czakky Posted October 18, 2014 Share Posted October 18, 2014 Is that a head gasket? Probably too late but just out of curiousity how often do you torque the heads? Link to comment Share on other sites More sharing options...
docc Posted October 18, 2014 Author Share Posted October 18, 2014 . . . torque the heads . . . ? Link to comment Share on other sites More sharing options...
luhbo Posted October 18, 2014 Share Posted October 18, 2014 It needs cleaning? Link to comment Share on other sites More sharing options...
docc Posted October 19, 2014 Author Share Posted October 19, 2014 It needs cleaning? That's the method I went with! Now to see how long it stays clean . . . I thought I remembered an O-ring or something for oil to rise to the rocker box. (Trying to delay that Big Teardown until 160.000 km . . .)

gstallons Posted October 19, 2014 Share Posted October 19, 2014 Docc, there are o-rings under the rocker arm assys. that need replacing. Very easy to do. You have a parts catalogue that shows them ? Link to comment Share on other sites More sharing options...

Don't fix it until it's broken It's a pity that we can't make such great sentences in German.

docc Posted October 19, 2014 Author Share Posted October 19, 2014 "Sie mit es durcheinander, warum?" I was thinking of doing the heads, rear engine leak, clutch and flywheel all at 100,000 miles. If I can tolerate the oil leak that long. The clutch sounds like a Steampunk Drum Band. Link to comment Share on other sites More sharing options...
emry Posted October 19, 2014 Share Posted October 19, 2014 The clutch sounds like a Steampunk Drum Band. I love letting Harley riders hear the symphony that ushers from my clutch. Nothing better than watching them look down in concern trying to locate what broke just as I happened to pull up. Priceless, every single time.

docc Posted October 21, 2014 Author Share Posted October 21, 2014 Docc, there are o-rings under the rocker arm assys. that need replacing. Very easy to do. You have a parts catalogue that shows them ? So, I see the #16 O-rings (one per head) and the #21 O-rings (4 per head). The #16 was the one I was thinking could give a drizzle like this (?) I suppose I'll do them all in my upcoming 100,000 mile refresh. You know, the one I think I ought to do regardless of whether it really needs it. . . . polish and balance the rods, balance the pistons , yadda-yadda . . . warum, warum, warum???

You'll want to try to keep that cleaned off unit you have a chance to fix the leak. Mine leaked there in the past and the PO didn't clean it off. It's "cooked" on and I've tried everything but sandpaper to get it off. Someone suggested oven cleaner but I'm afraid that might discolor the aluminum.

luhbo Posted October 21, 2014 Share Posted October 21, 2014 In my opinion it's just an unnecessary risk of stripping one of the long anchor bolts.Retorque them after the first 50 miles or so, after the engine was well warmed up and all parts have settled, and that's it. I never had a problem with leaking head or cylinder seals.On the other hand: I'm a firm believer in Hylomar. May be that this helps a bit...

docc Posted October 21, 2014 Author Share Posted October 21, 2014 I would be remiss to retorque the heads now, after so many miles, unless I had removed them for the valves and guides. Hubert, Hylomar where? (Not on the head gasket!?) Link to comment Share on other sites More sharing options...
luhbo Posted October 22, 2014 Share Posted October 22, 2014 No, not on the gaskets. Only at the O-rings. Used it on old 2-stroke engines instead of the head gasket. Worked. After some years these rings might have lost all the elasticity they once had. In case they start to let the oil through they're quickly replaced anyway. Just remove the rocker bed and swap them. No new gaskets, no retorquing. Link to comment Share on other sites More sharing options...
