Funnily enough I used slightly oversized o-rings last time I put it back together. 17x2.65 water jacket o-ring instead of 17.3x2.4, and 10x1.8 balancer shaft o-ring instead of 10x1.3. Maybe go even bigger on the WJ one next time? Didn't notice any coolant coming from the little hole - all my concentration was on the sight glass watching the oil go milky....

Also when you have the clutch cover off Check the depth of the little o ring slot on the left hand crank case then measure the Thickness of the o ring. You would like to have about 1mm crush. Sometimes the groove is way too deep.
Definitely have a look for those tomorrow. Might even be able to face taking the clutch cover off.....again!

Cool. I forgot to add the clutch cover gasket reduces crush of that o ring as well

I hadn't fully considered what you said when I responded earlier - I'm not ready for a full strip down and rebuild on this engine! Been planning to attempt it eventually (with guidance). Going to see if I can get a 17x3 or even 3.5 o-ring in there and hope that cures it. Reckon I may be able to ease the casing back far enough to swap that out without pulling the water pump seal over the edge, must be worth a try. If all else fails, what's the availability like on a good used liner for a 550?

if you use the kickstart o ring like we sell then that would do. give it a little stretch first and then cover on quick.

Ok, stuck a fatter o-ring in there and still no joy. Cracked liner or liner o-rings as mentioned seems the likely culprit then?? What are the options for diagnosing this without tearing down the engine please? Borescope? Leak down test? Any advice much appreciated.

well I block the jacket hole with a little rag etc around my air jet and pump it up. you want the airline pressure to be low. I just turn the electricity off and run the tank down. takes about a minute.

but at the end of the day, once it isn't in the left cover it's engine down.....

Seems I'd best get cracking and strip it down then - had to happen sooner or later, but timing is bad. Thanks all for the help so far. I'll keep this updated with my findings....
