How do you know if your valve timing is off?
What are the symptoms of a bad timing?
- Engine Has A Ticking Noise: A series of pulleys attach the engine timing belt the engine’s camshaft and crank, allowing the crankshaft to power the connecting rods that are attached to pistons.
- Engine Won’t Start: If the engine timing belt has broken, it won’t be able to start.
What happens if timing is too far advanced?
If ignition timing is too far advanced, it will cause the fuel-and-air mixture to ignite too early in the combustion cycle. This can cause the amount of heat generated by the combustion process to increase and lead to overheating of the engine.
How often do you change the valve on a Toyota 3s?
As there are no hydraulic lifters on the 3S engine, you need to adjust the valves every 20,000 miles (30,000 km) of mileage. Valve clearances for a cold engine are as follows: inlet 0.19 – 0.29 mm, exhaust 0.28 – 0.38 mm. 3S GTE/GE firing order – 1-3-4-2. The timing gear uses a belt requiring replacement every 60,000 miles (100,000 km) of mileage.
When was the Toyota 3s FE engine made?
This engine was manufactured by Toyota Motor Company from 1986 to 2003. The Toyota 3S-FE features a cast-iron cylinder block and aluminum head with two camshafts (DOHC) and four valves per cylinder (two intakes and two exhaust).
What’s the difference between Toyota 3SGTE and 3sfe?

What’s the compression ratio on a Toyota 3s Fe?
The 3S-FE has a cast-iron block, forged steel crankshaft, and five main bearings. The cylinder bore is 86.0 mm (3.39 in) and the piston stroke is 86.0 mm (3.39 in). The compression ratio rating is 9.5:1.
