I am pulling my cylinders this week for new pin plugs and new rings (engine started making more aluminum again - it had tapered off, but is back again). I looked at the parts diagram for my O-320B1A and it shows through studs that thread into the right case half. However, I have read that there is a mix of those that thread into the block and those that don't. It is a different procedure for tightening the nuts on the through bolt, so would like to know. I don't rememeber paying attention to this on the overhaul.
I am guessing that I will be able to see if the case is threaded when I pull the #3 cylinder, but not sure.
I would appreciate any tips or advice on this. For those following my oil temp issue, I have determined that I am getting at least moderate blow-by, which may be contributing to my temps. Compressions were all around 70 and the oil from my last change 3 hours ago is already turning brown.
I was able to get everything striped off the engine today and will pull the jugs when the new rings get here on Wed.
