[Dirty Dave]

Got the old girl running and it smokes like a frieght train and i have oil dripping from mostly rear cylinder whats up since theres no valve guide seals? are my guides just that worn and can seals be put in? HELP

The Smoking Could Be Wore Valve Guides, If I Remember Right, when Going Down Hill If U  Let The Compression Hold U Back  For A Little Ways, Then Give It Throttle And It Smokes, Your Guides Are Wore, They Can Be Replaced....
If It Smokes All The Time It Could Be Wore Rings....If It Smokes On Start Up And Quits After A While That Might Be Check Valve and Spring In Oil Pump Letting Oil Seep.....It Could Also Be The Breather Timing, And It Is Building To Much Pressure Forcing Oil Past Rings,Valve Guides, Seals, Gaskets, If U Have A lot of Oil Leaks I Would Look @ The Breather Timing. I"m Sure There Is Better Info. Than This Out There....Someone Will Give U More Accurate Info.

Sounds like my 79 XLCH that i bought as a basket, the rear piston was not only worn out, it's broke.

Well i started checking afew things pulled pipes off and could see the oil running down the valve stem from the guide so i pulled the heads and the exhaust guides are worn and the valve seats are pitted so a valve job is in the works.
