[QUOTE="Ducdude, post: 23738, member: 2077"] Well today was not a good day working on the Shadow... The goal was to quell an oil leak at the FT exhaust pushrod tube and while that went as expected as far as getting the seals out and off that was not the location of the leak. To make matters worse despite warning to take care and get the pushrod back in the lifter's cup I screwed that up and did not realize it till I tried to kick it though with the compression release, I got 2 or three kicks before I realized I messed up.. The damage is one chewed up ball end of the FT exhaust push rod. I pulled the rod and dropped in an old but serviceable one to evaluate the function or lack there of. The valve seems to operate correctly and the bike runs but it does not seem to do so as smoothly or as quietly as before. The adjustment may be a tad looser then nil as I was quite miffed when I did it, hence perhaps the reason for the loud valve and ruff running or not. I will replace the old rod with a new one as soon as I get one but the question begs to be asked...What other damage do I now have to be concerned about...What should I look for and how? To add insult to injury the front cylinder is still leaking on the mag cover...The head is dry and there is only oil below the head heaviest on the push rod side on the fins foward of the cylinder and oil drops the mag cover... So could oil be leaking out between the head and the muff/liner?? Another thought was oil somehow spraying out from the lower pushrod seal? It's a long shoot but what ever... The front oil lines and the tappet and valve covers are all sound and dry. Where else could the oil be coming from? I am open to any Thoughts on this as well as my new push rod potential damage issues.. Thanks, Eric [/QUOTE]
