DGP Posted March 5, 2020 Report Share Posted March 5, 2020 I have pulled apart an L4 compressor changing a scroll assembly...this thing was absolutely filthy...and it was still making the numbers. The 407 that I was flying that was temping out did not have the bypass light on for the air intake...I opened the doors for the bypass to see if this would help ....sweet f@@k all...still running hot...I can't see a dirty compressor having any effect on the temps or a dirty filter....That L4 had a #1 seal leak that was blowing a ton of oil thru that compressor and the dirt in that thing was unreal!

DGP Posted March 6, 2020 Report Share Posted March 6, 2020 This engine had a bled valve coming due in less than 100 hrs...probably was the problem...I wasn't around for the fix. Quote Link to comment Share on other sites More sharing options...
