What are common problems with the 7.3L Godzilla?
Again, it’s too soon to talk about problems with this engine because cars with it haven’t driven a lot of miles yet. But there are some things we know for sure and will tell you about below.
Some Ford owners write reviews in which they criticize the company for some small mistakes in the engineering of this engine.
But if you read reviews of other engines made by Chevy, Chrysler, or Toyota, you’ll find even more criticism, so it’s fine. But let’s look for real problems with the 7.3L Godzilla engine.
Gas mileage
In a truck or van with this engine, you shouldn’t go more than 12 miles per gallon of gas. Yes, the Godzilla will use a lot of fuel, so it’s hard to say that it’s a cheap engine.
But if it wasn’t Godzilla, who would call it that? Ford gives us hints that this beast will quickly use up all the gas in the tank.
Oil consumption issues
We’ve heard of cases where this engine starts burning oil after 10,000 miles, which is crazy. It’s not a big problem, just a single one, but this kind of engine shouldn’t give its owner any trouble like this at all.
Spark plug wiring problems
Even in cars with few miles on them, the coils and wiring can cause problems. We can see that this problem is present in all of Ford’s big engines.
It’s important to know this because ignition coils aren’t cheap at all.
Timing system issues
You will have to keep an eye on the timing system because it’s not that easy. It has variable valve timing, which is supposed to save gas (really? ), but it’s not that reliable.
When something goes wrong with the timing system, the valves can get broken, and your car will need to be fixed.

Ford 7.3L Gas Godzilla Reliability
The Godzilla is still in its first year of production, which means that problems will come up.
Since these engines are still under warranty, most of these problems will be fixed for free and used to make the engine better in the long run.
There have been a few cases where the engine stopped working completely, but we think these are rare.
We think the 7.3 Godzilla will be a strong engine that can go over 300,000 miles and still be reliable even when pulling a lot.
Given how strong these parts are and how much power we’ve seen them make, we don’t think there will be any big problems with the block or the internals.
Even though we don’t know how reliable these engines are with major changes, we’re sure that they can produce some serious numbers based on the testing we’ve done so far.
What kinds of problems have you had with the 7.3 Godzilla so far?
Horsepower
Ford’s 7.3-liter “Godzilla” pushrod truck engine makes 430 horsepower and could make much more.
Weight

Final Words
We know for sure that the Ford Godzilla engine is one of the best extra-high displacement V8 engines in the world right now.
It’s better than some of its competitors, and it’s one of the most traditional engines in trucks and vans made today.
You don’t have to spend a lot of money to fix or maintain it. Yes, it will use a lot of gas, but the engine won’t give you any major trouble for a long time.
