Valve ticking, noise on the front jug Options

[spritee1]

My problem started out with a eratic ping I was getting from the 88 on my 06 deuce. It did not have any rhythm to it just a ping, then a ping ping, then another ping ping. Could not pin it downas to where the noise was coming from. It just kept getting louder. The noise sounded like a hollow metal on metal collision. I thought it might be coming from the exhaust pipe. Then on a ride I lost power from the front cylinder. I was running down the interstate at the time, so I limped to the next exit and got off. The engine seem to idle ok and I did not here the problem metal on metal sound again.
Now I have the sound of the tapping of the valves from the front lung. It has been getting louder. I finally have taken of the rockerarm cover and the rockerarm assemble. Everything looks good on visual inspection. There seems to be a little more play in the exhaust rockerarm then in the intake. is there a possibility the ticking noise I am hereing might be coming from the rocker hitting the rocker assembly mount. Any ideas where I should proceed from here?

Ol' Paint had a tickin' like that for years.......'bout drove me fuckin' nuts. (IMG:style_emoticons/default/banghead.gif)

Til we were on our way to Reliance and got hit by that semi tire. (IMG:style_emoticons/default/schreck.gif)

Tore the Gremlin bell Joey G gave us off the bottom of the frame and sent it bouncing down the road past Seth and Ryan's heads. (IMG:style_emoticons/default/holysheep.gif)

after that........... the tickin' quit. (IMG:style_emoticons/default/yes.gif)



BTW.....welcome to the shop. Good luck with your problem. Seahag should be on shortly to really confuse you.

BTW- You got any pics of them JUGS? (IMG:style_emoticons/default/whistling.gif)

Sounds like a bad lifter

[wholehog]

are you getting good compression readings on both cylinders? You might have burnt a valve or the valve stem is sticking in the guide and snapping closed...gotta try to listen with a sthetoscope to pinpoint it

[spritee1]

Thanks. But a lifter was not the answer. I don't feel it was a valve. I went out for a ride after replaceing the lifters. Same tick. Then I got the ride up to highway speed. Within a short period the noise got progressively worse until the engine started missing Now its clacking very loud and engine won't idle. seems to still turn over fine.

had the shop take it down. Found out it was a bearingfor the cam that gave it up. The cam was beating the casing up and the rollers from the bearing was ground up and spread through the motor. Costly conclusion.

[wholehog]

this was an inner bearing failure?

Ouch!

[spritee1]

this was an inner bearing failure?

Yes it was.

did the bike have stock cams and were the bearings stock? The stock inners have not been prone to failure at 30K miles unless you go with a high lift and stiffer springs....

I assume the cam is shot but what about the right side case?

put in torrington full complement bearings !!!!!

(IMG:style_emoticons/default/banghead.gif) (IMG:style_emoticons/default/hysterical.gif) Im doing the ticking serch as well , its valve train noise, i put in the tapered pushrods from fueling , chromoly, and changed lifter 3 times , from stock , to upgrade to fuelings midgrade tappet( tapered tappet bodies ), so its not that. also upgraded to screaming eagle oil pump, so its not that. PLus i dropped the hose from the oil cooler and did an oil swap the pump pushes fine. now this is important- ive seen my valve's , if you have a 2005 and up you already have bee hive valve springs so its not coil bind, also the shop looked up the bike and let me see the diagram. IN 2005 Harley switched to bee hive valve springs- so save your money.I have 33k on my cycle and the valve stems look new. Its not a warped valve because you blow smoke , so its not that. i inspected and re torqed the rocker arms when putting in the tappered pushrods so its not that. The inner cam bearings have been replaced with torringtons 148, so its not that.
the rocker arms did have play to move latterally but the rear cyclingder rockers had more and are quiet so its not that.
Next time you warm up your bike do it with the bike sitting upright and listen, and warm up every time with the bike upright and listen. Ive also replaced the flapper valves with a whole new assembly so its not that. both cyclinders.

Push rods , first was the stock solids, changed them to HD quick install- flexing, they rubbed and left halo's, changed them to chromoly pushrods fueling , ok.
what i thing might be the problem is airation of the oil, The airated oil enters the lifter and the lifter is put under compression the aair is squeezed out leaving insufficient oil in the tappet. nest oil i try is shell rotella 20-50 v , is suppose to be anti airation oil.

ps not an exhaust leak either gaskets are new.
the other thing is under the primary sprocket , the cover that makes up the charging system ,the cover that fits over the windings. A guy at the shop showed me one and it was toasted, the left side affects the right side possibly because they all ride on the pinion and affect center.
the last thing ill try is johnson hylift tappets -greater volume theory better valve , and replacing the rocker assembly with a tp unit, they say more girth produces less noise, only one way to find out. also will replace the original primary chain to rule out tight spots, sitting in garage already, and finally check the cover that goes over the field windings to charge/run bike , that will just about cover everything except the valve guide.
