Oil filter leak

skidlids · 14-Aug-2020, 23:30

Certainly isn't a common problem, I've removed the double threaded boss before to fit a oil deplector plate for an oil cooler but never had any problems

I have seen a few comments recently where some owners don't seem happy with the sealing of the K&N oil filters but as I don't use them I can't really comment

It might be worth a google search

Hi Kev
Thanks for the reply. Mine isn’t a K&N but I suppose it could be the same issue as it does have a welded nut for removal. Talking to a guy in the pub last night he recons it could be a blocked crank case breather.

It could be the breather the later injected bikes have a Reed valve but not the earlier 750 that I know of.
Hopefully not worn bores/rings causing blow by and pressurising the crankcases

It’s done 29,000 miles and been stood for 3 years. Started straight away on same battery after a recharge. I guess a lot of sediment in the engine maybe caused the problem.
