Hey guys i was curious to know is there a life expectancy on our injectors? They are stock and have 141k on them the truck isn't doing anything weird i figured I'd ask before its too late.

I forgot to add i don't have AE but i do have two full blown snap on scanners that i can rub some tests on.

 

I think that life expectancy and useful life are two different things... I got 215k out of the injectors in my truck, but they had had it and were done being useful. Still worked, but not well. It also depends on how well the truck has been taken care of since it was new. Ignoring the oil system and not keeping good, clean oil in it will destroy injectors faster than high mileage.

 

They say 200,000 is about the average life expectancy. I started having issues with mine at right around 150,000. I believe there were symptoms prior to that, but they were slight, like a little puff of white smoke on start up and then running a little rough until she warmed up, not terribly, just a little. My father has around 190,000 on his, and is still running great. I was doing extended oil change intervals based on used oil analysis, and I think that it had a negative effect on my injectors. I don't know that for certain, but that is what I suspect did mine in.

 

Ive heard of them going out at 150k and 450k. On time oil changes seem to help them go longer and using good clean fuel. I have 264k on mine. I have some smoke on cold start up but other than truck runs great and gets good mileage. Maintain them and they should last awhile

 

Does the rub do something special?

 

Now that's funny right there...

 

BigAl posted this yesterday and I found it interesting.

I apologize for the rub test haha i wish that worked but i actually meant run tests haha

 

I do extended oil changes based on oil analysis (12-16k miles) and ive got 278k miles on original injectors. No hard starts, no smoke at startup. But i do notice a bit of haze now and then when stomping it to pass another car sometimes, not everytime but sometimes. Still get 18mpg. Im thinking of doing an upgrade at about 300k, but we shall see.

 

You also have a bypass system which should make a big difference, Damon. I do not ever plan on going much past 5,000 mile OCI again. Even though I was getting great analysis reports, my injectors went bad at around 150k, but as they say, results will vary.

 

The bypass was installed at around 180k. Before that it was 5-7k OCI.

 

If you are still getting 18 and dont have and glaring problems....then DO NOT DO ANYTHING TO WHAT YOU HAVE. My truck still isn't as smooth as I like it and I am sure you have read about Tuglys struggles.

 

Yeah... what he said. I've learned 300K is not the time to start amping up the oomph. I just discovered a mildly-leaking valve guide today and that puts an abrupt end to upgrades... now that I'm done upgrading it anyway.

 

I went 250k with no problems. but did religious oil changes , I did mine because I needed to replace the cups
