turbobluestreak Posted July 16, 2003 Share Posted July 16, 2003 ok this is really p!ssing me off. I just put my head back on and I'm sure that the cam journals are back in there orginal location, but I can't get it in the journals, so what could be wrong? wraped cam, wrong aliminmant, wrong placement of the journals? What do you guys requimend that I do? tbs Quote Link to comment Share on other sites More sharing options...
Cruez Posted July 16, 2003 Share Posted July 16, 2003 Are you trying to put the cam in with the towers already torqued in place? Quote Link to comment Share on other sites More sharing options...
turbobluestreak Posted July 16, 2003 Author Share Posted July 16, 2003 yah, oh sh%t I take it I wasn't supposed to do that. well I guess I just shot one head gasket to heck. tbs Quote Link to comment Share on other sites More sharing options...
zcarnut Posted July 16, 2003 Share Posted July 16, 2003 Yeah. The key is to install the cam AND towers together. Then go in steps when torquing the bolts which secure the cam towers to the head, so all the towers are torqued evenly. Start with a low torque setting, and increase the torque setting each time, all the time checking for smooth cam rotation. If necessary, tap the towers with a rubber mallet to smooth things out, then repeat the procedure until the cam tower bolts are torqued to spec, and the cam turns freely. Since the head gasket was not exposed to any combustion chamber gases you can re-use it. I would just add 5 ft-lbs of additional torque to the head bolts to further crush it. I have know several mechanics who have used this "trick". Quote Link to comment Share on other sites More sharing options...

turbobluestreak Posted July 17, 2003 Author Share Posted July 17, 2003 all right I didn't pull the head just the towers, I got it all reinstalled and timing set. Thanks for the help guys, it's late so I'm going to finish my motor tomorrow and will be that much closer to being able to drive it again. tbs Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted July 17, 2003 Share Posted July 17, 2003 You did not have to go thru all that trouble. You could have just loosened the cam towers, installed the cam, and then retorqued, ENSURING it spins freely. A day late I know. Quote Link to comment Share on other sites More sharing options...
