The Fiat 2.4 multiair engine is a hydraulically-actuated variable valve timing and variable valve lift engine technology. It is one of the best Fiat engines and Fiat Chrysler Automobiles introduced it in 2013. But like most engines, it also comes with several problems. So, what are Fiat 2.4 multiair engine issues?
Some of the common problems with the Fiat 2.4 multiair TigerShark engine are high oil usage and oil leaks. Despite recording several problems, this engine is very durable and efficient in performance. What’s more, these issues can be avoided with proper care and maintenance.
What are the common problems with Fiat 2.4 multiair engine?
High oil consumption
This is the major problem with Fiat 2.4 multiair Tigershark engine. Many users of this engine have complained about spending a lot of cash on oil. If you conduct a quick Google search of oil consumption problems on the 2.4-liter multiair engine, you will be bombarded with a lot of results. This just shows you how this engine consumes excessive oil.
What’s more, there is a class action lawsuit floating around concerning excess oil usage on the 2.4 multiair engine. Most people have repeatedly said that their engine uses over 1 quart of oil every 1000 miles. This is ridiculous as the recommended average should be 1 quart of oil or less every 1000 miles.
After a thorough review of the problem, most mechanics have stated that the excess use of oil is because of pistons or piston rings. It is said that too much oil passes through the rings, enters the combustion chamber, and is burned away. Even though using excess oil doesn’t hurt the durability or reliability of the engine, running too low can cause severe issues.
Some of the effects of low oil levels are knocking, grinding, and clunking sounds. Other effects include poor performance, engine overheating, burning oil smell, car stalling, and poor fuel economy. Note that the check engine light rarely comes on when the oil is low. So, you must check and ensure you’ve got the right oil level before it’s too late.
It is recommended to refill your oil every 1000 miles. This might be expensive but it’s better than spending a lot of money fixing or replacing some parts due to low oil levels. Furthermore, since the problem has to do with the pistons, using thicker oil is crucial as it helps to minimize oil usage due to the design flaw.
Oil leaks
Another problem that the Fiat 2.4-liter multiair Tigershark engine users have reported about is an oil leak. This problem is not only common in the Fiat 2.4 multiair engine, but all Fiat engines. It is usually experienced on older engines. Besides, there are several gaskets and other sections of the engine that become brittle with age, heat cycles, and mileage.
Some of the parts that become faulty and lead to oil leaks are oil pan gaskets, valve cover gaskets, and main seals. But in the Fiat 2.4 multiair Tigershark engine, failing valve cover gaskets are the main culprits. Note that the Valve cover gasket lies at the top of the engine and it takes a lot of abuse over the years.
However, the valve cover gasket, which is a rubber-like section is prone to degrading with age and mileage. Some of the signs of oil leaking are visible leaks, light smoke, burning oil smells, and low engine oil. Nonetheless, leaks start small as valve cover gaskets start to degrade ad start cracking.
To fix this problem, you will be required to repair or replace the damaged or faulty parts. Even though replacing the valve cover gasket is cheap, it can be time-consuming and the labor costs can be pretty high.
