I'm not sure what the official report on cracks in the precups is but personally I would get the injectors checked and carry on. Your cracks don't look too bad from what I can see.
If this is a high performance engine I would definitely replace them. Giles can get the 1.9 precups.
I'd concur, fwiw... unless you're intending to fuel the heck out of the engine I'd say get 'er decked and away you go.
I would tend to agree. I had cracks like that and I replaced mine. However if I hadn't planned to run it hard, I'm not so sure I would have changed them. They look like they are tan, in my opinion Inconel or some type of nickel alloy which are superior to what I got to replace the ones I had. Just my 2 cents.
Thanks for the input, the engine is all stock fuel/boost levels, with that in mind we should be good to go then.

Yes, granted the injectors are in fact NOT actively destroying them. Perhaps have the injectors pop and spray tested. Any truck shop can do it.
I had mine checked for free at a big rig shop. They didn't give me any numbers but they said "yupp popping within range. spray okay"
Getting them pop tested is no issue theres a local guy who does it.
