PaintItBlack Posted February 20 Share Posted February 20 (edited) got to whip the head off my 1085BB GS1000, have recently heard the O ring isn’t required with the cometic fibre head gasket, is that correct, and could the fact that I fitted an O ring last time I had it apart be the reason why the head gasket never really sealed, and got progressively worse , pain in the arse as runs really well, but covers the engine and my jeans in oil every time I ride it Edited February 20 by PaintItBlack Quote Link to comment
gs7_11 Posted February 21 Share Posted February 21 Doesn't sound right to me. Pretty sure mine's got an o-ring. Quote Link to comment

Yeah I’m not convinced it’s right either, read the O ring wasn’t used with the cometic gasket somewhere, can’t remember where now, so when I ordered the gasket from Suzuki performance spares I asked if the O ring was needed, he didn’t know so went and asked someone else and they said it’s not used with that gasket, but he didn’t sound very positive, so I’m not convinced and still not certain Quote Link to comment
gs7_11 Posted February 21 Share Posted February 21 Isn't it the new (genuine Suzuki) MLS head gaskets that don't need the o-ring? Quote Link to comment

Yes I believe that’s correct, Can’t see why the O ring wouldn’t be used with the cometic fibre gasket, it’s just that I’ve been advised that it’s not used , could be the guy at sps was confusing the cometic and genuine Suzuki gaskets Quote Link to comment

Do put some liquid gasket on the front, and a bit to the sides, of the chain tunnel Quote Link to comment

gs7_11 Posted February 21 Share Posted February 21 If you compare these 2 gaskets (Cometic fibre and Suzuki MLS) you can see the difference in the cam chain tunnel area, and why one needs an o-ring and one doesn't). It's stated on Fowlers website that the new genuine MLS gaskets don't need o-rings. Fibre gaskets still do. Basically, if the gasket has a space for the o-ring, fit one. 1 Quote Link to comment

It's just a chain tunnel, no pressure on the oil, just a lot of splatter. Oil is mostly on the front and back, never had problems at the back. The headgasket is a gasket, so why would it create problems? I didn't put an O-ring in because I didn't had one. The teardrop ones at the bottom can be reused too, but do measure the thickness!! If the thickness is still the same you could do it, if they're thinner, replace them. Also feel if they're still soft, if they're hardened replace them!

Thanks again, have ordered an o ring now (how does that little piece of rubber cost £30), so will be using it when I do the job 1 Quote Link to comment
johnr Posted February 26 Share Posted February 26 Is it that o ring that's leaking? Plenty of oil leaks on heads are due to the o rings on the centre cylinders head nuts. 1 Quote Link to comment

The outer nuts have copper washers, but I never have seen O-rings on other nuts.. Quote Link to comment

I think you are confusing this GS head with a GSX one - all head nuts on GS head are external, so just need steel / copper washers. Quote Link to comment
