Pull the pin from the hydraulic tensioner. Rotate the crankshaft manually by hand exactly two full revolutions clockwise to verify that all marks return perfectly to TDC. 5. Troubleshooting Common 1G-FE Issues
: Oxygen Sensor Circuit Malfunction (causes rich running conditions and poor fuel economy).
Because the 1G-FE was primarily sold in the Japanese Domestic Market (JDM), Europe, and Oceania, official English workshop manuals can sometimes be difficult to source. Look for the following official Toyota publication numbers for the most accurate data: Publication No. RM017E
When working on a 1G-FE, always refer to the appropriate service manual. Here's a summarized guide to some common procedures with critical torque data:

Since it lacks hydraulic lifters, periodic valve shim adjustments are necessary to prevent "ticking" and ensure optimal performance. Oil Quality:

Toyota 1G-FE Engine Manual: The Complete Guide to Specs and Maintenance
Before turning any wrenches, you must understand the foundational architecture of the engine. The 1G-FE features a cast-iron cylinder block for maximum durability combined with an aluminum alloy cylinder head to reduce weight. : Inline 6-Cylinder (I6) Displacement : Pull the pin from the hydraulic tensioner
: Lubricate the bolt threads and under-head seating surfaces with fresh engine oil. Step 2 : Tighten all 14 bolts in the sequence shown above to ) using a calibrated clicker torque wrench.

The 1G-FE utilizes a rubber timing belt to synchronize the crankshaft and camshafts.
Its construction features a robust cast-iron block combined with an aluminum cylinder head, making it durable yet relatively light for a straight-six configuration. 2. Technical Specifications (1G-FE) Troubleshooting Common 1G-FE Issues : Oxygen Sensor Circuit
Rotate the crankshaft pulley until the timing mark aligns with the "0" scale on the lower timing cover. Ensure the camshaft pulley marks match the alignment notches on the rear cylinder head plate.
0.25–0.35 mm (standard); some manuals specify 0.29–0.39 mm. Oil Capacity: 3.9L (refill without filter) / 4.1L (with filter). Pure FJ Cruiser Maintenance Intervals
