close one!

Hey guys,

I popped my valve cover off after about 20 minutes of driving to adjust the valves. When I popped it off I saw that the oiler bar closest to the #6 cylinder was so close to one of the lobes of the cam I could almost fill the gap with my thickest feeler gauge! I took the oiler bar off, I knew it was bent but further inspection would reveal much more...

When I unscrewed the bolt that held it in, it was off center, meaning the bolt were bent a bit... Then I pounded the resevoir part of the oiler bar assembly back straight. and then got as close of a fit as I was going to get.. When I put the bar back in I noticed when I tightened it even a little it still pulled to that side. I finally looked very closely and I think the part of the rear cam tower that has the threads in it for the rear oiler bar was warped a bit... or somehow bent back ever so much... This may have just been because I could not get the screw perfectly sstraight, but it may have been the cam tower. Anyway I did not adjust the valves because I bought some new non slip wrenches with little lips on them, and they would not fit like I wanted them...

Anyone ever heard of this or know what might be going on?

Also anyone know a good way to get the left over goo and gunk from the carpet off the interior?

I experienced similar problem on my '71 but didn't catch it in time and the lack of oiling destroyed the cam lobe for the #6 exhaust valve and its mating rocker arm. End result was a very annoying tick due to the scored surfaces. It was caused by failure of the braze attaching the cantilevered tube to the distribution block. You may have the same problem and suggest you carefully inspect the braze joint. A bent distribution manifold may also be the driver. The solution is to replace the manifold immediately since it is alot cheaper than replacing the cam.
