New oil filter keeps leaking

[flanagaj]

I fitted a replacement filter at the weekend and it just keeps leaking. Firstly I did it hand tight and then I tighted it further in stages until the filter started to dent. And it still leaks. I cleaned the oil filter housing and put a smear of oil on the filter rubber.

The filter did look like an cheap unbranded thing (ordered on my behalf). If I do have to take it off can I reuse the oil ?

Not having a lot of luck at the moment mate are you, you dont need to drain the oil to take the filter off just undo the leaking filter and pop a new DUCATI filter back on and top the oil up again

dont forget to fill the filter up with fresh oil as best you can before you fit it........saves a moment of pumping fresh air around the oil galleries.

[stu 748]

Good idea Andy i didnt think of that

You are not wrong there. I have no problem servicing my mountain bike, but this baby keeps given me hassle.

Should I go for a genuine Ducati filter ?

[ath748]

Genuine Ducati part only costs £7. Hardly worth the risk of not really....

[Albie]

Yes for sure use genuine parts like filters or very good known alternatives. This is the bit of your engine thats stops crap going round it.£40.00 + for oil and filters a fiver or so.:smug:

My bike is a y2k 748 yet some sites list a 748 and 748BP. Will the oil filter be the same regardless ?

[stu 748]

Spot on guys i wouldnt put anything other than a genuine oil filter on my bike, but persivere with it flanagaj you wont be dissapointed when you get her sorted

[stu 748]

My bike is a year 2000 748s and i ask for a 748 bp filter hope that helps

Get in touch with Nelly at cornerspeed and get him to send you one down then you know you have the right one

[rockhopper]

I think all the filters are the same. Nelly will sort you out anyhow.

i had the same prob (genuine filter though) after filter and oil change it just kept leaking
didn't have time to change it till the next w/e so just kept an eye on the level
by the time it had got round to the following saturday it had cured itself

Genuine filter schmilter! use crossland's on my bikes,£2.65p same spec' as standard never had a problem,if bike leaks after change,just nip up by hand while still hot,remove filter with warm motor when time to change comes around,NO PROBLEM. Steve R. cornwall

When you fitted the new filter, did you smear a little oil on the o ring seal before fitting. This helps lube the seal when you tighten, rather than it being dry and gripping!

That is very important - you simply cannot tighten a filter properly if the rubber seal is dry.

Ditto.
I've lost count of the number of filters I've changed.
I just buy 2 or 3 from whatever supplier I see when I need them.
Sometimes they are ducati, sometimes not.
Never had a problem, cos they are always changed before they get to a tenth of their design life.
(Just think how hard a life these parts have to be designed to take, and then consider how often we change them !)

2nd or 3rd'ed or whatever. Both my bikes leak even if I do replace the washer unless they have grease on them.

Not just a question of design life though, it's design quality and more importantly in the case of filters, filtration level!! Half of these so called after market filters aren't good enough for a deep fat frier yet alone a highly stressed modern engine. Stick to known brands or OEM unless you know the manufacturers design specifications.
Systems not to skimp on; Brakes, Suspension, Tyres and Oil!

A genuine Ducati filter is only about £6, hardly worth any kind of risk associated with a non Ducati item for that kind of money i would have though.
