DCZ Posted September 13, 2010 Share Posted September 13, 2010 Noisy hydraulic valves have been driving me crazy so I spent some time this weekend pulling the lifters out and cleaning them. *Thanks to Cygnusx1 for the excellent write-up on this subject*. I noticed that my rocker pads are all worn so I'm going to send them off to get them resurfaced. Do I need to mark them so that they can be put back in their original positions? I understand it is normal practice not to mix-n-match valve components due to the wear patterns, but since I'm getting these resurfaced, it doesn't seem like I should worry about matching the rocker to its original valve. Is that correct? Just wanted to get some expert advice before I mix them all up! Quote Link to comment Share on other sites More sharing options...
josh817 Posted September 13, 2010 Share Posted September 13, 2010 (edited) Uh I think the same "don't mix and match" thing applies even if they are resurfaced. What I'm trying to say is that if you resurface the rockers, that wear pattern which matches the cam lobe supposedly, will now be gone. So you're putting a clean slate in while the cam isn't so... "clean", if that makes sense. Another words I would assume you would have to get your cam polished if you resurfaced. Cam/Lobe used/used = ok new/used = not ok used/new = not ok New would mean resurfaced, polished, or flat out brand new. Used, obviously this would mean used within the same motor, matched sets, so I can't get buy a used cam and then mix it with rockers I already had. Although I'd like to disagree with the no mix matching thing, I don't have any first hand experience concerning whether or not lobes go flat or rocker surfaces get chewed up. When I think about it though, I believe I used rocker arms from a spare head with a new cam, and have not had any catastrophe... knock on wood. My luck is probably coming to an end. I've put maybe at most 7000-8000 miles on the motor. Edited September 13, 2010 by josh817 Quote Link to comment Share on other sites More sharing options...
DCZ Posted September 14, 2010 Author Share Posted September 14, 2010 Thanks for the reply, I'm not sure on this one either. The cam lobes look good - no wear or discoloration as opposed to the rocker pads which have a distinct groove worn in them. I'm hoping one of our resident experts will chime in. Maybe this is one of those "maybe, maybe not, do at your own risk" situations. Quote Link to comment Share on other sites More sharing options...
