Ford E-150 Econoline 1975-1979: Choosing Your Engine Timing Cover Gasket Set
Leaking oil or coolant from the front of your engine? It might be time for a new timing cover gasket.
- The primary symptoms of failure are external oil and/or coolant leaks from the front of the engine.
- This is a labor-intensive job due to the need to remove the harmonic balancer, water pump, and other accessories.
- Always replace the front crankshaft seal when replacing the timing cover gasket.
- Choose a quality aftermarket brand like Cometic, Edelbrock, or Victor Reinz for a reliable, long-lasting seal.
Is Your E-150's Timing Cover Gasket Failing?
On a classic Ford van like the 1975-1979 E-150 Econoline, gaskets get old, dry, and brittle. Heat and time are their biggest enemies. When the timing cover gasket fails, it can cause oil and coolant leaks that can lead to bigger problems if ignored.
Common Symptoms of a Bad Gasket:
- Oil Leaks: The most common sign is engine oil dripping from the front of the engine, behind the main crankshaft pulley. You might see drips on the ground or a coating of oily grime on the front of the engine and oil pan.
- Coolant Leaks: For V8 engines, coolant can leak from the timing cover area. This is because the water pump bolts through the timing cover into the engine block, and the gasket seals these coolant passages. A leak might look like a drip or leave behind crusty, colored deposits (usually green or orange).
- Engine Overheating: A significant coolant leak can lead to low coolant levels and cause your engine to overheat.
- Milky Engine Oil: In a worst-case scenario, a severe gasket failure between an oil passage and a coolant passage can allow coolant and oil to mix. This creates a milky, sludge-like substance you might see on your oil dipstick or under the oil cap.
Check for Leaks Carefully
Oil and coolant can leak from many places. Clean the front of your engine with a degreaser and then run it for a short time to pinpoint the exact source of the leak before starting any repairs. A leak from the water pump's 'weep hole' is a sign of a bad water pump, not necessarily the timing cover gasket.
Choosing the Right Aftermarket Gasket Set
For a vehicle from this era, OEM (Original Equipment Manufacturer) parts are generally not available. Aftermarket brands are your only realistic option, and many offer excellent quality. Gasket sets often include more than just the main gasket; they may come with a new front crankshaft seal, water pump gaskets, and sections for the oil pan.
Aftermarket Brand Tiers
When shopping for a gasket set, you'll find several brands. Here’s a general breakdown of what to expect:
- Premium Brands (Cometic Gasket, SCE Gaskets): These brands are often favored in performance and racing circles. They specialize in high-quality materials like multi-layer steel (MLS) and advanced composites that offer superior sealing and durability. For an engine that you are rebuilding or want the best possible seal on, these are a top choice, though they come at a higher price.
- Quality OE-Equivalent Brands (Edelbrock, Victor Reinz): These brands are well-respected and often supply parts to vehicle manufacturers. Victor Reinz is known for being an OEM supplier for many European cars and is regarded for its quality. Edelbrock is a major name in the performance aftermarket and their gaskets are designed to work well with their other engine components. These brands offer a great balance of quality and price for a daily driver or standard repair.
- Standard Aftermarket Brands: Many other brands provide reliable gaskets that meet or exceed original specifications. Brands like Fel-Pro (not on the provided list, but very common) are a staple for mechanics and are known for reliable, affordable gasket sets.
Pro Tip: Get a Complete Kit
Look for a kit that includes the timing cover gasket, a new front crankshaft seal (also called a timing cover seal), and any necessary water pump gaskets. Since you have to remove the crankshaft pulley (harmonic balancer) for this job, replacing the seal at the same time is a must. Some kits even include a repair sleeve for the balancer if it has a groove worn into it.
Typical Costs for Replacement
The cost can vary based on your location and whether you do the work yourself. The job requires draining the coolant, removing the fan, belts, pulleys, water pump, and harmonic balancer, which can be labor-intensive, especially in a van where engine access is tight.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Gasket Set | $30 - $48 |
| Shop Labor | $400 - $700 |
| Total Professional Installation | $430 - $748 |
Frequently Asked Questions (FAQ)
Do I need to replace my timing chain while I'm in there?
Since the timing cover will be off, it's the perfect time to inspect the timing chain and gears for slack or wear. On a high-mileage engine from this era, it's a wise and relatively inexpensive 'while you're in there' upgrade.
Do I need special tools?
Yes. You will need a harmonic balancer puller to remove the main crankshaft pulley. You may also need a special tool to install the new front seal without damaging it. These tools can often be rented from auto parts stores.
Do I have to remove the oil pan?
On many Ford V8s and inline-sixes, the timing cover seals against the front of the oil pan. To get a proper seal, you will need to at least remove the front few oil pan bolts to allow the pan to drop slightly. Some gasket kits come with replacement front oil pan seals for this reason.
Are there any recalls or TSBs for this issue?
No specific recalls or Technical Service Bulletins (TSBs) were found for timing cover gasket leaks on the 1975-1979 Ford E-150 Econoline. Any issues today are due to the age and wear of the original components.
Technical Specifications
Gasket set materials can include composite, fiber, paper, and rubber. Common engines for this vehicle include the 300ci (4.9L) Inline-6, 302ci (5.0L) V8, and 351ci (5.8L) Windsor V8. Ensure the gasket kit matches your specific engine.
