I have the same oil burn on my engine, just went out to check my cap....no gasket! i am going to laugh to hard if this fixes my oil issues. ill try to get back to the thread if it works.

Great thread OP. So many posts on this issue with little commonality.

My AP1 has been burning a qt every 600-800 miles since I bought it with 80K. No change in consumption now at 145K.

So how does one pressurize the crankcase? I have a small compressor at home.

Also, my cap is Mugen so I think the seal is good. Where are some other likely sources of an air leak? I do have some light oil weeping at the PCV o-ring on the valve cover.

After this I realized I had an aftermarket oil cap with a totally different gasket that was torn apart. I just put the OEM one. Will get back with results in a week.

who was giving you grief?

Seemed like the thread was going pretty well and did not see anyone giving any grief really. Maybe some posts were deleted we did not see?

Which makes the whole early circa 2000s theory about replacing your PCV valve more interesting -- it wasn't usually the valve itself per se (unless it was clogged), but perhaps for some people it was the gasket/ring seal that had issues!

For what it's worth, I replaced my oil cap rubber about a month ago after seeing this -- it was as hard as a hockey pick. The new one is softer and the cap feels like a pillow when closing. Still burning oil. Will look into the PCV and dipstick next, however, since the car is 17 years old -- all the gaskets are hard!

Im sorry, it was no one in this thread. I removed all my content from the forum.

But the gist was measure crankcase pressure, it should be close to -11 to -14hg at idle. if it is less, you have a crank case leak likely. check all areas that OIL and AIR are, this pretty much limits it to all gaskets on the valve cover, and front timing cover. High pressure gaskets like vtec or the like, or sump gasket(oil pan) are unlikely to leak significant pressure without there also being a massive oil leak. Weeping oil, and crankcase pressure are what you should look for.

FRM doesn't like to seat rings like IRON sleeves. so maintaining crankcase vacuum is necessary to keep the rings fully seated and minimize oil burn. The original post commented on the similarities of Oil burn being minimized when installing KrankVents. The common denominator between posts on the forum of people minimizing oil burn - crankcase vacuum to effectively seat rings during stroke. Leading to believe the PCV system is undersized, OR since new significant crankcase vacuum leaks have formed causing the PCV to not run as efficiently as Honda intended. Solutions being finding the leak and fixing, or adding an aid(KrankVents) to the pcv system

Again sorry, it was no one in this thread. I simply used a Python script to delete all of my posts across the forum
