But assuming I have one, and that your change helps the situation, what is the indicated or implied issue?
That oil/vapor is being pushed through PCV and cycled into intake manifold and getting burnt off? Is plugging it considered a fix, or just a diagnostic step?
Just want to understand, thanks. |
A PCV that sucks a large amount of oil is not an uncommon situation with FEs. If you really are losing a quart of oil for every 200 miles or so, and you don't have a big puddle on the garage floor, then it can only be disappearing for a couple of reasons. The easiest, simplest reason is that the PCV is sucking it in. If pulling and plugging the PCV, as a test, makes the oil consumption go away, then fixing it is relatively easy. You can then either: 1) Remove your PCV entirely; or 2) Baffle your valve cover on the PCV side. you might also add a nicer PCV valve, like the ME Wagner, along with an oil air separator. But if plugging the PCV as a test does nothing to the oil consumption number, and it really is about 1 qt. every 200 miles or so, then you'll need to look elsewhere. |
