Howdy y'all
Over the weekend I finally got around to replacing the PCV system on my 91 wagon. The engine has over 300k on it, and was suffering horribly from overpressure. That said on my first test run around the block post install I noticed a huge cloud of smoke, which upon further investigation I noticed ~1/2 qt of oil that seems to have come from either the headgasket or rear main.
The car runs fine, doesn't overheat and never leaked from these areas before. The smoke itself was from the oil burning off on the exhaust manifold and downpipe. Is it possible the change in pressure could've pushed some seals over the edge, or is this just an old fashioned case of user error?
