Don't actually have an issue with injectors,,, yet,,, but I got to thinking about all the posts I've read with people and stuck inj. and losing a motor,, my question is

1/ are there really any symptoms that consistently point to a stuck inj?
2/ is the oil level the only way to pick up on a stuck inj.

I always like to be pro active rather than re active, my 07' 5.9 is doing fine buy I really don't care for the dip stick that comes with this motor,, I preferred the one I had on my 01', just doesn't seem to be user friendly. I always check my oil after the truck has set over night and I check the level every Saturday morning

any hints or experiences would be helpful,,

I run a Baldwin fuel filter in the stock filter housing and then a GDP with the
fleetguard fuel filter downstream of the stock one.

Thanks,,,
