Oil filter leak GSXR 1100

[Joseph]

Hi

I've done a search but really can't figure why i'm getting oil seepage from the filter

The engine surface seemd clean, dont know whether i overtightened the filter ? But i dont think so

Really annoying that such a stupid job is keeping the bike off the road

Check if there is the an old or previously overtightened o-ring present ...as in fused to the engine side. It almost looks if its meant to be there but is not.

 

You need to see bare metal on the spin on part for your new oil filter.

Brand new oil filter, right? Did you lightly oil the outer edge of the sealing ring? How tight did you tighten it?

[Gixer1460]

Strange as I don't think i've ever had a spin on filter leak! Fill with oil, lube the o ring, clean the case face, screw on hand tight - job done! Even had over tightened ones with filter case metal touching case face - no leaks!

[Joseph]

No seal left on the block, i tightened it as per the haynes, hand screw till contact then 2 turns (almost)

A mate mentioned the leak may be coming from higher up, i need to check the cam cover and oil return tubes, the engine being black and me working underneath yesterday evening i may have missed the oil is just dripping from the filter giving the impression that its at fault

I'll have a look and keep you posted

Could well be - have you serviced the valves / tappets recently as those seals on the cam cover are notorious for getting misplaced and oil leaking down the plug holes and out of the well drain hole!

[banoffee]

Clean off all the oil with brake cleaner and compressed air or degreaser and wash and dry it. Then run it up until you find the highest point it’s coming from. Could be the oil tubes on the front or the rocker gasket but best to diagnose it properly.

Hey

Right well so far i have done the following

- removed filter to check mating surface condition. Looks fine.

- checked for seepage at the return tubes, top and bottom. Looks dry

- checked beneath the exhausts at the drain hole area. Looks dry

- removed the plug coils, checked in the plug well. Looks dry

- checked the edge of the rocked gasket qll round, looks dry

- checked cylinder to block and head to cylinder surfaces. Looks dry

Stumped

There is a folded edge on the filter... maybe that is leaking?

[Captain Chaos]

What kind of filter? Original Suzuki, or some inferior copy?

[Dezza]

"Hand tight, then 2 full turns" sounds like overtightening to me. Something like" hand tight, then 1/4 to 1/2 a turn" sounds the way I do mine but "hand tight" is a fairly subjective term.

[Joseph]

Well, basically, on cars i've always hand tightened them, on this seeing leak i thought maybe it should be tighter. So i did.

Then checking the haynes it stated screw till contact then 2 turns, so thats what i did on my last attempt

Anyways. No idea whats going wrong. 

[banoffee]

Sounds like you’ve tried everything else, so it’s now time to try a turbo

Maybe the Haynes typesetters fucked up and put 2 instead of 1/2

[Joseph]

Highly likely, i have a Reliant Robin they got the ignition timing setting wrong in the Haynes manual ahaha

But still, I must be missing something somewhere, it makes no sense

Just saying

[Crass]

Personally, irrespective of the instructions on the filter, I'm with Dezza. Tight as I can get it by hand then nip it up with a filter wrench no more than a quarter turn, probably less.

[Joseph]

Right, well turns out the 2 sump screws below the filter were not there, fitting them did get the engine drip free. 

Concentrating on finding the usuals stopped me from spotting that

How can to tight be a reason for leacking oil?

It can crimp up the oil seal mate, one of the reasons to put a smear of oil on it before fitting it.

Ok thanx for replying
