Hi everyone: I bought a junkyard engine in anticipation of buying a Vanagon that had an engine fire (though the purchase of the van might not go through) and I've been slowly dissasembling the engine. I suspect this engine is not too old in terms of miles run (it's a VW Canada rebuild) but I think it may have been run with some extremely dirty oil. Anyway, in looking at one of the rocker arm shafts I've pulled, one side of the shaft (where the rocker arms ride) is shinney and worn, while the other side remains untouched. I didn't pay close attention when I took this apart so: 1st question: I would guess the shinney side of the rocker arm shaft is the side that was *toward* the top of the head? (As opposed to the side that was toward the valve cover.) In looking at this shaft, the worn side has some gouges, big enough to "hook" a fingernail on, that look like the result of dirt in the oil. The inside of the rocker arms, however, look fine. So: 2nd question: Can I "flip" the shaft when re-assembling, putting "unworn" side of the shaft toward the head? (Assuming the answer to question #1 in "yes.") In looking at the holes in the shaft that the head studs go through it looks like one side of the holes have a slightly larger "bevel" than the other side, but I can't see that would make any difference in performance. Thanks for any help. --------------------------------------------------------------------- Tom Young young@sherlock.SIMS.Berkeley.EDU Lafayette, CA 94549 '81 Vanagon --------------------------------------------------------------------- |
