Yes, you will need an oil injection block off kit to run a premix in a 2002 Blaster. The oil injection system is designed to automatically mix oil with the fuel, so if you are running a premix, you will need to prevent the oil injection system from injecting oil into the engine.
How many oil injection failures occur?
Oil injection failures are relatively rare, but they can occur due to various reasons such as:
* Clogged oil filter: A clogged oil filter can restrict the flow of oil to the injection pump, which can cause the pump to fail.
* Defective oil pump: A defective oil pump may not be able to generate enough pressure to inject oil into the engine.
* Damaged oil lines: Damaged oil lines can leak oil, which can lead to a loss of oil pressure and cause the pump to fail.
* Loose or missing injector bolts: Loose or missing injector bolts can allow air to enter the oil injection system, which can cause the pump to fail.
If you suspect that your oil injection system has failed, it is important to have it diagnosed and repaired by a qualified mechanic.
