TGP Z-34 STE Posted July 18, 2011 Report Share Posted July 18, 2011 I am wonder is that common? I dont know what it called but a sleeve that keep valve seal broke off! I am not sure either someone put some metal in intake and go in all 6 pistion. Can see little metal in all of cylinder. only 1 is damaged bad, other is fine. That's why I doubt the valve sleeve is the cause the problem for motor. Since there is one sleeve broke off while other 23 sleeve still good on heads. but find metal in all cylinder. I guess that metal broke off sleeve. But I have no proof yet. Red 1991 STE 3.4 DOHC 284 Getrag.zip Quote Link to comment Share on other sites More sharing options...
