Default Injector Shelf Life?

I have a set of SVO #30s that I pulled out the car 10 months ago, are they still worth putting back in or are they bad? Thanks

They should be fine. Having them refreshed is a great thing, but why until you know they are bad?
Having said that, if there is any peanut butter paste involved, get rid of them.

How do you know they are good? Speaking from experience, I sent a good set of Bosch 36's for FIC restoration service. The injectors had 500 miles and sat for 1 year. 7 needed new filters and cleaning while one was leaking and had to be replaced. I wouldn't install a used set of injectors that have sat for an extended length of time.

Injectors that sit open to the elements will absorb moisture etc. moisture causes rust on the internals of certain types of injectors. A leaky injector can hydra lock your motor. Aarons injector leaked while doing an extended pressure test at 70-100 psi. It was a drip but, enough to warrant a replacement. When we sell injectors we fill them with a special lubricant and seal both ends with a air proof cap. This extends the shelf life. Yrs ago certain new injectors were packaged in a plastic tube filled with a light oil. the injector was submerged untill used. Shelf life deterioration has always been a problem,

Sorry for your experience, Aaron. I repeat, I would test first, versus pizzing $90 down the drain.

My parents operate a salvage yard and we often sell pull-out engines that have been sitting on our racks for years. If we get a car in with a bad motor, we'll take a used engine off the shelf and put it in ourselves. I do not ever remember having an issue with injectors. I wonder why this is?? Maybe stock injectors are more durable or something? (as opposed to aftermarket and/or high performance injectors)

those injectors probably had fuel left in them, keeping most of the mechanical parts sealed from the elements.

Or they were leaking and you just didn't notice lol. Its a tough problem to pick up on

that should be fine. When I take an engine apart and the injectors are out i always get a coffee can with some fuel and keep them submerged until I put them back in. This way I won't have to worry. The pintle valve in the injector only opens a few thousands, so, any dirt or carbon can make them work improperly.

Honestly, for you I would recommend new injectors. The SVO (Bosch design II) while a good injector, isn't the best option for the LSx or LTx cars, because its wide spray pattern is designed for 4v engines.

I would recommend our Bosch Design III in 30lb for you. The spray pattern is MUCH more suited for your engine (the Design III is the stock injector in an LS1/6). And since its your DD, you will notice better startups and mileage with them, since you wont be getting the fuel wash.

I can do the Design III in 30lb, flow matched, viton o-rings installed, and a 3 year no questions warranty for $189.95 for the set of 8.

Rich,

I have an LS1 and have the stock injectors, so shouldn't they be the Design III?

Also, I think mine are 24lb. If so, does that mean I will have to get the ECM reprogrammed for the larger 30lb injectors? Sounds like a pain in the butt - I already have an LS6 intake manifold and the 6.0L heads. The Camaro tune on the ECM is going to have enough trouble keeping up with those mods, let alone a different injector size.

What do you think?
