the 2nd tube goes in the 1st tube where the dipstick now sits. it has a bracket that bolts into the valve cover bolt. the 2nd tube ends above the fan. when you pull the dipstick out, it is about 5' long. 1st one I ever saw, I thought Wow, that would make checking the oil in my lifted 4x4 sweet. But alas, I never got around to it


look from 78- 96 vans

 

Okay, back to this.

Not sure what more to do on this.
I had the oil pan off this weekend to change the gasket and took a look at the dipstick while I had it apart. There was nothing blocking it and it looked completely stock. There were also tiny nicks in the oil pan where the dip stick had been bottoming out, so I know that it can't go in any further.

Still, though, I get no reading.

Here's how it is set up.

The top one is how my '81 is set up. The dip stick goes into the pan itself and takes a reading in the deep part of the pan. (Makes sense! Why change it?)

The bottom one is how my '84 is set up. The dip stick goes through the block and takes a reading in the shallow part of the pan.





However, it simply just doesn't touch oil. Thoughts?



Lol, that's just awesome.

 

My guess is the 84 (with the hole in the block towards the rear) is using a setup intended for a rear-sump pan.

My understanding is that rear-sump or front-sump was dependent on if a cross member was needing to be cleared or not, or maybe it was 4wd components in the way, don't remember.

 

My only thought on that is that the pan doesn't have a hole in it, so it's intended for an in-block dipstick.

Both my '81 and '84 are 4x4 Broncos with identical axles, cross-members, etc.

Looked up some pictures. Here's the two oil pans:

'81


'84


There's almost no noticeable difference between the two shape-wise that I can see.


Confused! And irritated...

I want to be able to check my oil level.

 

I have the same issue. I have an 86 F250 300 and put a 84 motor in it. Had to use the old oil pan because of the 4wd and clearance issue with the one that came on the 84. My dipstick is in the front and old one was in the back.....I don't know how to fix except to find another motor.

Hope that helps.

Of the above, what part numbers are you interested in?


EDIT: There are different part numbers for van dipsticks & tubes (not oil pans, though; for the pan, the numbers above are IT for 1980/89 4.9L engines so I'm apparently wrong in my premise about 2WD vs 4WD).

 

NumberDummy had posted the part numbers for the dipstick, but not the others. Thanks for posting those. I'll have to see if they're on the other parts. I'm wondering if at some point, the engine was replaced and they reused the '84 oil pan?

Even if so, the oil pan looks like it was used from 83 to 89, so that covers all the way up to when they went EFI, so it should be okay.

Maybe it's just the dip stick tube and dip stick that are incorrect.

 

I know this post is older than by a year, but I was helping someone else out with the same exact problem, and while I was searching for pictures, came across your problem.

The dipstick hole in the front of the engine block, between the distributor and fuel pump is for a front sump oil pan. You can't use that with a rear sump pan as it will bottom out and you won't get a reading.

There should be another hole in the back of the engine block, (depending on the year the block was cast) for the rear sump oil pan, between the oil filter and the oil pressure sender. as pictured here...

That is where your dipstick tube and dipstick needs to go instead of in the front location. 1983-1986...

If your block does not have the rear hole, you will have to use a 1980-1982 pan with dipstick provisions, and use the 1980-1982 dipstick parts.

Hopefully you got it figured out by now, but if not, hope this helped you out.

 

Thanks for the reply!
And no, I haven't been able to figure this out (and still am able to get no reading). I didn't know there were front sump setups. Does this mean it's not the original engine? I can't see a front sump being able to fit around the axle.

I'll look and see if there is a provision to screw the dip stick in in the rear. I hadn't thought of that before. If not, I have a spare oil pan that screws into the pan itself (not that I am really in the mood to swap them. ).

 

Yes these engines have either front or rear sump capabilities.

The 300 and it's sister engine the 240, have both been around since 1965 models.

The 240 shares it's engine block with the 300, and it was installed in the Econoline, and certain ford cars.

It could still be the original engine as most of the later 300 block castings that I've seen have both front and rear sump dipstick holes.

Now if it only has the front hole, then something is fishy with a swap.

 

Interesting. Went out and looked at it tonight and there was only an oil pan dipstick in the front of the block. No port on the rear of the engine and none on the oil pan. Wow, considering that the vehicle was bought locally, had only around 95k original miles when we got it, & only had one real owner before me, a non-original engine is a real mystery.

 

This is an easy mystery to solve. OK. Ford also made availble the 300 CID straight 6 for a variety of other applications including use as a power plant engine for compressors, irrigation pumps etc. The dip stick location on the block was for those specific applications necessarly drilled for a specific piece of machinery. Those engines were also deemed as industrial engines and not to be used in a vehicle, which makes it odd that your bronco has one in it, could be a service block installed at the dealership.

 

Not exactly.

As was explained earlier in this thread, the 1983 and newer used block type dipstick tubes and dipsticks.

If you look at this post here, it shows the E2TZ-6754-B tube bolted into the rear sump position in the block, with the E2TE-JA dipstick.

I just went out and checked my 1981 block, and I found provisions for both a front and rear sump block dipstick provisions, but neither one has been drilled. Both have what looks like a pilot hole however.





As you say, the 300 has been used for commercial applications. It also shares the engine block with the 240, which was used in some ford cars of the past.

What I find weird is that his engine in his 1984 does not have that dipstick provision at all, or maybe it's not been drilled like mine hasn't. If it was a original engine to the 1984, then it should be there. So that tells me that it isn't original.

If his engine does at least have a (what looks like to me is a) pilot hole like my block at least has, then could he drill it, or have it machined for it? hmmm...

Easier to swap to the 1980-1982 pan and dipstick...?

 

But, ya gotta first locate that stuff, no?

 

I just scrapped an 82. Sorry
