OK, yes, that second picture looks troubling….Did it look like this when you first pulled it apart? Don’t be offended, but I’m assuming you have the rod cap oriented properly, there are very small line up tabs that need to match up. Do you have the right number of needles in there? Those little buggers are super easy to lose…I lost one once, it ended up jamming between the piston and intake port…”Found it”….
Do you have those needle liners properly oriented and seated in the rod? If not, the rod may have never been properly secured to the cap, even though the proper torque was used. Unfortunately, I think you better start with a new needle/liner set…Perhaps you can find a reasonably priced on ebay…Or, perhaps from a member…I guess I would line up the rod cap and rod, the perhaps secure the halves off the crank without the liners to see if the rod somehow get distorted from improper installation..Needless to say, it the rod has become distorted, it is not usable…
