"We got his injectors in and inspected
Prior to any cleaning we test fired all four injectors. All four fired exactly at new specifications with every orifice spraying in a uniform spray pattern.
Due to normal carbon discoloration as well as combustion deposits (usually burned oil residues) we removed all four nozzles and ultrasonic cleaned both nozzle and needle.
During removal we noted the needle tip condition, all four showed perfect sealing and no combustion ingress from clogging or internal contamination.
After cleaning all four nozzles we reinstalled them on their respective injector body and retested to determine any post cleaning changes in nozzle response. All four fired exactly as removed prior to cleaning with uniform atomization and dispersion distance from nozzles.
We noted that one nozzle had “splatter” residues on the nozzle cone. The splatter residues did not occur in a location that would have prevented the nozzle from spraying correctly. The spray pattern remained uniform and all 5 holes atomized like new with new ejection characteristics.
Although the nozzle appears to function as new, we replaced it since the splatter could cause a hot spot with continued use possibly reducing the nozzles potential life.
All four injectors are cleaned and tested, ONE nozzle (BSLA-150P-764) was replaced and verified to match the other injectors.
No changes to any settings were required, and all are within new injector tolerances.
