Honda CR-X Si
Honda Motor Co. (Ltd.) produced a high performance automobile with fresh light weight unique styling. Producing these automobiles, such as the suspension mechanism small part with a design toward high-performance and high density engines", the thought of Man-Mecha (Man (Man maximum), mecha (Mechanical minimum)) grounded the developmental process. The front suspension and maneuverability, with the torsion bar suspension strut with superior turning round, uses a trailing-link beam suspension with excellent high speed stability. In addition, a unique and fresh styling and excellent aerodynamics, new lightweight material used, highly rigid monocoque body, Honda's unique mechanism, the Autasuraidosanrufu, provides equipment to enable high-precision construction with the panel on the roof panel that slides. It is the world's first mass-produced roof ventilation.

Valve Guides
Valve Springs and Valves
If experiencing rough acceleration and loss of power (bogging down and backfiring) between 500 to 2800 rpm and find oil in the spark plugs well and wires, the spark-plug tube seals are leaking. They are part of the valve cover gaskets; the oil is getting in there and causing a misfire. Replace the valve cover gasket, tube seals, plugs and wires.
Valves, Springs and Seals Installation
- Coat valve stems with engine oil
- Install the valves in the valve guides
- Check that the valves [move up and down smoothly]
- Install the spring seats on the cylinder head
- Install the new valve seals
- Use valve guide seal installer [Stem seal driver]
Timing Belt
Timing Belt : Honda Part Number, 14400-PK2-004 (88 Prelude 2.0 Si)
Ignition Timing : 16 degrees + or - 2 degrees at idle speed is the stock setting. (Red Mark on Crank Pulley, it also has a mark either side of it. The other mark off the left is the top dead center mark). Turning the distributor clockwise retards the ignition, and turning it anti-clockwise advances the ignition.

"Open loop" operation9
Unplug all the sensors, and start and run while not responding to "stimuli" from sensors. When do so, ECU will revert to a basic set of maps (original environment model). If it still performs poorly or nothing much has changed, it's nothing to do with the sensors, and has everything to do with the engine itself.
Petrol Gas Filters : Change every 50,000 miles (Honda recommendation)
Gas Filter : WIX Part Number, WF8073 (Under Hood Bonnet) | Honda Part Number, 16010-SH3-505

ECU Code: PM6
Resetting the ECU : Fully warm up engine, Locate the fuse box under the bonnet, (Above passenger side wheel arch) and remove the fuses for the ECU and Hazard Warning for 2 Minutes. Refit fuses and start the engine, leave it at idle speed for 5 minutes. (Do not go near the throttle) The reason for leaving it at idle speed is to let the ECU calibrate itself to the sensor readings and program a default value for itself.
