Oil Additive Question/Rebuild

My 79 Shovel is showing it's age, beginning to smoke a little. The bike sat for about 10yr and then I have riden it for 8yr. As far as I know it has never been apart. (I knew the org. owner) I will be redoing the heads for sure this winter. I hope to see it through this riding season!
My question would be.

Has anyone ever tried an additive? Such as Lucas oil stabilizer. Or some other product?
Thanks

When they start smoking, you can use any additive you want, and it will still smoke. The best bet, is to go ahead and do the rebuild. But that is easy for me to say.

Give the Lucas oil a shot. It will definitely buy you some time. All of the additive packages are pretty comparable honestly.

I had good luck making it through a season on a smoking ride with a really expensive racing oil. Sorry forgot the name. It was like three times the price of shelf oil.
It still smoked, but not as much as the cheaper oils...

a cap full of marvel mystery oil in your GAS will help lube the topend, i bought a year of life for my shovel before the rebuild with this. When it did start sticking an exhaust valve it didn't seize or hurt the motor, but i stopped at that point.

1979 a year of lemons. Best to go thru it due to chance of guides going bad and they also had a batch of improperly hardened barrels that ended up having a bad wear pattern that causes smoking and excessive oil use.

Speaking of 79's and smoke...does anyone know if they were coming from the factory with valve guide seals then?

Did any shovels have seals from the factory?

OK, Lucas heavy duty oil treatment- added
MMO in the gas- added and in the tool bag.
Smoke- we'll see!
Riding for this season- Yabet!

Re: Oil Additive Question/TIME

I post this with some reservation. I am no where near the level of mechanical ability most of you have. I can spin a wrench, fix problems, rebuild things and have built two or three basket cases. I can bust a knuckle, jump up and down, spit and cuss with the best of'em. But that's where my knowledge ends and trial and error take over.

So sticking with the theme of this bike, "don't fix it unless it's broke." I find it is time to fix the smokey condition. I convinced myself it was just the guides and planned on pulling the heads for a quick rebuild. But then again the best laid plans....

This is what I found after removing the rear head.


That is the good side, here is the other...

I can harley wait to continue the tare down! What will I find next?

All the new oils for the past sevaerl years are reformulated to be "epa" correct and there alot thinner. Try valvoline straight 60 weight racing oil like the nitro cars run. Its still the old oil "with zinc" it will cure the problem.

Correct me if I'm wrong Jesse..........I believe '81 and later Shovelheads got seals from the factory. TK.

Forget the Lucas. Looks like it is time for new jugs.

Yeah, so much for the additive. Looks like both clips came out, the cylinder is scared on both sides.
What about a sleeve?
