I ended up pulling the valve covers and will be re-gasketing them as well. I also found 2 of the exhaust manifold studs were broken off on the driver's side.... That won't be fun.

Damn man that sucks... how many miles does your truck have on it?

I'm at 213k and haven't touched the injection system once. I've replaced everything else but haven't had a single issue with injectors.

Knock on wood.

Bought it with 135k, has 154k now. I'm willing to bet yours were replaced at some point before you bought it.... i would be amazed if a set of multitechs lasted that long.

Also this is vortec 454 3 of 3 i've seen part and had the beginning failure of the intake gaskets.

Is it normal for 454's to go through injectors like that?

The OEM injectors were Rochester Multitech style... they fail. I have now had this intake apart 5 times, and this will be the 5th set of injectors. The first two sets of injectors were ebay "refurbished" sets, which were a total joke and didn't actually work. i lost money on both of those. Then I bought a good set of LS1 injectors and they ended up being the wrong flow rate, so I bought the Five-O-Motorsports set with a 5 year warranty. Those I've had for a year and work flawlessly.

This time it's apart to do lower intake gaskets, valve cover gaskets, and upgraded injectors.

Well i bought my truck at 140k and i haven't touched them, haven't had any issues with them. I seriously doubt they were replaced, but i could be wrong. Intake Gaskets on these motors are also weak points.

Only issues i've had were the distributor cap and fuel pump. For 213k i'm pretty lucky. Again knock on wood.

I've worked on 3 other 454s... 2 of the 3 other ones had injector issues. Mine and a 5 speed dump truck haven't had any issues. It has 80k, mine has 213k. The other two have around 130k and both have the typical injector issues.

Hmmm. The LS1 injectors were too much, the current ones aren't enough... What is Goldilocks planning?

Yours had to have been replaced by now. I could see the 80k ones still being original, but not 213k.... If they were I would put them in some sort of museum. Any chance you have looked at the color/size/shape of the body on them?

I.... I've said too much already.
