[QUOTE="ROKRIG, post: 1243416, member: 18487"] Valve ticking from passenger side of motor ('89 4.3 v6), used but rebuilt motor from Derrick (Deerlick). Just trying to eliminate the ticking which Derrick also confirmed was there when he had it and that he just didn't get around to adjusting the lash. Anyways...I've eliminated the ticking. My only problem now is that it runs rough (like it's got a really aggressive cam in it). I think this is because I slightly tightened the loosey goosey #6 exhaust valve on the #4 firing position in addition to having done it on the compression stroke. I'm going to go back to compression stroke, double check the lash on that valve and let it be loose on the second revolution hoping that the oil pressure will take up the slack and all will be good. Thank you all for your input. I really do appreciate the varying methods. Terry [/QUOTE]
