?? (PCV runs to purge valve solonoid then splits to 2 lines, one runs to the intake I believe, one to these boxes through a hard line) Anyone happen to know what these components are for? Possibly part of the EGR system? I suppose I could dig through my electronic ford factory manuals and possibly find out, but if someone knows it would be much easier.
I am by no means an expert mechanic but I have a fair amount of knowledge and experience. Still learning. 🙂
Here is a photo of the boxes I refered to.


Thanks again everyone!! 😄

bite the bullet,, just pull the engine then you can do the hole thing,standing up. bench test ,then you,ll know its good.

One of the methods used to get the pan off of those rear sump fords is to drop the pan as far as possible and drop the oil pump. The tough part is removing the main bolt that holds the pick up tube.

Summit Racing has lots of 460 parts. That mill is used in racing.

I used copper exhaust gaskets from them.

I converted to studs.

Also, I reduced the photo size, hopefully that is small enough. 🙂
Much appreciated!

Looks great now. You’re welcome and good luck with the rest.

If you don’t already use them, RockAuto is a fantastic place to buy parts.

Agreed! I get virtually everything from either RockAuto, or Advanced Auto Parts with a 25% off online order coupon.

Welcome to the forum. Please reduce the size of your picture so people can read your text and the replies. Edit: I see you reduced it some. A little more please. 😉

Here is the gasket you’re looking for. It’s called an intake plenum gasket.
