99 powerstroke bad injectors

Last week i had another injector go bad. #1 cylinder was almost full of fuel. Last year the same thing happened on the passenger side to #8 cylinder. im lucky nothing broke this time either when it hydrolocked. It is common for injectors to flood the cylinders when they go bad? I think this time i will replace all 8 with some 60 hp injectors.I have an early 99,with 114,000 miles, afe 2 , bully dog 6 pos , over boost aniliator, hx crossover.

Sounds, good, but I'm surprised you had 2 injectors go bad so close together. I understand they are almost 10 years old at this time, but they're very durable and usually last well beyond your 110k mark.

You'll love the increased HP, the cheaper then OEM replacements, but you might have something going on that is messing the injectors up! I hope not, but let us know what happens!

7.3 injectors

would fuel contamination make an injector flood the cylinder or more likely clog the nozzles???? The 60-80 horse injectors from scott@ mass diesel will be in this week. Got them for $1600 rebuilt.

injector issue

I see injector issues frequently,Have not seen one flood a cylinder yet.I assume you pulled the glow plug before you pulled the injector and cranked the engine over? then fuel shot out? When you remove the injector from the head and don't predrain the head the cylinder will fill with fuel and oil.As far as them failing so close together,it could be a fluke or you also could have a bunch of crap in your tank.Also make sure you stay ontop of fuel filter maintenance and you may want to check your fuel pressure.Low fuel pressure will kill injectors most definetly.If you have the dough replace them with the 60's but stock injectors usually last a while.

bad injector

Lawman...i knew it went bad because it was blowing white smoke running rough,motor was knocking. After i shut it off and went to restart the motor locked up and would'nt turn over. I had this happen last year on the passenger side of the motor.This time i guessed it was on the drivers side, took out all the injectors and turned the motor over by hand. lots of fuel came out of the second cylinder back.

injectors

Seattle...Ya i drained the oil via the 2 1/8 in allens and fuel via the rear of the head. i forget what number the cylinders are but last year third back on passenger side and this time second back on drivers side.
well yesterday i replaced them all with stage II from mass diesel. today had buddy hook up snap on to check hpop pressure and we got 480 psi @idle and 2200 an wot. Is this too low? For an Early 99. Have bully dog chip .
