Preach on brotha..Enjoyable sermon. Can I get an amen?Wow expensive mistake, sorry to hear that. What I can add is that the camshaft cap is machined from the factory to adhere to the specified tolerance between it and the camshaft journals. Salvaging spare caps is a crap shoot in itself. If you manage to salvage spare caps, you gotta check for clearances that are within the specified tolerances, (section 5-20 in the service manual). If the clearance is below the specs, then you could hone the cap using a lathe. You'll have to find a machine shop to do this for you. Conversely, if the clearance is above the specified specs, you're back to square one. But the best solutions are to salvage a complete head or buy a new one.
Get a good quality torque wrench. Get both a clicker and beam type torque wrench to compare accuracies. Especially in these critical engine components.
To get the proper torque values, those cam cap bolts require a dry torque. Meaning the bolt and screw holes must be dry and clean. If the threads are wet (oiled) then the torque figures will be roughly 30% more than what is required. Be sure there is no residual oil on the bolt threads and screw holes. Spray 'em down with brake cleaner or a degreaser. Unless specified by the service manual, always clean bolt threads and holes before torqueing. Always torque bolts in the specified sequence for an even force distribution and to minimize warping.
Didn't mean to preach, some tips that should help you out. Good luck.
