302/5.0 Expert needed...PLEASE Help??
There is a hole in the block, passenger side, that goes all the way inside...."NOT AN ACCESSORY HOLE"....I have stuck a 12" screwdriver all the way in....hole is threaded and is about 1/4" in diameter.......pictures attached....>WHAT is it FOR??????
********PLEASE************* |
Pictures, I hope
|
Can only get one per section....how do you guys get more??????
|
Hmmm....don't remember my 351 having a hole there.....
Is it an oil pressure port? Is there oil in the engine? |
Okay, sorry, I should have given more info.....I have located the oil pressure fitting hole, the water temp hole, and all other "known" holes. No oil in the engine yet as I am still building. I have been told, but with no assertiveness, that it is a clean out hole, it is and exhaust crossover hole, and lots of, hmmmm, I just don't know........................Please help?????
|
Does everyone else just have it plugged? If so, I'd just plug it and move on.
|
I've got an 87 302 HO in my factory five.I can't see in that area with the engine in the car,but it feels like just a plug.
|
I have a 84' 351 block. It has the same hole with 7\16"-14 bolt threads. It's only about 1" deep,. No plug, no worrys. My guess is it would be for an auto trans dipstick bracket.
|
I think it is where one of the two factory brackets attach that the engine is hung from while being installed at the factory. They are the first thing to get tossed when a block is stripped.

Okay, the dipstick and strap theroy sound good but why would it not stop at a certain depth?? This one goes into the inside of the block?? I'm going by the machine shop and boneyard later today to see if I can see another one.....any other expert opinions???

Here's a pic of the back of my block. You can see the hole you're talking about and what's behind it. Plug or not, it's your choice. It just goes into the flywheel/clutch area.
I don't know the original purpose - maybe some sort of sensor that picks up on the teeth of the flywheel? Or a manufacturing construction hole... Anyways, I think you can just leave it. I've run my engine without doing anything to the hole - no major oil spills or anything like that. Hope this helps. |
some of the fords used that hole for a knock snesor.while others drilled a tapped a hole on the pad behind the intake.Don't know what its original use was because I have seen them on blocks down in the late 70s too.Stan

Zipzip, I finally got to a shop and found a block on a stand and it is just as your picture. The hole goes into the clutch area behind the rear wall of the engine.....thanks for your picture.... I now know I can leave it alone.....thanks all, Earl

I also wondered and "worried " about that hole," holes in engines are bad". Don't know what it is/was for but it has never leaked, weeped or anything else. The local Ford shop mgr wasn't sure why it was there, nor did a couple of his older mechanics there is nothing in the shop manuals about it either, at least for the American versions of the 289-302. A Ford engineers"mystery" hole:LOL: |
Yep, a mystery it is.....I have sinced looked at a half doze or so blocks and some go all the way through and some are only about an inch deep???? Go figure..................
|
Earl, I use that hole to ground the block to the frame. I also think if you have a standard trans, the pivot ball goes in one of the holes in the block, maybe this one.

My '87 Mustang 5.0/T-5 has the same hole. Never was anything in it, 'cause I'm the original owner and I know nothing has been removed. I put a pipe plug it on my replacement crate engine. I didn't want anything getting into the clutch area. Doug |
Thanks Doug........
Oh, and by the way your second line in your signature section has also been stated as follows; "Opinions are like assholes, everyone has one, and most of them "Stink"." |
I have a 94 5.0 HO and it has a hole on the top and on the side.
Both, depending on application, were used for factory lifting devices is what I was told by a guy that used to work for Ford. Due to some clearance issue, they were removed after the motor was assembled.. Sound reasonable? |
