The essential difference lies in the pressure experienced by the injectors, on a petrol engine it will vary between 3.5 bars for indirect injection and 120 bars for indirect injection.
Leaking injector on a petrol Toyota Iq: The different leaks
It should be noted that injector leaks on a Toyota Iq equipped with a petrol engine are rather infrequent. This is caused by the much lower pressure in the petrol intake systems. However, there are two types of leaks:
- Leakage from the top of the injector:
It is possible that you have a leak from the top of the injector, this is the portion that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:

Leaking injector on my diesel Toyota Iq
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion system generates very high pressure in the engine, as do the injectors. On these models, the pressure is more than 10 times higher than on the direct injection of car petrol engines, reaching 1800 to 2000 bars.
Leaking injector on diesel Toyota Iq: The different leaks
In the circumstance of leaking diesel injectors on your Toyota Iq, there are three several types of leaks:

- Lower the pressure before any work is done…
- Covering you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Regarding the repair part of your leak, it will frequently be restricted to swapping the seals that have failed:
- Identify the source of the leak
- Take apart the injector in question
- Replace the corresponding seal kit
- Reassemble the set up and tighten with a torque wrench in accordance with the manufacturer’s standards.
