Default Cylinder and lifter caskets leaking. Blowby?

First I want to say a massive thank you to everyone that makes this site work and the community of helpful tinkerers. This has been my first Harley and when I have been banging my head against the wall you guys have been there to help me out.

Yet again I could do with some opinions on my 1988 1200cc sportster engine. I have not done any work on the engine since buying the bike a couple of years ago. The frame is a 1994 and the bike was registered as such but as an 883. So I'm not sure if the engine started out life as an 883 or not.

Just recently the rocker gaskets, cylinder gaskets and lifter gaskets have began to weep. I have also noticed some white smoke and coming from the crankcase breather, that increase with revs. My oil is not overfilled. Its at the bottom end of the dipstick when stood up and warm, but does look quite black. I was thinking it could be blowby but I'm not burning any oil at the exhaust the exhaust gases are invisible!

I am planning on opening up the engine later this year but need the bike for work. Should I be worried?

I have tried to show the leaks below. This is after a ride to work and back 8 miles each way.

8 miles is a short distance. The smoke is probably moisture in oil which is created by short distances. If you are not, you should take it on a longer trip at least once a week so that the engine heats up enough to get rid of the water in oil.

Those leaks don't look to bad to me. When was the last time you wiped it? The base gasket leak looks a bit worse though...

That is just my opinion. Wait for someone else to chime in.

Give it an oil/filter change and maybe re-torque the top end.
Oil level is usually ok around the half way mark.

This will not cure the base leak but you can give it a try. But do not overtight any of the bolts!!!

According to the VIN (CAP) that I can see, your engine started out as a XLH1200 if it is an 88 model.

Check that the vent line to the oil tank isn't pinched or kinked.
Also, I see you have a breather on your cam vent.
Do you still have the breather baffle in the cam chest?
A problem with either of these can increase crankcase pressure and possibly blow out seals / gaskets.

First thing I would do is clean the engine real thorougly. Use brake cleaner or some other degreaser to get it clean and dry. After that take a ride to see where the leak (or sweating/weep) is actually coming from. Sometimes it comes from places other than you had focused on.
Very nice bike BTW.

For sure your base gaskets are leaking, but not TOO bad. If you replace them, prepare for some serious time, as they took me about 6 hours to remove, since the ptfe (I'm guessing) had melted to the aluminum, and you have to be so gentle, since it's an aluminum surface. I wouldn't worry about the rocker box leaking, though, since the pressure shouldn't build up unless your breather bolts are clogged. The smoke is definitely bad news, though. Are you overheating?

It could be that the umbrella valve (26856-82) has died in the breather. The lack of a non-return valve is likely to increase crankcase compression
and hence gasket seepage. It is easy to check. Gently puff down the breather hose (after cleaning it!) and see if you get resistance. The
valve should close. It needs replacement if it doesn't. They are getting hard to find but some on here have succeeded recently.

Have you done a compression test?

The umbrella valve doesn't really do much except ensure some circulation in the upper rocker, instead of the same stale air staying stagnant (and, arguably to keep oil from blocking the passage), since the other side doesn't have an umbrella valve, and just flows freely. There is no way that could affect compression in any measurable way. I think the gasket is probably not put in properly. Even when I am really careful, I get the upper rocker gaskets
pinched half the time. It's tough getting it on straight with so little clearance!

F.W.I.W. My 2000 was a weeper, I was second owner, and I learned that after doing my rocker gaskets that meticulous assembly is critical. The three piece rockers are fun but when reassembled be sure to keep good vertical alignment with all three pieces, and when tightening up do it in steps a wee bit at a time, also checking your alignment as you go. A side note was I had difficulty getting the base rings on the pushrod tubes to seal well. I invested in the one pice bases, reasonable, and really saved some headaches.
