There is a romantic version of the barn find. We’ve all dreamt it. You pry open a forgotten garage, wipe dust off the fender, crack the hood open, splash gas down the carburetor, and suddenly an engine that hasn't run since the Nixon administration fights its way back to life in a convulsing, smokey, celebration. Then it’s simply a matter of throwing on some fresh rubber and hitting the road. But this isn’t a YouTube show; it’s not as simple as it appears.

Crashing back to reality, many of these finds come with a significant amount of the floorboards missing, rusted-shut brakes, and an engine so seized it may have just fused into one solid piece of iron.

My 1963 Rambler Classic 660 wagon falls closer to the latter.

I've always been attracted to AMCs, and years ago I traded a G-Body wagon parts car for this abandoned Rambler. Then, in true project-car fashion, I promptly created my own Barn Find by letting it sit in my shed for another four years. I know it has been dormant for at least a decade, but after looking closer at what is—and isn't—still intact, I suspect the real number may be closer to 40.

The Rambler is rough. The front floors have largely returned to the earth. Rust has consumed areas above the taillights, lower fenders, and portions of the cowl. At the same time, it is surprisingly complete, still carrying details like the original-style air cleaner, washer bag, and trim. Granted the 198-horse, 287 cubic-inch looks beyond hope… it’s worse off than the rest of the wagon.

That made it a good guinea pig for a question almost every old-car person eventually faces: When you find a long-dead car, where do you start?

For answers, I went to people who do this regularly.

Dustin Hallinan and John Brito of Driveway Finds have built an audience around rescuing dormant cars and the occasionally ridiculous problems that come with them. Joshua Troy Dillon, better known as SleeperDude, has made a similar habit of reviving vehicles most people would walk past.

Both parties talked a lot about rebuilding engines and machine work, so I also called a friend, Dennis Borem, owner of Pro Motor Engines, for the perspective of the guy who has to deal with what happens when enthusiasm and a breaker bar go too far.

First, Figure Out What You're Looking At

Before buying parts, take a minute and study the car.

Driveway Finds photographs cars before disturbing them. Part of that is obvious—they make videos—but Dustin said they would document the car even if the cameras weren't there.

“It’s good to document it because you could find a barn find that’s one of a kind or something that’s untouched for so long. This is a cool part that adds to your car’s story, and it’s the next chapter for the car,” said Dustin.

My first question is always, ‘Why was the car parked?’ Brito calls the process “part investigation,” and that may be the most useful way to approach it. Previous repairs, abandoned parts, and even trash can provide clues. They have found vehicles with piles of ATF bottles that suggested transmission problems, and cars with fresh ignition parts where somebody had obviously been chasing a no-start condition. SleeperDude Dillon does the same thing. He looks inside the cabin and trunk for evidence of what the last person was working on. In one Opel GT, wiring diagrams and abandoned electrical work eventually led him to a failed ignition switch.

The Rambler had clues of its own.

Inside were sandwich bags filled with removed trim and door hardware. Under the hood was a two-barrel Holley carburetor that appeared to have been adapted from another application. It wasn't properly secured, several connections were missing, and the throttle blades were badly rusted. The radiator was missing clamps, fan, and shroud, which means it was likely pulled and only partly reinstalled.

Someone had apparently started working on this engine before me, and whatever momentum they had ran out long ago. Those are bad signs for me, because if someone else started and then stopped, it’s possible something broken was too extensive or pricey to be worth fixing.

SleeperDude Dillon says completeness matters. If he finds an old car that's been sitting for years with the carburetor removed or spark plugs missing, his expectations immediately drop. An engine left open to moisture has had years to rust internally.

My spark plugs, surprisingly, looked decent. Unfortunately, the engine did not want to move.

Make Sure the Engine Is Actually Stuck

Before attacking the crankshaft, eliminate the easy stuff.

SleeperDude Dillon recommends removing the drive belts first. A seized water pump, generator, or other accessory can make it feel like the engine itself is locked. He learned that firsthand on one of his own revivals.

I didn't bother saving the Rambler's ancient belts. I cut them off and tried to spin the engine with a breaker bar and socket.

Nothing.

Next came a cheater-pipe extension. Still nothing.

At that point the old AMC mill had earned the technical diagnosis of stuck-stuck.

Pick Your Penetrant, Then Be Patient

Everyone has a favorite recipe for freeing a seized engine.

Driveway Finds likes a 50/50 mixture of the cheapest automatic transmission fluid available and acetone. Brito's reasoning is simple: the acetone helps the mixture creep into tight spaces while the ATF leaves lubrication behind. They've used the combination repeatedly on engines that had been dormant for decades.

SleeperDude Dillon tends to reach for Marvel Mystery Oil. He has also used PB Blaster and other penetrating fluids, but his most consistent recommendation was not necessarily the brand—it was time. Let it soak.

I’m a big fan of Marvel Mystery Oil as it was originally designed to clean and lubricate fuel systems. Both factors are important with a stuck engine.

But I started with the Driveway Finds mixture and initially poured it down the intake. Then I remembered the obvious problem: only the cylinders with open intake valves were guaranteed to see much of it.

So I removed the plugs and fed the ATF-and-acetone mixture directly into each cylinder.

Then I waited.

Two weeks later, I put the breaker bar back on it.

Nothing.

That's where the next question comes up and tends to make things more complicated.

How Hard Should You Pull?

SleeperDude Dillon's answer can become pretty aggressive.

