Adam_M Posted April 22, 2013 Share Posted April 22, 2013 Hi everyone,On my Honda CBF 125 I seem to have engine oil leaking out of the left hand side of the engine. Originally this was coming out of the nuts and bolts but after doing an oil change (I'm guessing it was too high pressure wise) it seems to be coming out of other places now!I'm going to guess I've blown something, somehow. Hopefully I haven't blown the engine, any ideas? I'm hoping I don't have to buy a whole new lump for it...Tomorrow I'm going to do an oil change again, this time put less in - this was my first ever oil change so I might have buggered it even more. (but hey, I'm trying to learn and I'm very new to this! computers I -can- do, engines... not quite clicked yet)The bike seems to be performing just fine, It only seems to start leaking after it's been going for a while or I hit a 60mph section.

rennie Posted April 23, 2013 Share Posted April 23, 2013 Very difficult to diagnose without seeing it!If it's just overfull it should come out of a pipe or somethingnot the engine.Sounds like you've blown a gasket to me. Quote Link to comment Share on other sites More sharing options...
Bogof Posted April 23, 2013 Share Posted April 23, 2013 Tomorrow I'm going to do an oil change again, this time put less in - How did you check the oil level when you refilled it after the oil change? Quote Link to comment Share on other sites More sharing options...
Voodoo Posted April 23, 2013 Share Posted April 23, 2013 If its covering your side stand or coming out of the sprocket engine cover it could be excess oil from your chain. Quote Link to comment Share on other sites More sharing options...
Fozzie Posted April 23, 2013 Share Posted April 23, 2013 You should only be using a litre of oil or so...Just 1! But check your manual, I've not known a 125 use more than 1 litre when it was just a single cylinder.Upload a picture and I can tell you what it is Quote Link to comment Share on other sites More sharing options...
Tango Posted April 23, 2013 Share Posted April 23, 2013 Blocked crankcase breather? Definitely check the level as suggested above...... Quote Link to comment Share on other sites More sharing options...
Adam_M Posted April 24, 2013 Author Share Posted April 24, 2013 Well... I did the oil change, and about 1.2L came out of it. If you estimate that 15-20% is still left in there then that's way, way over! max capacity is 1.1L... suggested change is 900ml... ouch. The poor thing.I've now put in the correct amount, and it's not leaking as bad but I'm going to have to man up, buy a Haynes and some tools and fix it myself. Had a mechanic guy at work look at it, looks like it'll be all okay as soon as I get the gaskets replaced.It was a dumb, newbie mistake and all down to impatience. I think when I last topped up the oil I didn't do the dipstick reading properly (the whole, let it run and then leave it a few mins to settle cycle) Ah well! this is how we learn right?!

Cc030100 Posted October 17, 2022 Share Posted October 17, 2022 I have the same issue, oil leak on left side cylinder head area after oil change but apparently they only take 0.8 litre so I was thinking over fill but my leak is quite dramatic so not sure.I’m also gonna change it again Quote Link to comment Share on other sites More sharing options...
