First off, thank you to the site and members. Owner of an 07 Odyssey for two years so I've been lurking for awhile. It's time to do my TB and with what I've read I have the Aisen package and am ready to tackle it myself. I did an oil change myself two weeks back and then drove road trip 300 miles up into the mountains. I lost/burned 1/2 quart of oil. Looking underneath the engine, the leak is either my crank seal, or oil pan/oil pump. Since I will have the timing belt off, I will replace (hopefully) just the crank seal, if that is where the leak is coming from. Obviously I won't know until I get the timing cover off.
Here is my question that I have not been able to find the answer to, either here or the rest of the internet. 1/2 quart of oil in 300 miles seemed excess especially since this is a new leak. Only 78k on the car. I am wondering if I have a bad PCV valve, or associated hoses, so since it is cheap, I'm I st gonna replace it. A bad PCV valve can cause the internal pressure of the engine to rise, causing leaks. Makes sense. But nowhere can I find if the leak is just temporary due to increased pressure, or once the seal starts leaking, the seal/gasket/ o ring is definitely shot and just needs replacing?
