I know that's what you're supposed to do..............but I've been lucky, I guess, and saved a few bucks over the years too!!!!!! Not trying to convert anyone, and I'm absolutely positive that changing your oil every 3,000 miles is a lot safer than waiting longer.

Oh, I almost forgot. What about gas? I was thinking that this was probably a lead fuel only kind of engine? Is 92 octane good enough just to run it for a few minutes every once in a while?

 

dont run premium, just normal is fine. for 20 bucks i think changing oil is a cheap preventive measure.

 

Yes, $20 is cheap, but after the last post, I did some math.

I figure I've put about 250,000 miles in since I've been driving, at least.
On my toyota 4cylinder almost half of that.

So. 250,000 miles divided by oil change every 3,000 miles = 83 oil changes
83 oil changes X $20 per change =$1,666.66 if I changed it every 3k.

250k divided by oil change every 12k miles = 21 oil changes = $417 I've actually spent.

So, I've saved about $1,200 in oil changes. Which is equal to about six of these crappy 1960's 289's. hahahahahhahahahahahahahahahaha

I'm going to say "CHANGE YOUR OIL EVERY 3,000 miles", but I"m not going to!!!!!!!!!! hahahahahhahahahahaha

You can laugh at me when you see me on the tow truck next week!!!!!

Sorry, I couldn't resist. Thanks for the tip on the gas. I thought it was hard on the valves to burn regular unleaded?

 

it is but premium isnt better and would make it "Ping" i believe, since its illegal to use lead additive most people that are building/rebuilding an engine replace the valves with hardened ones, although its not a "run 5k miles on unleaded then valves are ruined deal" they will still last quite a bit.

 

I would start with regular unleaded fuel. You could increase to a higher octane if you experience pinging (detonation). But, again, I'm going to guess that you don't have a high compression engine needing higher octane. If you are experiencing pinging you're probably looking at timing too far advanced.

Lastly, it is possible that there is enough lead deposits around the valves to prevent further damage. Like others have said, I'd probably just get it running and drive it till it dies.

Good luck.

 

do you have pictures of the whole car?

 

It's a jeep.

like a lamp.

 

the need for more octane will occur when the engine is under load. i can't imagine any condition that would add load to the engine when the car is sitting still.

 

Super long story........short version.
I walk my dogs every morning around the area I live. I saw two jeeps in a guys yard one day. One of them a cool flat fender cj3a. I tell the guy $500, and I'll take both of your hands. Three months later he calls and says, okay. He's even got the titles for that price. I had no interest in the green cj5 with the 289, but figured I try to sell it alone for $500 and thus get the orange flatty for FREE!!!!!!

Little did I know that this green 1956 CJ5 has two very rare FORD GPW Jeep axles on it. They're very rare, and stamped 7-28-1944. They may have been overseas in the WWII, and came back as surplus parts........and some how got under this CJ5. Not super valuable, but they are super collectible........I think that's why I got so excited about this 289. My neighbor was telling me it might be a gem in the rough......and so I came here.

Pictures. Okay. If I were a moderator here. I would permanently ban me for posting these!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!

I promise not to post here anymore.......well, unless someone asks for something like more pics.........

Thanks again, everybody.








Here is a picture of the bolts on the axles. Ford marked every bolt with a scripted "F" when they made Jeeps in the 40's. It's kind of cool.

 

An engine sitting that long should have the oil changed, then the distributor pulled, the oil system primed with a drill, the distributor re-installed, then started and run until fully warmed up, then the oil changed again. Do this, and you could begin driving it immediately.

That coil is a FoMoCo, not a Motorcraft. The FoMoCo, was replaced with the Autolite in 65, and when Ford sold Autolite in 72, they changed to Motorcraft. BTW, there's probably nothing wrong with your coil, and an original ink-stamped FoMoCo coil is a rare bird.