He recently worked on an engine that had been dormant for 66 years. After soaking it and exhausting the normal methods, they welded a five-foot bar to the crank pulley and started pulling.

“Even though it had the plugs in it and the carb on it, it was just locked up solid. So, we ended up having to get a five-foot metal bar and weld it to the crank pulley before we finally got it to start moving and turning.”

He has bent pushrods freeing seized engines, pulled them back out, straightened them with a hammer and put them back into service. On one FE-powered wrecker, seized rocker arms and bent pushrods were part of the revival process, yet the truck eventually returned to work around his property.

His logic—and Driveway Finds largely shares it—is that once an ordinary engine is completely seized, the worst-case scenario may already be a rebuild. Freeing it can at least tell you what remains usable. Brito put it particularly well, “A seized engine is a dead engine. That's a body with no heartbeat. So, anything after that is a gift. People get all in their own head about, ‘Oh my gosh, I’m going to hurt something.’ What are you going to hurt? It’s all garbage unless you unseize it.”

There is, however, another side to that argument.

Engine builder Dennis Borem has seen what happens after the breaker bars get longer.

“It’s like when a guy breaks a bolt, and then he tries to drill it, and then he breaks the tap, and then he brings it to me and has me fix it,” he said. “You’d have been better off just not breaking the tap and bringing it to me in the first place, because we could’ve done this a lot easier.”

His point is simple… if the engine is already headed to a professional machine shop for a full rebuild, there’s value in leaving it intact. “If they’re taking it to somebody to rebuild their old classic engine, the shop’s going to want to have it together anyways.”

When I specifically asked about putting enormous force into a seized engine, he confirmed the concern. “You can break the rings,” he said. His rule of thumb was more conservative: if penetrating fluid and a reasonable amount of effort get the engine moving, you're probably okay. If it takes extreme force, you may be creating additional damage.

I’ve heard Dennis say this many times: “I’d rather have them bring the engine. It’s always harder when they bring engine pieces.”

Those aren't necessarily conflicting opinions. They establish a sliding scale.

A common engine you intend to tear apart yourself is one thing. A rare, valuable, or numbers-matching engine headed to a professional machine shop deserves considerably more restraint. Even Driveway Finds said they slow down when the engine itself is valuable.

If It Turns, Keep It Simple

Suppose the engine finally makes a full revolution. You're not done. You have simply earned the right to move on to the next problem.

SleeperDude Dillon reduces the next step to the fundamentals: compression, fuel, and spark.

After manually turning an engine through complete revolutions, he'll use the starter and check whether the cylinders are producing compression. From there, old points, carburetors and fuel pumps become the usual suspects.

Driveway Finds takes a similar approach and warns against buying a restoration's worth of parts before you know what you have. Don't order the radiator, hoses and everything else just to discover that the engine has no compression. Establish that it has a heartbeat first.

Fuel deserves special attention. Dillon normally bypasses the original tank during the first startup, as do most others, and runs the engine from a clean external fuel supply, often a boat tank. That removes one very large unknown from the equation. I use a lawn-mower gas tank mounted on a light-stand with a universal petcock.

Top-End Problems

Unseizing an engine is the biggest challenge to overcome, but not the only one. All experts mentioned issues with top-end, like stuck rocker arms, bent pushrods, or stuck valves.

Dennis recalled a 302 Ford that had been rebuilt after sitting for years. Although the owner added fresh gasoline, and a bottom-end rebuild, enough varnish remained to stick valves in their guides and hang valves in place. Another tip is to pull valve covers and check for gunk on the valves and around the guides. Dillon added, “Our wrecker we use on our property, we took the valve covers off and I don’t know why, but those FE Ford big blocks are really bad for the rockers to just seize up, rust up. So, none of the rocker arms would move.”

“So, I got all the push rods out, hammered them all back out straight. We left the rockers in ultrasonic overnight and the next day we put them in the vice with a big pair of channel locks and started turning rockers one at a time.”

Will the Rambler Keep on Ramblin’?

For now, my Rambler hasn't made it very far.

The cylinders have soaked. The accessories are disconnected. The oil has been checked. The plugs looked better than expected. I've leaned on a breaker bar and then made the breaker bar longer.

The engine hasn't moved.

If I can’t unstick it, it’s not worth my time to continue. My desire is to use it as an organ-donor for other projects, but I have too many projects, and several AMC fanatics have expressed the desire to take a crack at the car. I don’t think I’ll be able to do the Rambler justice. They want to restore it, or at least rescue it, I don’t.

Don't Restore It Before You Rescue It

This may be the most useful advice Driveway Finds offered.

Break the project into stages.

First, make it run. Then make it capable of moving around safely in a controlled environment. Then work toward becoming a dependable road car. Don't look at a Barn Find on the first afternoon and fill a shopping cart with thousands of dollars’ worth of parts, especially if those parts go beyond revival and address restoration.

There will be plenty left to address. Brake hydraulics, tires, transmission fluid, cooling system, wheel bearings, driveshafts, and everything made of rubber deserve scrutiny before a long-abandoned car is trusted on public roads.

“It should just be running. Second stage is like, okay, maybe I can drive it down the road. Third stage is, okay, it’s good to go to my cars and coffee,” said John. “People often say, ‘Wow, this thing needs $9,000 worth of parts.’ It’s like, no, it doesn’t. Just get the project started today and the car will tell you what it needs.”
