Hi, I've been lurking these threads for some time, but I can't seem to find much on this particular R18 leak. I'm losing about 1/2 quart to 1 quart between oil changes. The leak is on the front of the engine. I'm not too familiar with all the components here but can anyone tell what/where the most likely cause might be? I thought it was the infamous block crack, but wouldn't that be coolant instead of oil?

Thanks for any help!

That's the oil pressure switch below the block heater. Oil pressure switches almost always leak eventually. Just unplug the cable. Unscrew the switch. Get a little gasket sealer and apply to the threads and snug it back in there. Straight forward but a bit tight to work on.

Thanks! I picked up some Hondabond HT and cleaned everything up. Hopefully it stays that way!
