So prior to removing the heads I need a tool, "Camshaft Positioning Tool". From my understanding all this tool does is lock the cams in place so that the cams aren't turned improperly leading to timing issues and various other problems, bent valves... etc. Well I'm still thinking this is a long shot and chances are I'll end up purchasing the tool anyways. Thing is I need two @ almost $40 ea. and it would take 5-10 business days to get here.Anyone think it may be possible to fabricate this same tool on my own? All the tool is, is a straight bar with keys that fit into the rear of the cams.
