Hercu Posted July 16, 2018 Share Posted July 16, 2018 The 2.7 TDV 6 Disco 3 with new sub and recon heads started and on revving there is a serious knock lik piston hitting the valve Could it actually be a valve hitting the piston or maybe a lazy hydraulic lifter, Injector (Diesel) knock ???? The smoking is from cracked return coupling and was fixed but the problem remained TDV 6 2.7 above 2000 RPM.mp4 Quote Link to comment Share on other sites More sharing options...
