Dave. I’m probably wrong, but it “looks like” the oil is dripping down from somewhere above (but where would that be?).

The fact the leak didn’t start until you beefed up the oil pressure says something. Gaskets and seals just can’t handle it?

It’s ridiculous what they charge for the clutch side gasket. Like you said, $30. And it’s not even the good one with the metal inside.

The oil is not coming from up above the engine cases - the cylinder and head is dry as a bone. The oil residue is limited to the top of the right side engine case - with small spots being wind blown to the area behind the starter. After putting the new cylinder and head on I only rode the bike a few short miles before switching the pump gears - so I can't confirm that the leak wasn't there prior to changing the gears. The engine did not leak oil in this spot previous to the cylinder/head change.

The new $30 gasket does have the steel center - you can see the shiny silver layer at the edge with the black covering bonded to both faces, and a magnet does pull on the gasket confirming there is steel inside.

Reply #436 - 09/14/24 at 07:36:46 Where did you get your gasket? My recent purchase was at Partzilla and it doesn’t have the metal. I need to compare are my part # to your part # when I get back home. Sorry I threw that out there about a leak from above. I know you know this better than me!

Decided to look it up before getting back home.

Your gasket part # ends in B20. My gasket # ends in B11 for my model K5. Apparently that’s the difference. B20 is the good one, but same price?

And what the heck is the difference between all the different models k5-k9? There are other model difference for other year bikes and I’ve always attributed it to California models or European models or something like that.

Makes me want to order a B20 gasket and overlay it onto a B11 gasket…. Is there an extra hole or passage or something?

Sorry for hijacking your post!

Reply #439 - 09/14/24 at 11:22:27 Looks to be random airborne drops varying in size. Start at the top , work your way down. But really dye works so good , looks like lava. Sure it’s not coming from breather ? Fresh piston , increase in crankcase pressure , just sayin.

Dave, how is you oil leak investigation going?

That picture of the oil droplets on top of that decorative cover behind the starter sure does look like oil that fell down from above. Have you looked at the 8mm head stud directly below the intake port. I assume you are running a MLS head gasket. Oil loves to migrate through the layers of those MLS gaskets. That 8mm stud is pretty close to the oil feed passage.

The cylinder, head and head cover are completely dry and clean. I have removed the fuel tank and looked them over repeatedly. I have stuck a new Q-tip in every fin, nook and cranny of the head looking for any signs of oil. The 8mm nut under the intake is clean and dry.

The oil droplets seem to be coming from the top of the right side clutch cover. That place leaks oil and the wind catches it and blows it behind the cylinder.

I am going to try replacing the clutch cover with a clutch cover that hasn't been struck by a disintegrating clutch cam and see what happens. If the leak persists I will remove the oil pump overdrive gears and see if the leak goes away.

It would be a shame to remove those overdrive gears to resolve an oil leak. Have you considered doing an air test?

Mine is dry as a bone after 4500 miles since last clutch cover removal. Same gasket over & over. No sealant. The chronic little weep at the RR head gasket has been resolved. I had that long before switching to the overdrive gear set. I don’t recall FinnHammer having any issues with leaks. I think a man of your caliber can fix this little leak.

Reply #444 - 09/22/24 at 03:17:02 I got a replacement side cover to try - it needs to be cleaned up and polished before it is mounted. It won't happen for a couple of weeks as we are busy doing other stuff right now......no time to play motorcycle for a while.
