Where is the timing chain on a Saturn I4?
The 1991 to 1998 DOHC engine had an upper timing chain guide in between the camshaft sprockets. The timing chain was lubricated via cast-off from the top of the cylinder head and one ‘squirter’ on the oil pump housing. The SOHC and DOHC engines used different timing chain sets.
What kind of engine does a Saturn’s have?
The powerplant used in Saturn S-series automobiles was a straight-4 aluminum piston engine produced by Saturn, a subsidiary of General Motors. The engine was only used in the Saturn S-series line of vehicles (SL, SC, SW) from 1991 through 2002. It was available in chain-driven SOHC or DOHC variants. This was an…
Where is the camshaft located on a Saturn I4 engine?
The SOHC and DOHC engines used different timing chain sets. The SOHC (LK0/L24) cylinder head had 8 valves and was made of lost foam cast aluminum. The camshaft was located in the center of the cylinder head and driven by a chain off the front crankshaft sprocket.
How many valves are in a Saturn I4 engine?
The DOHC cylinder head had 16 valves and was made of lost foam cast aluminium. The camshafts were held in the cylinder head with bearing caps and driven by a chain off the front crankshaft sprocket. Motion from the camshafts was transmitted to the 16 valves by direct-acting hydraulic lifters.
What causes a timing chain to break on a Saturn?
The old style timing chains have an oiler nozzle that does not provide adequate oil flow under certain conditions, such as starting and low RPM idling, which can cause the timing chain to break and causing engine failure.
Are there any problems with the Saturn L series?
“The Saturn L-Series vehicles have been plagued by problems from the very beginning,” said NCCC Vice President Brian Reitter. “To this day, complaints about the L-Series have never subsided.” Reitter says that the most common complaint continues to be the defective timing chain.
Is it safe to buy Saturn L in NC?
The North Carolina Consumers Council (NCCC), a nonprofit consumer education and advocacy organization that has been representing the interests of North Carolina consumers since 1968, is advising consumers against purchasing any Saturn L-Series vehicles with 2.2L engines due to a significant risk of timing chain failure.
When did NCCC start investigating Saturn L series?
In 2003 NCCC petitioned the National Highway Traffic Safety Administration (NHTSA) to investigate repeat tail light and brake light failures in Saturn L-Series vehicles.
When did the Saturn I4 engine come out?
This engine was used from 1995 to 2002. The SOHC engine was available on the base model S-series vehicles (SC1, SL, SL1, SW, SW1) 1992 through 1998 L24 cylinder heads developed issues with cracks developing in the fifth camshaft journal, located closest to #4 cylinder.

When does a Saturn’s series engine fail?
The aftermarket replacements have a quality problem; best bet is to find a low mileage junkyard replacement or order the OE part (~$70). Not hugely common, but still a recurring failure. They usually fail when the engine is hot. You’ll be driving along, and suddenly the engine dies, and won’t restart until it cools.
