All 2 Known Issues
On the 1991-2002 Saturn SL, the 1.9L SOHC (SL/SC1) and DOHC (SL2/SC2) engines in 1991-2002 S-Series sedans (SL), coupes (SC), and wagons (SW) develop persistent oil leaks at the valve cover gasket and front crank seal by 80,000-120,000 miles. The DOHC valve cover gasket is a $20 part but the cover bolt holes strip easily. The front crank seal often leaks onto the timing chain area and drips onto the exhaust manifold causing smell.
Common Symptoms
- oil leak
- burning oil smell
- oil dripping from front of engine
- low oil between changes
How to Fix
Valve cover gasket replacement DIY (~$30 part); use a torque wrench to spec (89 in-lbs) to avoid stripping. Front crank seal requires harmonic balancer removal — $200-$400 at independent. Replace the cam seals at the same time on DOHC. If valve cover bolt holes are stripped, time-serts ($60-$100) save the head.
On the 1991-2002 Saturn SL 1.9L DOHC, the 1.9L DOHC engine in SL2 / SC2 / SW2 develops excessive oil consumption (often 1 qt per 1,000 miles or worse) by 80,000-150,000 miles. Root cause is coked oil-control rings — common to the engine's open-deck design and high tolerance for low-quality oil over its long life. Owners are sometimes startled to find the engine 2+ quarts low between changes.
Common Symptoms
- oil consumption
- blue smoke on startup
- low oil between changes
How to Fix
Ring-cleaning treatments (BG EPR, Sea Foam soak) cycled through oil changes can sometimes free coked rings. If consumption is >1 qt/1,000 miles, ring/piston replacement (~$1,500-$2,500) is the durable fix. Many owners simply top off and run the car until something else fails — these engines often pass 250,000 miles even with consumption.
