Any Ford RV/ Motorhome experts on here?

Scotty is quite helpful.  I've been very pleased with his help.

Banks makes a lot of money selling headers and exhaust kits for RV's.... for a reason.

CI manifolds hold a lot of heat and restrict flow keeping heat from going on its merry way.

Especially with your foot to the floor for hours and hours.

While it may not be in your future, Scott is right on track with his advice. 👍

Speaking of Banks, what exactly does this kit below do anyway?

Um, conveniently oils your intake charge temp sensor?  
Notice it's SO good at that, that it can't be used ahead of a MAF.

K&N's do flow, but they need to get really dirty before they filter as well as a paper element.

Haha, well I know what the filter does...

What is the airbox cover for? Just a visual thing?

Why would one buy this kit over just a filter? Is Banks making their own filters?

I think it's oversized to hold the element (that likely has another application)

It's also good advertising to have their name in bold letters front and center on your engine.

As I mentioned above, Scott suggested a less restrictive air filter.

Are there options other than K&N or a K&N style filter for this?>..

A paper element filter is a paper element filter...don't they all flow about the same?

Before you use a K&N filter check this out and then make your decision: https://www.youtube.com/watch?v=sJ3L-E-ufYo

That was quite a good video I must say. Thanks for sharing. I'm not real keen on K&N filters anyway, so I'd not likely ever install one. I can see their benefit on race engines that are getting torn down all the time anyway, but on a low revving street machine, there's not much sense really.

Found this decal in one of the manuals last night. Kind of odd. Don't know where it was supposed to be. I guess to indicate that it was set up as an RV chassis and not something else....but at 31ft, it's not like it would end up being anything else either...

I finally got around to pulling the engine cover off this E350/460 tonight to have a look around, and I guess I have a minor case of the previous owner blues...lol, and man, getting that doghouse in and out of there around the big captains chairs is no joke.

Anyway...first up was the PCV valve that had obviously been out of place for some time.



Also noticeable in that picture is that the last exhaust manifold bolt is missing. Looking in the mirror below you can see it is broken off about an 1/8" inside the head.



I'm not too concerned about that broken bolt at the moment. The exhaust is currently not leaking...or least it isn't making that ticking sound that leaky exhaust manifolds/gaskets usually make. The engine was sounding pretty good actually, what little bit I have heard of it.

Question for you 460 experts though...what is this sensor in the very back of the block, just in front of the trans bellhousing?



I went looking for the coolant sensor for the gauge in the dash, and it appears to be a typical 1-wire sensor right behind the thermostat, next to the distributor, so I'm going to test that this weekend. The gauge works, but barely. I am assuming bad sensor, but I'll short it to ground, and also check actual temp of the coolant with an IR gun.

Found this bracket loose on the driver's side. It is supposed to be mounted on a manifold stud (I assume). It is the mounting bracket for the EGR solenoid valve, and others. I am assuming that the exhaust manifolds have been changed...they are really way too clean to be 27 years old, and I've found some missing nuts, etc, like somebody has been in there.



I also found a loose open ended vacuum hose, so there was a good 3/16" vacuum leak...not sure how much difference it would make, because like I said the thing seemed to be running OK.

I also found that there is a hose/connected to the oil filler pipe, and I don't know where it is supposed to go when everything is connected as it was at the factory.

Cory - I think that is the oil pressure sender.  That's exactly where my tee with the sender and switch go.

By the way, what are you missing now?  I may have found a source.

As for the bracket, I should have a pic that shows where Huck's bracket was.  I'll go look.....

Gary, I bought most of the air cleaner/intake assembly in two sections. One half coming from Texas, and the other half Connecticut. I'm pretty sure everything is there, but the one piece I am still for sure missing is the elbow in the picture below as well as whatever type of clip or grommet holds it in place. It does not appear to be a separate part from Ford, it is part of that intake duct piece. If I can't find it or another duct, I'll just make something out of a PVC elbow or something.

Definitely the oil sender, not sensor...
Later 460's have a mod to make the gauge more linear, rather than (basically) an idiot light.

The rearmost exhaust bolt is why I said to slot the front and back ears of the manifold.
So shear stress doesn't break the bolt or crack the manifold.

Man, at least you have access, with the doghouse removed.
It's a nightmare to repair when it's up against the firewall.

Cory - I had a gentleman in my shop today that has a '91, I believe, motor home with a 460 in it.  Last I knew it wasn't running.  Although I don't know what he plans to do with it I can contact him to see if it has that piece if you'd like.

Gary,
Don't worry about it for now. I'll wait until I get everything assembled and installed and see how it goes.

Cory, I'm willing to bet you could find an elbow like that, that fits both the hose and the grommet, in Dormans HELP! line.

It's pretty amazing how comprehensive it is, even though you only see the popular pieces on the shelf.

Ya I'm not too worried about replacing it, either with something like a Dorman part or something from one of the industrial shops. There's a shop a few hundred feet from my work that specializes in all of that plastic tubing and hose, etc.

I got a bunch of the parts I needed Jim from your great state of CT! I trolled the damn internet for days and days trying to find this stuff, and as it turned out, the parts, as obscure as they are (1992-1996 E350 specific) were not that hard to find. Problem was getting people to ship them, even within the US. I found the identical RV, same year and everything, being parted out in Oregon and the guy said I could have all of the parts for $40 bucks...lol, but he wouldn't ship them to Maine. I came across and ad in Hartford for a guy selling a hood off a 1993 E350 cube van, so I asked if he had any other parts...which was a bit of a long shot as many of them were diesels, but sure enough he did have a bunch of the parts I needed, and he did ship them for me. Anyway...I chalk it up as a bit of OCD...lol, but I wanted the factory intake system replaced on this thing, even if it does absolutely nothing other than lighten my wallet. I live with it.

It does much more than that.
It gives you a concrete baseline, and the availability of parts and service, as you move away from propane.

Now, with that big tank you can have ice cold A/C in this beast all summer long!

Well, I like having everything connected properly and not have loose hoses hanging everywhere. I am in no way going to hotrod this thing, but I do want it to work it's very best, and when 7.5 mpg is the norm, every little bit counts...lol. My goal is to get it back to a stock baseline mechanically, and remove any and all error codes from memory, and have the thing to it's KOER tests without issue.

After that, swaybar bushings, steering stabilizer, and shocks and alignment, and that will be it.

I appreciate all the help guys. Thanks.
