What to Look For When Buying a Jeep 360 Motor (Inspection Guide)

Acquiring a used engine, especially one decades old, requires careful consideration. Here’s a detailed inspection guide:

1. Source and Seller Reputation:

• Reputable Salvage Yards: Often pull engines, test them (if running), and may offer limited warranties.
• Specialized Jeep Parts Dealers: These often rebuild or test engines more thoroughly and understand the nuances of the AMC V8.
• Online Marketplaces (eBay, Facebook Marketplace, Craigslist): High risk, but potentially good deals. Verify seller reputation, ask for detailed photos/videos.
• Private Sellers: Ask for their reason for selling, vehicle history, and be wary of "too good to be true" prices.

2. Condition: Running vs. Core:

• Running Engine (Pulled from a running vehicle): Best-case scenario. Ask for a video of it running, check for smoke, strange noises, and oil pressure. A compression test is crucial.
• Core Engine (Non-running, for rebuild): Expect to completely tear it down and rebuild it. Price should reflect this. Focus on the integrity of the block and heads.

3. Visual Inspection (External):

• Cracks: Inspect the block and cylinder heads meticulously for any visible cracks, especially around freeze plugs, exhaust ports, and mounting points. Cracks are often deal-breakers.
• Rust: Surface rust on the exterior is common and usually not an issue. Excessive rust, especially around water jackets or oil passages, indicates neglect or prolonged outdoor storage.
• Oil Leaks: Look for excessive oil grime or drips around valve covers, oil pan, front/rear main seals, and intake manifold. While some leaks are normal for old engines, excessive leaks suggest worn seals or neglected maintenance.
• Signs of Overheating: Look for discolored paint on the block/heads (blueish tint), warped exhaust manifolds, or coolant residue. Overheating can warp heads or crack blocks.
• Mounting Points: Ensure all mounting points for accessories (alternator, power steering, AC compressor) and engine mounts are intact and not damaged.

4. Internal Inspection (if possible):

• Oil Pan: If the pan can be removed, check for excessive sludge, metal shavings, or coolant in the oil – all red flags.
• Spark Plugs: Pulling a few spark plugs can reveal cylinder health. Oily plugs suggest worn rings/valve guides; fouled plugs indicate fuel/ignition issues.
• Crankshaft/Connecting Rods: If the engine is disassembled, inspect bearing surfaces for scoring or discoloration.

5. Compression Test (for running engines):

• Crucial: A compression test indicates the health of the piston rings and valves. All cylinders should have consistent readings, ideally within 10-15% of each other. Low or widely varying compression indicates internal wear or damage.

6. Completeness and Accessories:

• Does the engine come with a carburetor (or fuel injection system), intake manifold, exhaust manifolds, distributor, alternator, power steering pump, and motor mounts? A complete running pull-out will cost more but save you time and money sourcing components.

7. Documentation and History:

• Ask for any available history, mileage (though often unreliable for old engines), and maintenance records. While rare, any documentation adds value.
