Looking for the current conventional wisdom.
Inside the oil filter housing - that pressure relief ball and spring.
In Jeff's (ME109) case the spring broke and ate his bearings.
I am wondering (at 120,000 km) if I should just check it, or replace it anyway on suspicion of metal fatigue.
Springs are funny things - not all that rare for a new one to break prematurely and an old one last a long time.

Top of the morning to you Doug. Btw, how's that hip of yours?

The oil filter 'bypass' spring and ball.............. if the ball is spring loaded, I would be happy with that, no action required.

A check at each oil filter change is a good idea.

If the spring does break, imo it will take some time for the spring to break into smaller pieces, which is when the problems begin.
I think the time for the spring to break into smaller pieces is longer than an oil filter change interval at 6,000 miles.

Anything with a diameter of just under 1/8" will do for a testing poker.
The length of the poker needs to be about 7-8"

The 'poker' needs to have a squared end and not a pointed end (as in a skewer) as it slips of the ball too easily.

The ball only needs to be pushed in a max of 1/8", and will not harm anything.

A simple check for peace of mind.

So the awl that I've been useing isn't such a good idea.

This weekend is oil changes and get ready for winter projects.
Thanks for the tips, I will check the spring as you described.

Hip is good Jeff - thanks. It won't ever be the same as before, but at my age more than a few parts are like that.
How many chaps can say their body contains more stainless and titanium than their bike?!
Cheers Mate.

I dunno Garnet, what is an awl?

I use the pointed end of my chainsaw file perfect diameter, squared end and perfect length.

I tried to use a piecost once but it was no good.

I can! Well . . . I could back when I had a bike.

I've got a pretty good sized chunk of stainless steel holding my right hip together . . . from hitting the side of a 4 wheeler at about 50 mph.

Hi Scot.
Hope you trashed the 4 wheeler.

Yeah . . . caved it in real well; but of the two vehicles involved, my '78 R80/7 certainly got the worse end of that deal!

Shit.
Can you ride?
Are you getting another bike?

Yeah, Dougie. No worries. That whole deal happened back in '93, and I've had another bike since then. Unfortunately, I had to sell my pride and joy 4 months ago because I lost my job. Now that I'm back among the employed, I'll be shopping for another probably next year. I'm thinkin' maybe a Guzzi or a K75RT.
