ok, well I have no leaks, but I do have injector noise that stays with the cylinder. I'm thinking prechamber or maybe one of these seals.
But no leaks means I should leave it alone? |

No leaks generally means leave the IP alone. The injector noise could be a spray pattern issue... I'd pull the injectors and have them all pop tested. Prechambers almost never fail so it's extremely unlikely that's an issue unless the noise is severe. You can do a visual inspection to verify the spherical pin is still present in the prechamber. Another possibility is an internal IP problem, but changing the DV seals is not likely to cure this. It wouldn't hurt to replace them for grins, but don't be surprised if that doesn't fix the problem.
BTW - it helps if you update your profile with the year & model of your car, so we know what engine you are discussing... ![]() |

When I used to rebuild Fuel Injection Pumps the only time a delivery Valve Spring was replaced was if it was broken or had some issue that looked off when you looked at it.
We did inspect the Delivery Valves themselves to see if they were worn. However, in this case you are better off leaving it along; I don't recommend pulling up on the Body of the Delivery Valve as it can pull up the Element Body. He could use Viton O-rings and He might not have to change them again.
