How many camshafts does an i4 DOHC engine have?
two camshafts
An i4 DOHC engine has two camshafts, while a V6 or V8 DOHC engine has four camshafts. Overhead-cam engines have three to five valves per cylinder, but usually two intake valves and two exhaust valves. Older engines and a few newer “pushrod” engines have a single camshaft in the cylinder block.
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.
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.
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…
What was the compression ratio of the Saturn I4?
The cylinder head was also redesigned to keep the compression ratio at 8.8:1 even with the flat top pistons and now featured provisions for an air injection reaction system. 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)

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.
