I've got a '76 Series III Land Rover like that... I've changed the oil several times, without ever undoing the drain plug

johnk8080 There is a drain tube on the bottom of the air box. On the bottom of the tube is a "bulb" that fills up with excess oil. Drain that and you will not have oil in the airbox any more.

CheapBassTurd DanJaw,
It would be more pronounced with the pcv mod than without.


The pcv valve will prevent backflow into the crankcase where it can only go up the tube on the next downstroke of the piston.
Leaving the only place for it to end up being the airbox.

As for the other question:

Ride with the cap off for 15 minutes.
(wear disposable pants and socks.) LOL
There should be a good misty blowby on your
right leg at 85+ mph.

A coupla whheelies will help expedite the process
quicker. (or not, I made that up.)

What kind of Honda are you talking about? Dual-sport as well? What year/model?

That, amigo, is genius. I was already planning on making a syphon out of taped together straws. This way better. Thanks dude.

ScareCrow Next time put the filter in a rag after oiling it and step on it. That really gets the excess out. Then if the oil puddle reappears it is coming up the crankcase breather tube that vents into the airbox. The PVC mod can help prevent this but it can still occur if the crankcase is overfilled or you ride looooooong wheelies. A quarter size puddle is no big deal. To get any excess oil out of the motor you could take the filler cap off and tip the bike over on the right side and let some drain out. A bit messy though.

I don't have the PCV mod...still make sense? And here's the next complication. If it is just overfill (which I really think it is), then how the hell do I get the extra oil out? Normally I would just loosen the drain plug and drip it, but I got teflon tape, a new crush washer and almost brand new oil. No way will my Mother in law let me drain all the oil. Drip it from the filter cover? Is that even possible? Let it burn off (god bless the Gen2)? Is that gonna screw me up pressure wise?

Been working on my Honda today, too. It's old, but shit, the rubber is better than on my KLR and it's 38 years old.
