7.3 Diagnose bad injector cup

If you have diesel in your coolant, lots of smoke at high rpms, and startups that involve a lot of choking and croaking, you might have a bad injector cup. To be sure of this, you will need to remove the injectors and pressurize the cooling system. At that point you can see the coolant squirting out of the bad injector cup.
Do not pressurize the cooling system above 16psi!
