Fuel injector service.
« on: Today at 07:09:35 pm »
Well took the day off to tackle the fuel injectors. They have been in the back of my mind for a while, as been seeing lots on how the filter baskets start failing and cause running issues.

Bought elring seals, stainless mesh baskets from AKS and I have the injector seal fitting tools already and went for it. I had carbon cleaned the inlet valves about 5 years 20k miles ago and was also curious to see how bad they had become, if at all.....they were really bad the first time I did them.





After striping it all down and removing the inlet manifold, I was surprised as to how much carbon had built up again....but not as much as when I first did it.








Injectors were dirty so soaked and cleaned with a tooth brush the heads





Removed the baskets which were also dirty and falling apart. Caught them just in time.











Cleaned the inlet valves to about a 90% clean state....after and before.






Flushed the injectors out using a can of carb cleaner connected to its pipe and then into a tyre valve. Used a 9v battery to cycle the injector on and off until a fine mist was produced.




New seals fitted to injectors and manifold





Put it all back together, primed a couple of times and she fired straight up..... thank the lord LOL

All good and no leaks, but will monitor how she drives and cold starts.
