    Those do look nice, but I have heard just about zero feedback on them… just out of curiosity, what is the weight, compared to a standard throw-away filter?

    Damn man, that’s painful to look at. Looks like all crippled laying in the corner like that. Wish the bike a speedy recovery. Heal well. Next time store it in a bubble wrapped room.

    Is that the breather tube from the airbox?

    So fill in the holes, Derek, did you have a get off? If so, was the get off likely caused by the oil on your back tire, or was the oil leakage after the tip over?

    So @jnsracing the oil just started coming out from the breather tube while riding home… I luckily didnt lay her down as I did drift a left hand turn from a stop sign though… and once i got her home i pushed it into my storage and was moving it around as i tripped and lost my footing and down she went… :coverface:

    That makes me sad… very sad :( .

    @cbr-f2 – I am far from an expert. Curiosity is what drives my question. Is it possible the oil filter was the cause of the leak? Just wondering if there was evidence of oil on or around the filter once you removed it.

    I am just as curious as you are @94f2-08rr … The oil is coming out of a breather tube, but I’m not sure from where it comes from yet… No actual leak from the filter or anywhere else… I am thinking it does have something to do with the re-usable i just tried out… So my next step to do is swap back to a GENUINE Honda oil filter, trace the breather tube and clean up the oily mess…

    Since this just occurred after an oil change, my first suspicion would be that you might have overfilled the oil a bit.
    There is a breather tube going from the engine to the airbox, for balancing crankcase pressure, and purging built up gases in the crankcase to the airbox, to be burned in the intake charge – most of the time, the cause for this kind of leak is excess oil pressure, due to there being too much oil in the system, and it escapes through the crankcase ventilation system… I would take off your tank and airbox, and see if there is a lot of oil still sitting in there, and of course, check your air filter, as it can get saturated, and not flow properly.

    Another thing that can cause this, is excessive blow-by at one or more piston rings, which allows for an excessive build up of pressure in the crankcase :mouthopen: , once again sending oil into the airbox via the ventilation hose… hopefully it’s just the former! 8)

    On the oil filter, hopefully, if it’s designed as a replacement for the F2, the element would be of the correct flow properties, so that oil can move through it as normal, but I suppose that if you know that your oil level is correct, and still get leakage from the airbox, it’s possible that the filter is NOT allowing the oil to flow as it should, and is causing an issue with pressure build-up.

    So last night i got the bike torn apart. Traced the hose and turns out to be the coolant over flow tube off of the coolant resivoir… So this means i have oil in my coolant… So next i drained the coolant and sure enough there is, oil in the coolant. Wtf!?!?! Pulled off the oil filter and drained the oil and no coolant is in the oil… ? So i am suspecting a seal or O-ring has failed/let go in the oil cooler… I also pulled the air box cover to look inside and looks ok…. What to do what to do???

    @cbr-f2 – I’ve been wondering if you had the opportunity to search for your problem(s).

    You are most likely correct, with suspecting the oil cooler – this is the most common point for oil to enter the cooling system, due to failed seals.

    Assuming the core is fine, then what you’ll definitely need are the two O-Rings that seal the core to the cooler base, but it would be foolish to not replace all the seals while you’re there – you could try to re-use some items, but how frustrating would it be to be ready to go back together, and you find that some of the other O-Rings are also bad, and then you have to wait for parts! :-x

    You’ll also need, in addition to the aforementioned seals, four O-Rings that seal two separate collars, that join the lower portion of the oil cooler base to the block, one larger O-Ring for sealing the upper portion of the base to the block, and the gasket that seals the base to the cover… all told, you should only spend about $20 for all of these items.

    Good luck Derek, and keep us posted!

    Well @jnsracing … I have already ordered all 8 seals and o-rings, but at honda they cost just under $40. So i am thinking if i try to confirm my suspicion… Is to pull the cover off and attempt a short dry fire of the cooling system and hopefully see my oil leak. I really do hope this is just a failed seal in there… *fingers crossed!!!* :cry:

    That sucks! I’m talkin’ about the price.
    At my Honda dealer, I usually pay right at, a little under, and sometimes just a smidge over, the cost I calculate using RonAyers.com’s parts fiche… maybe they are giving me a discount that they’re not telling me about.

    Hopefully replacing all those seals will resolve your issue. :socool:

    i hope so too… i did seal one end of the oil cooler and blew some air pressure to see if it has a hole, there wasnt so thats a good thing!

    We just did a coolant change on your bike and mine. I wonder if the water weter had something to do with it. Old seals look bad but also strange coincidence to have just done your coolant with water weter. Just a thought. How’s the progress?

    So I know its been a while, so here is an update… I finally got all the seals for the oil cooler along with new header gskts… all put together and installed, flushed out the cooling system and radiator of oil along with the resivoir…


    also put a new filter and oil in… again :crazyeyes:
