Technically this applies to a Volkswagen, but you guys seem to know more about the inner workings of engines than do the import guys. I've been having trouble with multiple oil leaks lately. Now, as far as I know, if the PCV system were providing adequate vaccuum to the crankcase, even if seals were leaking they would at least be letting air in instead of letting oil out (until the engine shuts off, at least). But there are two problems with that: 1. I rebuilt the PCV system myself a few months ago, and I know it's providing adequate vaccuum. 2. When I pull the dipstick out while the engine is still running, I can see a stream of thin smoke blowing out -- not drifting, not wafting, blowing out. So, there's positive pressure in the crankcase, and the PCV system isn't moving enough air to compensate. My engine is turbocharged, but that shouldn't make a difference at idle because the turbo isn't spooling at idle (and the PCV valves are there specifically to keep turbo pressure from making its way into the crankcase, anyway). So something is applying pressure to the inside of the crankcase, even at idle. The only thing I can think of that has high pressure at idle is the insides of the combustion chambers. Does this sound like bad rings to you guys too? 'Cause it sounds like it to me.
