Injectors with engine replacement

sanny651 · May 20, 2025

Hey all, does anyone know if they replace fuel injectors when they do a 6.2l engine swap due to seizure? Bringing my truck in just to have them give it a once over before my factory warranty expires and my aftermarket warranty starts. I was going to have them perform a fuel induction service, but if the injectors are new with the engine (4k miles ago), then I'll hold off.

I don't know. But, I would say no. The reason I give, is injectors are not included in a long block replacement. Which is what I would imagine gm is supplying.

It could possibly be a short block, but I haven't heard what gm is paying for book time. Bet not much, so gm wouldn't be paying dealer to swap over heads, if'n there was a possibility of valve strikes.

I know when they replaced my engine, they replaced the oil cooler, intake, battery, and I BELIEVE the radiator along with the engine. Just wasn't sure if they replaced the fuel rail components as well or not.

Ultimately wondering if I should pay for a fuel induction service or just run some of the GM fuel treatment additive and call it good for a spell.
