787 oil injection nozzles

[DaddyLoafin]

The nozzles for the oil injection on the rotary valve cover are blocked on my engine. It looks like who ever used this rotary valve last was running pre mix and put something in them to block them. What would be the best way to clear them out? Or is it just better to get a different cover?

Those are check valves. I wouldn't trust them if someone plugged them. Valves are bout $30 each. I test them on every engine. They should hold about a 1/2 pound of pressure and relieve around 3 pounds or so.

Thank you. With the correct name I was able to search and find replacements and pull them out.
